Fewer ideas have been more toxic or harmful than the idea of the biological reality of race, and with it the idea that humans of different races are biologically different from one another. For this understandable reason, the idea has been banished from polite academic conversation. Arguing that race is more than just a social construct can get a scholar run out of town, or at least off campus, on a rail. Human evolution, the consensus view insists, ended in prehistory.
Inconveniently, as Nicholas Wade argues in A Troublesome Inheritance, the consensus view cannot be right. And in fact, we know that populations have changed in the past few thousand years—to be lactose tolerant, for example, and to survive at high altitudes. Race is not a bright-line distinction; by definition it means that the more human populations are kept apart, the more they evolve their own distinct traits under the selective pressure known as Darwinian evolution. For many thousands of years, most human populations stayed where they were and grew distinct, not just in outward appearance but in deeper senses as well.
Wade, the longtime journalist covering genetic advances for The New York Times, draws widely on the work of scientists who have made crucial breakthroughs in establishing the reality of recent human evolution. The most provocative claims in this book involve the genetic basis of human social habits. What we might call middle-class social traits—thrift, docility, nonviolence—have been slowly but surely inculcated genetically within agrarian societies, Wade argues. These “values” obviously had a strong cultural component, but Wade points to evidence that agrarian societies evolved away from hunter-gatherer societies in some crucial respects. Also controversial are his findings regarding the genetic basis of traits we associate with intelligence, such as literacy and numeracy, in certain ethnic populations, including the Chinese and Ashkenazi Jews.
Wade believes deeply in the fundamental equality of all human peoples. He also believes that science is best served by pursuing the truth without fear, and if his mission to arrive at a coherent summa of what the new genetic science does and does not tell us about race and human history leads straight into a minefield, then so be it. This will not be the last word on the subject, but it will begin a powerful and overdue conversation.

Editorial Reviews
Review
“Extremely well-researched, thoughtfully written and objectively argued…. The real lesson of the book should not be lost on us: A scientific topic cannot be declared off limits or whitewashed because its findings can be socially or politically incendiary…. Ultimately Wade’s argument is about the transparency of knowledge.” --Ashutosh Jogalekar, Scientific American
“Nicholas Wade combines the virtues of truth without fear and the celebration of genetic diversity as a strength of humanity, thereby creating a forum appropriate to the twenty-first century.” --Edward O. Wilson, University Research Professor Emeritus, Harvard University
“A freethinking and well-considered examination of the evidence “that human evolution is recent, copious, and regional.” --Kirkus Reviews
“Wade ventures into territory eschewed by most writers: the evolutionary basis for racial differences across human populations. He argues persuasively that such differences exist… His conclusion is both straightforward and provocative…He makes the case that human evolution is ongoing and that genes can influence, but do not fully control, a variety of behaviors that underpin differing forms of social institutions. Wade’s work is certain to generate a great deal of attention.” --Publishers Weekly
“Mr. Wade is a courageous man, as is anyone who dares raise his head above the intellectual parapet; he has put his argument with force, conviction, intelligence, and clarity.” --The New Criterion

Evolution, Race and History
Since the decoding of the human genome in 2003, a sharp new light has been shed on human evolution, raising many interesting but awkward questions.
It is now beyond doubt that human evolution is a continuous process that has proceeded vigorously within the past 30,000 years and almost certainly—though very recent evolution is hard to measure—throughout the historical period and up until the present day. It would be of the greatest interest to know how people have evolved in recent times and to reconstruct the fingerprints of natural selection as it molded and reworked the genetic clay. Any degree of evolution in social behavior found to have taken place during historical times could help explain significant features of today’s world.
But the exploration and discussion of these issues is complicated by the fact of race. Ever since the first modern humans dispersed from the ancestral homeland in northeast Africa some 50,000 years ago, the populations on each continent have evolved largely independently of one another as each adapted to its own regional environment. Under these various local pressures, there developed the major races of humankind, those of Africans, East Asians and Europeans, as well as many smaller groups.
Because of these divisions in the human population, anyone interested in recent human evolution is almost inevitably studying human races, whether they wish to or not. Scientific inquiry thus runs into potential conflict with the public policy interest of not generating possibly invidious comparisons that might foment racism. Several of the intellectual barriers erected many years ago to combat racism now stand in the way of studying the recent evolutionary past. These include the assumption that there has been no recent human evolution and the assertion that races do not exist.
The New View of Human Evolution
New analyses of the human genome establish that human evolution has been recent, copious and regional. Biologists scanning the genome for evidence of natural selection have detected signals of many genes that have been favored by natural selection in the recent evolutionary past. No less than 14% of the human genome, according to one estimate, has changed under this recent evolutionary pressure. Most of these signals of natural selection date from 30,000 to 5,000 years ago, just an eyeblink in evolution’s 3 billion year timescale.
Natural selection has continued to mold the human genome, doubtless up until the present day, although the signals of evolution within the past few hundred or thousand years are harder to pick up unless the force of selection has been extremely strong. One of the most recent known dates at which a human gene has been changed by evolution is from 3,000 years ago, when Tibetans evolved a genetic variant that lets them live at high altitude.
Several instances have now come to light of natural selection shaping human traits within just the past few hundred years. Under the pressure of selection, for example, the age of first reproduction among women born between 1799 and 1940 on L’Isle-aux-Coudres, an island in the Saint Lawrence River near Quebec, fell from 26 to 22 years, according to researchers who were able to study an unusually complete record of marriages, births and deaths in the island’s parish records.
The researchers argue that other possible effects, like better nutrition, can be ruled out as explanations, and note that the tendency to give birth at a younger age appeared to be heritable, confirming that a genetic change had taken place. “Our study supports the idea that humans are still evolving,” they write. “It also demonstrates that microevolution is detectable over just a few generations in a long-lived species.”
Another source of evidence for very recent human evolution is that of the multigenerational surveys conducted for medical reasons, like the Framingham Heart Study. Borrowing statistical methods developed by evolutionary biologists for measuring natural selection, physicians have recently been able to tease out certain bodily changes that are under evolutionary pressure in these large patient populations. The traits include age at first reproduction, which is decreasing in modern societies, and age at menopause, which is increasing. The traits are of no particular importance in themselves and have been measured just because the relevant data were collected by the physicians who designed the studies. But the statistics suggest that the traits are inherited, and if so, they are evidence of evolution at work in present-day populations. “The evidence strongly suggests that we are evolving and that our nature is dynamic, not static,” a Yale biologist, Stephen Stearns, concludes in summarizing 14 recent studies that measured evolutionary change in living populations.
Human evolution has not only been recent and extensive; it has also been regional. The period of 30,000 to 5,000 years ago, from which signals of recent natural selection can be detected, occurred after the splitting of the three major races, and so represents selection that has occurred largely independently within each race. The three principal races are Africans (those who live south of the Sahara), East Asians (Chinese, Japanese and Koreans) and Caucasians (Europeans and the peoples of the Near East and the Indian subcontinent). In each of these races, a different set of genes has been changed by natural selection, as is described further in chapter 5. This is just what would be expected for populations that had to adapt to different challenges on each continent. The genes specially affected by natural selection control not only expected traits like skin color and nutritional metabolism but also some aspects of brain function, although in ways that are not yet understood.
Analysis of genomes from around the world establishes that there is indeed a biological reality to race, despite the official statements to the contrary of leading social science organizations. A longer discussion of this issue is offered in chapter 5, but an illustration of the point is the fact that with mixed-race populations, such as African Americans, geneticists can now track along an individual’s genome and assign each segment to an African or European ancestor, an exercise that would be impossible if race did not have some basis in biological reality.
The fact that human evolution has been recent, copious and regional is not widely recognized, even though it has now been reported by many articles in the literature of genetics. The reason is in part that the knowledge is so new and in part because it raises awkward challenges to deeply held conventional wisdom.
The Social Science Creed and Evolution
It has long been convenient for social scientists to assume that human evolution ground to a halt in the distant past, perhaps when people first learned to put a roof over their heads and to protect themselves from the hostile forces of nature. Evolutionary psychologists teach that the human mind is adapted to the conditions that prevailed at the end of the last age, some 10,000 years ago. Historians, economists, anthropologists and sociologists assume there has been no change in innate human behavior during the historical period.
This belief in the recent suspension of evolution, at least for people, is shared by the major associations of social scientists, which assert that race does not even exist, at least in the biological sense. “Race is a recent human invention,” proclaims the American Anthropological Association. “Race is about culture, not biology.” A recent book published by the association states that “Race is not real in the way we think of it: as deep, primordial, and biological. Rather it is a foundational idea with devastating consequences because we, through our history and culture, made it so.”
The commonsense conclusion—that race is both a biological reality and a politically fraught idea with sometimes pernicious consequences—has also eluded the American Sociological Association. The group states that “race is a social construct” and warns “of the danger of contributing to the popular conception of race as biological.”
The social scientists’ official view of race is designed to support the political view that genetics cannot possibly be the reason why human societies differ—the answer must lie exclusively in differing human cultures and the environment that produced them. The social anthropologist Franz Boas established the doctrine that human behavior is shaped only by culture and that no culture is superior to any other. From this point of view it follows that all humans are essentially interchangeable apart from their cultures, and that more complex societies owe their greater strength or prosperity solely to fortunate accidents such as that of geography.
The recent discoveries that human evolution has been recent, copious and regional severely undercut the social scientists’ official view of the world because they establish that genetics may have played a possibly substantial role alongside culture in shaping the differences between human populations. Why then do many researchers still cling to the notion that culture alone is the only possible explanation for the differences between human societies?
One reason is, of course, the understandable fear that exploration of racial differences will give support to racism, a question addressed below. Another is the inherent inertia of the academic world. University researchers do not act independently but rather as communities of scholars who constantly check and approve one another’s work. This is especially so in science, where grant applications must be approved by a panel of peers, and publications submitted to the scrutiny of editors and reviewers. The high advantage of this process is that the statements
scholars make in public are usually a lot more than their own opinion—they are the certified knowledge of a community of experts.
But a drawback of the system is its occasional drift toward extreme conservatism. Researchers get attached to the view of their field they grew up with and, as they grow older, they may gain the influence to thwart change. For 50 years after it was first proposed, leading geophysicists strenuously resisted the idea that the continents have drifted across the face of the globe. “Knowledge advances, funeral by funeral,” the economist Paul Samuelson once observed.
Another kind of flaw occurs when universities allow a whole field of scholars to drift politically to the left or to the right. Either direction is equally injurious to the truth, but at present most university departments lean strongly to the left. Any researcher who even discusses issues politically offensive to the left runs the risk of antagonizing the professional colleagues who must approve his requests for government funds and review his articles for publication. Self-censorship is the frequent response, especially in anything to do with the recent differential evolution of the human population. It takes only a few vigilantes to cow the whole campus. The result is that researchers at present routinely ignore the biology of race, or tiptoe around the subject, lest they be accused of racism by their academic rivals and see their careers destroyed.
Resistance to the idea that human evolution is recent, copious and regional is unlikely to vanish unless scholars can be persuaded that exploration of the recent evolutionary past will not lead to a resurgence of racism. In fact, such a resurgence seems most unlikely, for the following reasons.
Genomics and Racial Differences
In the first place, opposition to racism is now well entrenched, at least in the Western world. It is hard to conceive of any circumstance that would reverse or weaken this judgment, particularly any scientific evidence. Racism and discrimination are wrong as a matter of principle, not of science. Science is about what is, not what ought to be. Its shifting sands do not support values, so it is foolish to place them there.
Academics, who are obsessed with intelligence, fear the discovery of a gene that will prove one major race is more intelligent than another. But that is unlikely to happen anytime soon. Although intelligence has a genetic basis, no genetic variants that enhance intelligence have yet been found. The reason, almost certainly, is that there are a great many such genes, each of which has too small an effect to be detectable with present methods. If researchers should one day find a gene that enhances intelligence in East Asians, say, they can hardly argue on that basis that East Asians are more intelligent than other races, because hundreds of similar genes remain to be discovered in Europeans and Africans.
Even if all the intelligence-enhancing variants in each race had been identified, no one would try to compute intelligence on the basis of genetic information: it would be far easier just to apply an intelligence test. But IQ tests already exist, for what they may be worth.
Even if it were proved that one race were genetically more intelligent than another, what consequence would follow? In fact, not much of one. East Asians score around 105 on intelligence tests, an average above that of Europeans, whose score is 100. A higher IQ score doesn’t make East Asians morally superior to other races. East Asian societies have many virtues but are not necessarily more successful than European societies in meeting their members’ needs.
The notion that any race has the right to dominate others or is superior in any absolute sense can be firmly rejected as a matter of principle and, being rooted in principle, is unassailable by science. Nonetheless, races being different, it is inevitable that science will establish relative advantages in some traits. Because of genetic variants, Tibetans and Andean highlanders are better than others at living at high altitudes. At every Olympic games since 1980, every finalist in the men’s 100-meter race has had West African ancestry. 9 It would be no surprise if some genetic factor were found to contribute to such athleticism.
Study of the genetics of race will inevitably reveal differences, some of which will show, for those who may be interested, that one race has some slight edge over another in a specified trait. But this kind of inquiry will also establish a wider and more important truth, that all differences between races are variations on a common theme.
To discover that genetics plays some role in the differences between the major human societies does not mean that that role is dominant. Genes do not determine human behavior; they merely predispose people to act in certain ways. Genes explain a lot, probably far more than is at present understood or acknowledged. But their influence in most situations is or can be overwhelmed by learned behavior, or culture. To say that genes explain everything about human social behavior would be as absurd as to assume that they explain nothing.
Social scientists often write as if they believe that culture explains everything and race nothing, and that all cultures are of equal value. The emerging truth is more complicated. Human nature is very similar throughout the world. But though people are much the same, their societies differ greatly in their structure, their institutions and their achievements. Contrary to the central belief of multiculturalists, Western culture has achieved far more than other cultures in many significant spheres and has done so because Europeans, probably for reasons of both evolution and history, have been able to create open and innovative societies, starkly different from the default human arrangements of tribalism or autocracy. People being so similar, no one has the right or reason to assert superiority over a person of a different race. But some societies have achieved much more than others, perhaps through minor differences in social behavior. A question to be explored below is whether such differences have been shaped by evolution.
Social Behavior and History
The purpose of the pages that follow is to demystify the genetic basis of race and to ask what recent human evolution reveals about history and the nature of human societies. If fear of racism can be overcome sufficiently for researchers to accept that human evolution has been recent, copious and regional, a number of critical issues in history and economics may be laid open for exploration. Race may be a troublesome inheritance, but better to explore and understand its bearing on human nature and history than to pretend for reasons of political convenience that it has no evolutionary basis.
It’s social behavior that is of relevance for understanding pivotal—and otherwise imperfectly explained—events in history and economics. Although the emotional and intellectual differences between the world’s peoples as individuals are slight enough, even a small shift in social behavior can generate a very different kind of society. Tribal societies, for instance, are organized on the basis of kinship and differ from modern states chiefly in that people’s radius of trust does not extend too far beyond the family and tribe. But in this small variation is rooted the vast difference in political and economic structures between tribal and modern societies. Variations in another genetically based behavior, the readiness to punish those who violate social rules, may explain why some societies are more conformist than others.
Social structure is the point at which human evolution intersects with history. Vast changes have occurred in human social structure in all three major races within the past 15,000 years. That is the period in which people first started to switch from the nomadic life of hunter-gatherer bands to settled existence in much larger communities. This wrenching shift required living in a hierarchical society instead of an egalitarian one and the temperament to get on with many strangers instead of just a few close kin. Given that this change took so long to occur—modern humans first appear in the archaeological record 200,000 years ago, yet it took them 185,000 years to settle down in fixed communities—it is tempting to assume that a substantial genetic change in social behavior was required and that it took this long to evolve. Moreover, this evolutionary process took place independently in the populations of Europe, East Asia, the Americas and Africa, which had separated long before the first settlements emerged.
The forager-settler transition is unlikely to have been the only evolutionary change in human social behavior. Probably from the beginning of agriculture some 10,000 years ago, most people have lived on the edge of starvation. After each new increase in productivity, more babies were born, the extra mouths ate up the surplus and within a generation everyone was back to a state of scarcity little better than before.
This situation was accurately described by the Reverend Thomas Malthus with his analysis that population was always kept in check by misery and vice. It was from Malthus that Darwin derived the idea of natural selection. Under conditions of the fierce struggle for existence that Malthus described, favorable variations would be preserved, Darwin perceived, and unfavorable ones destroyed, leading eventually to the formation of new species.
Given that the human population supplied Malthus with the observations that led Darwin to the concept of natural selection, there is every reason to suppose that people living in agrarian societies were subject to intense forces of natural selection. But what traits were being selected for during the long agrarian past? Evidence described in chapter 7 indicates that it was human social nature that changed. Until the great demographic transition that followed industrialization, the wealthy had more surviving children than the poor. As many of the children of the rich fell in status, they would have spread throughout the population the genes that support the behaviors useful in accumulating wealth. This ratchet of wealth provides a general mechanism for making a specific set of behaviors—those required for economic success—more general and, generation after generation, gradually changing a society’s nature. The mechanism has so far been documented only for a population for which unusually precise records exist, that of England from 1200 to 1800. But given the strong human propensity for investing in one’s children’s success, the ratchet may well have operated in all societies in which there have been gradations of wealth.
The narratives constructed by historians describe many forms of change, whether political, military, economic or social. One factor almost always assumed to be constant is human nature. Yet if human social nature, and therefore the nature of human societies, has changed in the recent past, a new variable is available to help explain major turning points in history. The Industrial Revolution, for instance, marked a profound change in the productivity of human societies, one that took almost 15,000 years to emerge after the first settlements. Could this too have required the evolution of a difference in human social behavior, as significant as the one that accompanied the transition from foraging to settled life?
There are other significant turning points in history for which scholars have proposed a clutch of possible causes but no compelling explanation. China created the first modern state and enjoyed the most advanced civilization until around 1800 ad, when it slid into puzzling decline. The Islamic world in 1500 ad surpassed the West in most respects, reaching a high tide of its expansion in the siege of Vienna in 1529 ad by the forces of the Ottoman Sultan Suleiman the Magnificent. Then, after almost a thousand years of relentless conquest, the house of Islam entered a long and painful retreat, also for reasons that defy scholarly consensus.
The counterpart of Chinese and Islamic decline is the unexpected rise of the West. Europe, feudal and semitribal in 1000 ad, had become a vigorous exponent of learning and exploration by 1500 ad. From this basis, Western nations seized the lead in geographical expansion, in military preeminence, in economic prosperity and in science and technology.
Economists and historians have described many factors that contributed to Europe’s awakening. One that is seldom considered is the possibility of an evolutionary change, that the European population, in adapting to its particular local circumstances, happened to evolve a kind of society that was highly favorable to innovation.
Economic Disparities
Explanation is also lacking for many important features of even today’s world. Why are some countries rich and others persistently poor? Capital and information flow fairly freely, so what is it that prevents poor countries from taking out a loan, copying every Scandinavian institution, and becoming as rich and peaceful as Denmark? Africa has absorbed billions of dollars in aid over the past half century and yet, until a recent spurt of growth, its standard of living has stagnated for decades. South Korea and Taiwan, on the other hand, almost as poor at the start of the period, have enjoyed an economic resurgence. Why have these countries been able to modernize so rapidly while others have found it much harder?
Economists and historians attribute the major disparities between countries to factors such as resources or geography or cultural differences. But many countries with no resources, like Japan or Singapore, are very rich, while richly endowed countries like Nigeria tend to be quite poor. Iceland, covered mostly in glaciers and frigid deserts, might seem less favorably situated than Haiti, but Icelanders are wealthy and Haitians beset by persistent poverty and corruption. True, culture provides a compelling and sufficient explanation for many such differences. In the natural experiment provided by the two Koreas, the people are the same in both countries, so it must surely be bad institutions that keep North Koreans poor and good ones that make South Koreans prosperous.
But in situations where culture and political institutions can flow freely across borders, long enduring disparities are harder to explain. The brisk and continuing pace of human evolution suggests a new possibility: that at the root of each civilization is a particular set of evolved social behaviors that sustains it, and these behaviors are reflected in the society’s institutions. Institutions are not just sets of arbitrary rules. Rather, they grow out of instinctual social behaviors, such as the propensity to trust others, to follow rules and punish those who don’t, to engage in reciprocity and trade, or to take up arms against neighboring groups. Because these behaviors vary slightly from one society to the next as the result of evolutionary pressures, so too may the institutions that depend on them.
This would explain why it is so hard to transfer institutions from one society to another. American institutions cannot be successfully implanted in Iraq, for instance, because Iraqis have different social behaviors, including a base in tribalism and a well-founded distrust of central government, just as it would be impossible to import Iraqi tribal politics into the United States.
With the advent of fast and cheap methods for decoding the sequence of DNA units in the human genome, the genetic variations that underlie human races can be explored for the first time. The evolutionary paths that have generated differences between races are of great interest to researchers and many are described in the pages that follow. But the broader significance of the worldwide variations in DNA is not the differences but the similarities. Nowhere is the essential unity of humankind more clearly and indelibly written than in the human genome.
Since much of the material that follows may be new or unfamiliar to the general reader, a guide to its evidentiary status may be helpful. Chapters 4 and 5, which explore the genetics of race, are probably the most securely based. Although they put the reader on the forefront of current research, and frontier science is always more prone to upset than that in the textbooks, the findings reported here draw from a large body of research by leading experts in the field and seem unlikely to be revised in any serious way. Readers can probably take the facts in these chapters as reasonably solid and the interpretations as being in general well supported.
The discussion of the roots of human social behavior in chapter 3 also rests on substantial research, in this case mostly studies of human and animal behavior. But the genetic underpinnings of human social behavior are for the most part still unknown. There is therefore considerable room for disagreement as to exactly which social behaviors have a genetic basis and how strongly any such behaviors may be genetically defined. Moreover the whole field of research into human social behavior is both young and overshadowed by the paradigm still influential among social scientists that all human behavior is purely cultural.
Readers should be fully aware that in chapters 6 through 10 they are leaving the world of hard science and entering into a much more speculative arena at the interface of history, economics and human evolution. Because the existence of race has long been ignored or denied by many researchers, there is a dearth of factual information as to how race impinges on human society. The conclusions presented in these chapters fall far short of proof. However plausible (or otherwise) they may seem, many are speculative. There is nothing wrong with speculation, of course, as long as its premises are made clear. And speculation is the customary way to begin the exploration of uncharted territory because it stimulates a search for the evidence that will support or refute it.

About the author

Nicholas Wade is the author of three books about recent human evolution. They are addressed to the general reader interested in knowing what the evolutionary past tells us about human nature and society today.
One, Before the Dawn, published in 2006, traces how people have evolved during the last 50,000 years.
The second book, The Faith Instinct (2009), argues that because of the survival advantage of religion, an instinct for religious behavior was favored by natural selection among early human societies and became universal in all their descendants.
A Troublesome Inheritance (2014), the third of the trilogy, looks at how human races evolved.
Wade was born in Aylesbury, England, and educated at Eton and at King's College, Cambridge, where he studied natural sciences. He became a journalist writing about scientific issues, and has worked at Nature and Science, two weekly scientific magazines, and on the New York Times.

Political expediency explains why human exceptionalism enjoys the status of scientific orthodoxy: one cannot allow that humans evolved significantly after groups left Africa, and maintain the ban on the taboo subject of racial differences. The politically correct (p.c.) who run the academedia complex assert dogmatically that races do not exist. Race is a social construct, they say; no important differences between or among large gene pools (one of the euphemisms for "race") can be detected. If any differences are found, they are judged inconsequential. According to the orthodoxy, human groups are interchangeable. Any significant group differences are solely due to culture, not genetics.
Wade's argument is that evolution did not stop when humans left Africa to roam and populate the planet. Human evolution continued both in Africa and beyond as tribes of humans had to adjust to changing conditions. The politically correct (p.c.) view is that all of these adaptations over thousands of years were cultural - the humans who departed Africa (perhaps 50,000 years ago) are the same as those who remained and the same as the drifters who moved to other continents. Wade disputes this. One example he gives is that of Tibetans who have evolved to breathe easily at high altitudes. Wade is silent about Bolivians, but if their genes have been similarly modified to the life in the Andes, then that would be an even more recent example of human evolution.
Wade contends that the 3 main races evolved to adapt to the different conditions which each encountered. (Wade includes Middle Easterners and Indians among the Caucasians). In northern climes, the lack of strong sunlight for much of the year led to the genetic mutation that resulted in lighter skins for most Caucasians. The same need led to genetic mutations that resulted in lighter skins for Northern Asians, but with them the process involved a different set of genes and nearby fields (alleles), and these resulted in changes beyond skin color. Because these changes in the population were found advantageous, those who had them were more likely to reproduce so the original beneficial mutation spread to most of the population in that group.
One experiment absent from Wade's book is one I saw on a television science program. Daniel G. Freedman and his Chinese wife observed new-borns in hospital cribs. When placed in position, Black babies would stir, move about, try to turn. They were obviously upset when someone, using a cloth, sought to close the nostrils to make them breathe through their mouths. White babies, by contrast, were less active, but they too fought against the cloth on the nose. Asian babies, when placed in the crib, generally just lay there. When the cloth obstructed air to the nostrils, they were slightly annoyed, but quickly adjusted to breathing through their mouths. All of these were babies 1 or 2 days old, so the differences are most likely the result of nature, not nurture; genetics, not culture. There were other tests, like holding the baby to have it walk in the crib. The African babies could even high-step; the Asian ones did not walk, their feet dragging along the sheets; and the whites were in between, neither dragging nor high stepping, but walking. This experimental evidence reinforces the hypothesis that races exist and have traits that express genetics, not simply culture.
As America slides into an anti-scientific, politically correct, orthodoxy, there are surprising examples of good scientific work that was conducted even in a more oppressive, egalitarian tyranny. In Stalin's Soviet Union, the Communists decided and declared that Mendelian genetics was false, and all scientists were required to accept the view of Lysenko that characteristics acquired in a lifetime could be passed onto the next generation. Lysenko's experiments in agriculture suggested higher crop yields for the Soviets, so only an enemy of socialism and the state would challenge such a promising approach. At least one scientist who did was executed. The egalitarian Soviets also banned IQ tests. For several decades, Lysekoism was the politically correct approach to inheritance in the USSR.
In Novasibirsk, Siberia, Dimitri Belyaev accepted Mendelian genetics, but suggested experiments that did not appear to overtly challenge the Communist scientific orthodoxy. He took silver wolves and used one trait to divide the group - aggressiveness. The most aggressive males mated with the most aggressive females; the least, with the least. Within only 6 generations, the gentle wolves were becoming less wolf-like, more dog-like. Though they were bred only on one attribute, on the aggressiveness axis, other changes also appeared - physical changes. This collateral "damage" or "advantage" was inherited too, in a cluster of changes. The skulls and heads of the gentle wolves became rounder, their coats lighter with some white fur. Ears drooped on some and the tails of others curled or shortened. So by looking at the physique of the animals, one could see a visible sign of a changed temperament. One group would enjoy being around humans. The snarling, threatening other group was unfriendly.
Is this true of people? While in the US, the p.c. "scientists" who dominate the social sciences proclaim that race does not exist, and that it is merely a "social construct," Wade and others contend that human races do exist, and that there may be considerable and significant differences among them.
Belyaev, in addition to experimenting in breeding wolves, also bred generations of Siberian gray rats. Again, he divided them into 2 groups on the aggressiveness axis. After several generations, some of the rats would place their snouts out their cages so humans could pet them. The other group would jump at the cages trying to attack people who entered the compound. All had the same genes, but the areas between those genes, the clusters of alleles were now different.
Wade notes that a gene in humans is associated with aggression. It may appear in almost all, but some have many controllers of the MAO-A gene to restrain its effects. Humans with only 2 controllers are much more likely to be involved in violent crime. Males with only 2 inhibitors are 0.1% of the white population, but 5.0% among Afro-Americans. Thus, Afro-Americans are 50 times more likely to lack sufficient inhibitors of this gene than whites. Though Wade does not explore this startling statistic, it might go a long way to explain the high violent crime rate among Black males, far more than the usual p.c. explanations that invoke "racism," poverty, and unemployment.
Wade contrasts humans with chimps, who he states are the closest primate relative to humans. Chimps are territorial, selfish, warlike, and the females have as many sexual encounters as possible. Humans in the hunter/gatherer stage were also territorial and warlike, but they tended to have one mate and knew (and presumably trusted) their relatives. Society was egalitarian. Wade says there were no priests, but I question this. I suspect even such a primitive society required a shaman, who knew a bit of medicine, the story of the group, how to forecast weather, etc.). With the development of agriculture, settlement followed, and with it hierarchy, inequality, a priesthood, trade, and the necessity to obey the boss and the military commander. Because early governments are weak, the tribe remains important for meting out justice, and Wade maintains it is the default human institution, continuing into the modern state with nepotism.
Stronger states had to overcome the exploitative nepotism of tribal traditions. In China, this was accomplished through examinations, a necessary requirement to be inducted into the bureaucracy. For over a millennium these examinations emphasized memorization, intelligence, and conformity.
Later Islamic society achieved a strong state by creating bureaucratic slavery. Because their religion forbade them enslaving fellow Muslims, they took teenaged boys from Christian families in provinces like Greece and Serbia, rode them off to be enslaved, converted and trained to work for the Islamic state. They were not allowed to marry, but could rise in the military and bureaucracy on their own merits. Having no families, they were less likely to be corrupt, and their loyalty was to their master, the head of state. Wade is weaker in describing how the Muslim Mughal Empire in India handled the problem of overcoming tribalism. He does make the well-known point of how tribalism among the Mongols prevented their march to the Atlantic Ocean through Europe, when the Mongol emperor died and had to be replaced.
Wade also fails to describe a Western bureaucracy that could serve the state and other institutions instead of their families. Catholic priests and nuns clearly provided civil services to European leaders at least from the time of Charlemagne. Nepotism was reduced. The churchmen did extract a price for this service that Wade does discuss, a price some might deem too high: namely that the ruler was to submit to Christian law. Not even an emperor was above the law in Christian Europe (at least in theory). Wade does emphasize that this is one feature that made Europe unique and aided its advance over other civilizations. Another group that also provided civil services in some parts of Europe was the Jews. In some places, they collected the taxes for the kings. Everywhere, they were money lenders, bankers, doctors. Unlike the vast majority of Europeans, most Jews could read. Because of their professions, they had to learn math, even before the 0 was imported into Europe.
Wade also contends that over the generations, the Chinese became both more intelligent and more conformist. Those who passed the national examinations rose in rank, esteem, and wealth, and thus, had more children who would inherit their characteristics. Over the centuries, the attributes for success in that culture became more widespread through inheritance. Their success in commerce was evident throughout Southeast Asia, when many of the natives of Indonesia, Philippines, etc., became ever jealous of the Chinese success.
Yet, the Chinese prescription for success in one area may have become a liability in another. From about 1400 to 1435 the Chinese Emperors sent out large naval expeditions. The best known was that of Admiral Zheng He, and it was enormous - some 30,000 men on 250 ships. They traveled down SE Asia over to India, and then across to the Arabian Peninsula, the Red Sea, and East Africa. They returned to China with giraffes, ostriches, and other exotic items. Massive as Zheng He's venture was, he basically followed well-known trade routes. Although some speculate he may have sent smaller expeditions far beyond, nothing became of them. Then, a new emperor came to the throne in China who was uninterested in such ventures. He ordered the destruction of the fleet and of all ocean-going vessels. Chinese exploration ceased. By 1800, the Chinese empire stagnated.
Around 1500 Christopher Columbus set sail from Spain for India. His 3 ships were small and the crews totaled only 90 men. Magellan's fleet of 5 ships and 260 men would circle the globe, but only 1 ship and 18 men would make it back to Spain. And it would be 80 years before Sir Francis Drake would accomplish the deed a 2nd time. While it is now commonplace in the West for students to sneer that Columbus did NOT discover America, they are to be pitied for they illustrate the results of anti-Western, multicultural education. Of course, others made it to the New World before Columbus. But what the relatively tiny expeditions of Columbus and Magellan and the other European explorers accomplished - they united the world as never before! They were the first globalists. Henceforth, Old World and New would be part of the mental maps of sailors; they would be known, and better known in time. What became of Zheng He's massive expeditions? Basically, nothing. And many scholars in China at the time, sought to erase all history of his expeditions from the documents. Forbid further exploration, burn the fleets, destroy the documents. China did not require new knowledge. By contrast, the explorations of the Europeans would unite the world in maps, and change the world in countless ways.
One of the weakest examples Wade presents to bolster his argument for on-going human evolution is occurs on page 3. Between 1799 and 1940 on an island near Quebec the age of reproduction of young women fell from 26 to 22 years. I remain unconvinced that that proves genetic change, and suspect changes in the culture probably better explain the statistics (e.g., were there more nuns in the community in the earlier period? How would they affect the average age? What were the society's views on sex, illegitimacy, etc.?) I think Wade weakens a strong case with a weak example.
Instead, Wade should have included the racial differences revealed in the crib studies of babies a few days old conducted by Dan Freedman and his Chinese wife. Or he might have noted the racial disparity in twins - among Asians 4 per 1,000; among whites, 8; among Africans, 16. Such evolution may not have been as recent as the Quebec studies, but it does indicate change after the 3 major races diverged (I prefer not to give a specific date for when this group left Africa, or when whites and North Asians split, because I think such dates are speculative and may well change with new discoveries. The main point is that the 3 main races were separate enough to evolve with different characteristics, including rates of twins.)
Wade assures his readers that races are so real that "By taking just a few measurements, physical anthropologists can tell police departments the race of a skull's former owner with better than 80% accuracy."(70) "How could they identify a skull's race so accurately if race doesn't exist?"(70) In July 1996 in the western US state of Washington, two men attending a hydroplane race stumbled upon human remains. They informed the authorities, and the sheriff viewing some of the bones thought a white man had been killed perhaps a century ago. Was it a case of murder? The victim had been shot in the leg - but with an arrow. The local authorities were perplexed, and asked university scholars for advice. When the bones were tested for age, they were "one of the most complete ancient skeletons ever found; bone tests have shown it to date from 7300 to 7600 B.C." as en.wikipedia described it. Soon a political and legal battle erupted, with the local Amerindian tribes claiming the bones as those of their ancestors and seeking to rebury them. This occurred during the Democratic Administration of Pres. Bill Clinton, and if there is a conflict between science and political correctness, Democrats trash science. Clinton had the Federal Government bury the site where the bones were found to prevent any other finds that might offend the so called Native Americans.
By chance, CBS TV's Evening News of 7 October 2014 with Scott Pelley included a segment on Kennewick Man. Note the omissions. The "... skull was found in 1996, along the banks of the Columbia River near Kennewick, Washington. Doug Owsley is the Smithsonian's top anthropologist. Eighteen years ago he and a group of scientists sued the federal government and local Indian tribes for the right to study a 9,000 year old skeleton - known as `Kennewick Man.'.... Sculptors took months to build a likeness based on the shape of his skull and archival photos from Asian coastal people. `Kennewick Man's' bones have been locked away by the federal government, but Owsley says there's still so much to learn - including what finally killed him."
Pelley never mentioned that the first impression was that the skull was that of a white man. When sculptors sought to create a likeness of the dead man, they did not think European, but instead considered someone who trod the Bering Sea route. Were they doing this because the skull appeared Asian, or because the orthodoxy is that all in the New World are derived from the Asian route? How much time did the scientists have to examine the skeleton? And the bones are now "locked away by the federal government." I ask, are they locked beside the "lost" emails of Lois Lerner and the autopsy files of JFK?
If whites were in the New World before the Asians, and killed and were exterminated by them, there would be less "white guilt" and consequently less support for preferences for Amerindians. Law suits, courts, and years of contention followed this most remarkable discovery. Some scientists finally concluded that the victim was an Ainu, whom some say is related to whites and/or Polynesians. But the scientists were allowed only short periods to study the remains. Bill Clinton's view of science is similar to Stalin's - the political trumps the scientific. But if Kennewick man was just a regular white of European origin, as originally thought, how then explain that one of the earliest skeletons in North America, near the West Coast, is white? Perhaps the population of the New World did not simply come from Siberia via the Bering Sea area. Wade accepts the common view of the Bering crossings and includes genetic similarities between North Asians and Amerindians - hair and teeth - to support his view. He also asserts: "Another two continents fell into the position of the pale-skinned northerners...for people living in Siberia...to Alaska they migrated southward to colonize...North and South America."(81) Are the Amerindians really the pale skins?
Moreover, some of the early Olmec statues have Negroid features. Were there seafarers from Africa who made it to the New World before Columbus? And we now know that the Viking forays into North America were not merely myths. Moreover, there are art objects in the New World where the faces appear Caucasian. Perhaps there were more "pale faces" before Columbus than Wade is willing to recognize.
Wade informs readers, "There are almost certainly genes that predispose people to regard incest as abhorrent,..."(250-251, and he makes a similar point on 237) Although there is some dispute as to just what it entailed and how wide-spread it was, brother-sister marriage may well have been prevalent in Egypt for the thousands of years of its independence, down to the last Pharaohs when Cleopatra married her younger brother Ptolemy. If this was the case, were the consequences so awful for a civilization that lasted and flourished for nearly 4,000 years?
Wade describes the simple test of delayed gratification developed by Walter Mischel: a child is offered a marshmallow now, or 2 marshmallows if he waits 15 minutes.(157) Those who could wait, restraining their immediate impulses, tended to be more successful in later life. Strangely, Wade omits mention of the racial differences in this experiment. Generally, East Indians delayed, Blacks did not.
Wade includes a terrific example of the contrasts among civilizations with his discussion of the telescope, invented in 1608 by the Dutchman, Hans Lippershey. Within a few years, this invention was shown to leaders of the Ottoman, Mughal, and Chinese empires. While the 2 Muslim empires grew ever more hostile to science, even banning the printing press in the case of the Ottomans, it was only the Europeans who used the new telescope invention to revise their view of the universe, and only the Europeans who improved the invention so it could be used not only to study the movement of the stars, but those of oncoming ships and the location of enemy troops.
While little came from Zheng He's massive naval expeditions, those of Columbus, Magellan, and the other Europeans changed the world. Was the difference in the genes? Was the failure of China due to inherited conformity, or cultural complacency? The Chinese invented the printing press, and Muslims banned it under pain of death. The Europeans embraced it. Soon there were hundreds of presses in numerous European countries, encouraging literacy among the populace. Who read the books printed in China? In Europe, with its alphabets of about 30 letters, it was much easier to learn to read (and print) than in China, with its thousands of characters. Literacy became a more democratic aspect of Western culture.
Wade writes that the "theme of human history is that each race has developed the institutions appropriate to secure survival in its particular environment."(136) Is this true? Wade devotes an entire chapter to the Jews, whose specialization in certain professions for more than a millennium, Wade contends, altered their genetic inheritance. Unlike most others, Wade declares that it was not simply laws that banned Jews from farming and owning land and other occupations, but that money lending was quite profitable, which led many Jews to a profession forbidden to Christians (and Muslims) for centuries. Over time, Wade contends, Ashkenazi Jews developed, bred for, and passed on higher IQs (along with collateral damage of diseases that afflict mainly Jews). Because of Jewish ability to assess people (their creditworthiness) and manipulate numbers (even before the symbol of 0 was imported into Europe to simplify calculations), they thrived as capitalism developed. Although only 0.2% of the world's population in the first half of the 20th century, they won 14% of the Nobel Prizes; 29% during the second half, and 32% of those prizes from 2000 to 2007. (198) Jewish success could be seen in numbers, too. From a population of 1 million in 1500, they grew to 16.5 million in 1939.
However, if Jews were genetically successful for adaptation to capitalism, this adaptation brought them to near extinction in Europe by 1945. They seemed to have a harder time adapting to socialism. When Europe was dominated by National Socialists, Jews were hounded for discrimination and later extermination. The defeat of Hitler seemed to end that threat. Although Jews thrived at first under Soviet socialism (see, Yuri Slezkine's Jewish Century), the Soviet one-party dictatorship had second thoughts about Jews after WWII and the establishment of the state of Israel. Some contend that Stalin was preparing a major round-up of Jews to be sent to camps within the USSR. Only Stalin's death aborted his plan to destroy the Jews under the Soviet version of socialism. So, the Jewish genetic adaptation of intelligence, cleverness, and entrepreneurship was suddenly a burden, a badge of oppression when nations turned to socialism. Thus, in 1934 Dr. Goebbels could proclaim that the age of over-refined Jewish intellectualism was at an end. It was nearly the end of everything and everyone Jewish in Europe. Genetic adaptation for one environment, might become deadly when that environment changes. And for social animals like humans, society IS environment too. Jews, well-adapted for capitalism, were nearly exterminated under socialisms. However, their adaptation to capitalism led to another charge: was there anything to the claim that Jews used their "privileged" position in Germany - wealth, intelligence, culture, Nobel Prizes - to oppress the gentile population of the nation?
Wade discusses the rise of the West and how its changed genetic composition contributed to this process - as Europe became less violent, more trusting, more literate, more work-oriented, more willing to delay gratification. Wade contends there was almost a necessary genetic change before the Industrial Revolution could begin. There was a dialectic between the genetic makeup of society leading to changes, which produces more wealth, and more children inheriting the newly correct genes, that could then continue to alter the general society. Wade contrasts the necessity of a wider circle of trust of strangers for a modern state, to the narrow range of trust found in tribal societies. And this is one reason the institutions of modern states cannot easily be replicated in tribal societies like Iraq, Afghanistan, and other Middle-Eastern areas. Tribal kingdoms tend to restrict trust within "the family."
"Western societies are well adapted to present economic conditions, which they have in large measure created." (248) Although in the same paragraph Wade notes possible changes in culture, he avoids the big question raised by his book. In 1950 the US was 90% white, 10% African-American. In less than a century the US white population will become a minority. Hate-the-West, hate-whitey Democrats like Bill Clinton and Barack Obama cheer this prospect. However, will there continue to be Western values in a Third World America? Will the intelligence level be the same? The work ethic? The creative spark? The language? The crime rate? Already sociologists (presumably, reliably left-leaning) note that in multicultural neighborhoods, there is a remarkable decline in trust, in community, and a rise in isolation, anomie. And what is true of America is true of the Netherlands, Germany, Sweden, England, and what is left of the "West." As non-Western genes begin to dominate Western nations, will the future of America and the West be Detroit? And who opened the American borders so an invasion of millions could change the composition, and color, of the nation? What privileged elite was able to use the values of the West - the greater trust of strangers - to import the Trojan horses of massive 3rd World invasion? If the West is to survive as the West, it may have to shed some of these "genetic" values - and soon.
I am less concerned about the rise of China, Japan, India, Brazil, or Nigeria, than I am by the decline of the West. This decline is obvious in the demographics. One value that helped build the West, a greater capacity to trust strangers, has been turned against us. Our social immune system is now attacking our healthy cells, oblivious to the foreign elements. How did this happen? How can it be reversed?
Wade is aware of some of the horrors that resulted from racism. Several times he discusses the cost of such policies. But he never raises the issue of the cost of anti-racism and egalitarianism. What has been the cost of the equality ideology? To abolish inequality and oppression, Cambodia, a land of about 8 million, killed off 2 million. Under Mao in China, millions of Chinese were starved so socialism could be built. Same under Stalin. Same under Lenin. Egalitarianism has cost the lives of up to 100 million people in the 20th century. In America, the egalitarian, and excusiological approach to crime has undoubtedly encourage more crime, especially Black on white crime, murder, rape, etc. Since 1960, how many innocent whites have been murdered by Blacks? (The left may excuse or even deny that these are crimes, alleging that whites are by definition privileged and deserving of what punishment they receive from the Blacks, and Franz Fanon and his followers stressed the necessity of violence against the "oppressor").
Implementing egalitarian ideology has also extracted an enormous economic cost. Massive aid to Africa has done little to raise the standards of living of its people, despite large deposits of natural resources. Similarly, in much of the Middle East, the oil revenue has not brought wealth to many of the people living there. In America welfare has waxed but the main result is more single mothers raising more children without fathers, without discipline, filled with resentment, on the track to pursue a life of crime. More graduate from high school and even college, but many of them are barely literate. Where instead should the money have been spent?
Some may read this review as an attack on Black people. I have great respect for Blacks like Thomas Sowell, W. E. B. Du Bois, John Hope Franklin, Jackie Robinson, and yes, I admire the moral strength of Martin Luther King, Jr. So what if King was given the name Michael; so what if he plagiarized some of his dissertation (if we perused all the dissertations in numerous subjects, I suspect considerable plagiarism would be revealed; so what if he engaged in some sexual romps while married; the point is that under enormous pressure and attempted blackmail from the US Federal Government {and undoubtedly local ones too}, King refused to yield, refused to cave, and kept fighting for what he believed right). I admire many more Blacks, too, but this is not the place for such a list. Surely some Blacks have enormous intelligence. And creativity? Just think of music? Blacks may be as kind and friendly as any other. They may well be stronger and faster. If Black on white crime is high in the US, Black on Black crime is even higher.
If Blacks are much more likely to inherit the MAO-A gene with few inhibitors, it does not necessarily mean they will become violent criminals. And if all races inherit genes adapted to help them survive in changing environments, then will the MAO-A gene help Blacks survive in our changed environment? As America and the West become ever more multicultural and multiracial, and as multicultural neighborhoods result in less trust, more distrust, more isolation, more anomie, as the cities of the West become more chaotic and crime-ridden, perhaps the MAO-A gene and its propensity to violence may be the best survival strategy in the new anarchical social environment. Due to length, for full review, see my blog.
Nicholas Wade’s book, “A Troublesome Inheritance” is the most iconoclastic and provocative book of the decade. Read it or be square. Wade is the science writer for the NY Times and his book is a compilation of the latest scientific data on “race” and continuing human evolution. Regardless of whether you agree with his hundreds of individual data points, they should be read.
OUT OF AFRICA TO AUSTRAILIA, THE ‘LUCKYCONTINENT’
Modern humans first left their African homeland approximately 50,000 years ago. Life was hard and total human population was in the thousands. The humans leaving may have consisted of a single band of hunter-gatherers. All of them would have had a black skin color that was perfectly adapted to their equatorial/tropical environment. Within 4000 years, their very much changed ancestors had reached Australia.
Humans had spread across the world by a process of population “budding.” When a group grew too big for the local resources, it would split………….these little groups would have been highly territorial and aggressive toward neighbors. To get away from one another and find new territory, bands started moving north into the cold forests and steppes of Europe and East Asia…... The evolutionary pressures for change on these small isolated groups would have been intense. Living by hunting and gathering, they would have had to relearn how to survive in each new habitat.
The mixing of genes between these little hunter-gatherer bands was limited. Even if geography had not been a formidable barrier, these groups were territorial and mostly hostile to strangers. How do we know? Until the modern era, humans had to find spouses in their immediate neighborhood. DNA analysis can often pinpoint ancestors to within a few miles in Europe, Asia or Africa.
Under conditions of a fierce struggle for existence -where most humans were often within a hair’s breadth of starvation - favorable genetic variations would be preserved, and unfavorable ones destroyed. Humans were/are no different than Darwin’s finches in the Galapagos.
When Europeans first arrived in Australia some 150 years ago, the indigenous natives were scarcely changed physically or culturally despite the intervening 46,000 years. The Australians of today call their country “the lucky country” so richly endowed is it with fertile land natural resources.
PHYSICAL DIFFERENCES BETWEEN THE “RACES”
SKULLS: Human skulls fall into three distinctive shapes, which reflect their owners’ degree of ancestry in the three main races, Caucasian, East Asian and African. African skulls have rounder nose and eye cavities, and jaws that protrude forward, whereas Caucasians and East Asians have flatter faces. Caucasian skulls are longer, have larger chin bones and tear-shaped nose openings. East Asian skulls tend to be short and broad with wide cheekbones.
LIGHT AND DARK SKIN: In equatorial areas where ultra-violet light is intense, evolution promotes dark skin to protect the body from overdosing on Vitamin D which can be fatal. Light skin is advantaged in the northern latitudes where ultra-violet light is weak
25,000 years ago in Europe, only those humans in the northern-most latitudes had white skin. Then, the glaciers advanced south one more time, forcing bands of men to move south. The light-skinned people living in northern latitudes did not wait for the glaciers to bury them. They moved south ahead of the advancing ice fields and as they did so they displaced and probably killed the darker-skinned people to the south in what is today France, Spain and Italy.
The East Asian “race” evolved in a very cold environment. Their white skin is caused by a combination of entirely different genes. East Asian nostrils are narrower and they have a fold of fat over the eyelid, which seem helpful in conserving body heat. The hair of East Asians is thicker than the hair of Europeans and Africans (who both share the same version of a gene called EDAR). And they have entirely different sweat glands. Most Asians in the north have a watery ear wax, as opposed to the hard ear wax of Europeans. (Evolved to keep insects out of the ear).Also in the north of Asia, shovel shaped front teeth are predominate. And Asian women tend to have smaller breasts.
These are not absolute racial characteristics. For example, the proportion of the population with watery ear wax and shovel teeth decreases as one moves from north to south Asia. The boundaries of race are thus imperfect.
But does this mean that “race” is not a meaningful concept? Is it a coincidence that for 50 years every finalist in the Olympic 100 meter race was of West African ancestry? Or that Ashkenazi Jews have an average IQ of 110-115 (the highest of any ethnic group) and are grossly over-represented among Nobel Prize winners? (See the politically incorrect explanation, infra.)
RECENT PHYSICAL EVOLUTIONARY CHANGES
An adaptation that has occurred in the past 3000 years is the ability of Tibetans to live at high altitudes. Only a little older is the gene change that allowed middle Europeans to consume milk products. Our original African ancestors had a strong lactose intolerance. This is an instance where a cultural change – the herding of cattle – preceded a genetic change.
Many different genetic changes have arisen to protect humans from malaria. Africans developed unique genetic protection; but as is so often is the case, there is a downside: if they receive this protection from both parents, sickle-cell anemia can result. Italians and Greeks have an entirely different evolutionary-based resistance to malaria, but, for them, this can result in “thalassemia” diseases.
HUMAN BEHAVIOR HAS BEEN SCULPTED BY EVOLUTION
Dogs use their hind legs to scatter grass and dirt on their feces. They don’t always do it, but obviously, if it didn't provide some evolutionary benefit, it would not be done. Newborn human babies will smile and look up into the face of the person holding them. We know that it is an instinct because even babies born blind will do it. Babies having this genetic adaptation were more likely to “bond” with their parents and, thus survive, and over time this became the inheritance of all human babies.
Nicholas Wade writes: “But the genes that govern human behavior seldom issue imperatives. They operate by setting mere inclinations, of which even the strongest can be overridden.”
FOR PROTECTION, WEAK VULNERABLE HUMANS TO DEVELOP SOCIAL ALTRUISM
When the first humans left the forest, they required radically different social behaviors, in particular, some degree of social altruism, if roving tribal bands were to provide weak individuals with protection. Chimpanzees, our closest primate relative, do not share at all within the group; even mother chimps, if they give any food at all to their young, give the least desirable parts!
In humans, says Wade, expectation of fairness and reciprocity and charitable sharing within the group “most probably” have a genetic basis. The urges to help, inform and share are “naturally emerging” in young children,…children instinctively want to actively seek to be part of a “we,” a group that has pooled its talents and intends to work toward a shared goal... “Social norms— even of this relatively trivial type— can only be created by creatures who engage in shared intentionality and collective beliefs.” Children instinctively protest when a new game is played wrong. People have an intuitive morality, derived from growing up in a particular social milieu, which is the source of instinctive knowledge that certain actions are right or wrong. People will fight to the death to protect their own group…. or attack that of others!
LAW: Law is rooted in several complex social instincts, including those for following rules, punishing violators of social norms and the sense of personal transgression that underlies self-punishment and shame.
WARFARE: Warfare is an institution doubtless inherited from the joint ancestor of chimps and humans, given that both species practice territorial-based aggression. In a tribal society such as the Yanomamö, aggressive men are highly valued and honored .
RELIGION: A propensity for religious behavior bound people together in emotion-laden rituals that affirmed commitment to common goals.
BLUSHING: Shame and guilt are the penalties…Social norms and punishment of deviants are behaviors embedded so deeply in the human psyche that special mechanisms have arisen for punishing oneself for infractions of social norms.
THE SCLERA: In all our primate cousins, the sclera (the white of the eye) is barely visible. In humans it stands out like a beacon, signaling to any observer the direction of a person’s gaze and hence what thoughts may be on their mind. The whites of the eyes are the mark of a highly social, highly cooperative species whose success depends on the sharing of thoughts and intentions.
OXYTOCIN AND THE RADIUS OF TRUST: Scientists have identified the neural hormone oxytocin, sometimes known as the hormone of trust. A small difference in the radius of trust may underlie much of the difference between tribal and modern societies. The trust promoted by oxytocin is not of the “brotherhood of man” variety. Oxytocin engenders trust toward members of the in-group, together with feelings of defensiveness toward outsiders.
THE RISE OF CITIES AND STATES: The rise of the first city-states, based on large scale agriculture, required a new kind of social structure, one based on large, hierarchically organized populations ruled by military leaders. The states overlaid their own institutions on those of the tribe. They used religion to legitimate the ruler’s power and maintain a monopoly of force. These new institutions will feed back into the genome over the course of generations, as those with the social behaviors that are successful in a militaristic society leave more surviving children.
RISE OF CITIES AND MIDDLE CLASS: A person with social skills and intelligence had a reasonable chance of getting richer, something that was seldom possible in a hunter-gatherer society. In England, the rich had more surviving children than did the poor. Middle-class culture spread throughout the society through biological mechanisms.” By 1851 only 8% of the richest surnames from the 1560 –1640 period had disappeared. The poor had a much greater risk of being erased from the gene pool.
CHILDREN WITH MIDDLE CLASS VALUES - GENETICALLY ENDOWED - PREDOMINATED: The values of the upper middle class— nonviolence, literacy, thrift and patience— were thus infused into lower economic classes and throughout society. Generation after generation, they gradually became the values of the society as a whole. This explains the steady decrease in violence and increase in literacy that researchers have documented in Europe.
THE MAO-A GENE: CIRCUMSTANTIAL PROOF THAT DECLINE IN VIOLENCE IN SOCIETY WAS GENETIC: The MAO-A gene, which influences aggression and antisocial behavior, is one behavioral gene that is known to vary between races and ethnic groups. In advanced European civilizations, extreme aggressivity no longer carried the same survival advantages, and the most bellicose members of a society were killed or ostracized, not honored, and their descendants gradually were erased from the gene pool.
GRACILIZATION/DOMESTICATION OF HUMANS AND ANIMALS
“Gracilization” is the lightening of bone in the body structure, a genetically based process, and has been documented by scientists in the fossil remains of species like pigs and cattle as they were domesticated from their wild forebears. The human fossil record shows that in the period prior to human settlements, which began some 15,000 years ago, there had been a gradual thinning of the human skeleton. Evolutionary Biologists believe that humans shed bone mass because extreme aggressivity no longer carried the same survival advantages.
BIOLOGISTS HAVE PROVEN THAT THEY CAN BREED TAME FOXES WHO DEVELOP FLOPPY EARS: Biologists have now selectively bred tame foxes. It took 40 years and 30 to 35 generations of breeding, but the foxes are now as tame and biddable as a dog. Though they did not breed for the trait, the foxes incidentally developed floppy ears.
THE BURNING OF CATS: A famous Midsummer Day festivity in 16th century Paris was to burn alive a dozen cats. The king and queen were usually present, and the king or the dauphin would light a pyre. The cats were then tumbled into the flames from an overhead basket, and the crowd reveled in their cries. “Certainly this is not really a worse spectacle than the burning of heretics, or the torturings and public executions of every kind,” sociologist Norbert Elias writes. “It only appears worse because the joy in torturing living creatures shows itself so nakedly and purposelessly, without any excuse before reason. The revulsion aroused in us by the mere report of the institution, a reaction which must be taken as ‘normal’ for the present-day standard of affect control, demonstrates once again the long term change of personality structure.” Elias argued that between medieval and modern times, a society wide shift has taken place toward greater sensibility. Wade argues that it has to do with a continuing evolution in behavior.
ASHKENAZI JEWS
IQ tests are routinely administered in the United States .European Americans score 100 (by definition— their scores are normalized to 100), Asian Americans score 105 and African Americans score 85 to 90. Oriental Jews and Sephardim have IQs comparable to Europeans. But Ashkenazi Jews, in addition to their cultural achievements, have high IQs generally measured at between 110 and 115 which is the highest average of any ethnic group. They also have a strange pattern of Mendelian diseases (e.g. Gaucher’s disease) which have a correlation with occupations requiring high intelligence. An interesting sidelight: Ashkenazi Jews have below average scores on visuo-spatial tests!
IN OUR SOCIETY IT IS POLITICALLY INCORRECT TO EVEN MENTION RACE-BASED INTELLIGENCE. A University of Utah based group completed a comprehensive study of Ashkenazi intelligence. But publication was another matter. Their report was submitted to several journal editors in the United States, all of whom said it was fascinating but that they could not publish it.
JEWISH ISOLATION: Jews originally were no different from anyone else: they were part of the general Near East population from which today’s Arabs, Turks and Armenians are also descended. But as soon as their religion started forbidding members to marry nonmembers, the Jewish population would have entered into reproductive isolation, much as if it had been placed on a remote island. Some large degree of reproductive isolation is the necessary condition for a population to take its own evolutionary path.
RABBINIC JUDAISM GAVE JEWS A NATURAL ADVANTAGE. As is well known, rabbinic Judaism is focused on Torah study that requires a high degree of literacy. From about 900 AD to 1700 AD, Ashkenazim were concentrated in a few professions, notably moneylending and, later, tax farming. A prevailing view has been that Jews were forced into money lending because other professions were barred to them. The Utah researchers reject this explanation. Using a wealth of historical detail they argue that Jews were not forced into moneylending but rather chose it because it was so profitable, and that they generally dispersed not because of persecution but because there were jobs for only so many moneylenders in each town. Moneylending required a high degree of cognitive skill and the rabbinical form of Judaism supplied them with same. Rabbinic courts oversaw contract enforcement and disputes. Because of the presence of Jewish communities in many cities of Europe and the Near East, Jews had access to a natural trading network of their coreligionists. Both the network and the dispute resolution mechanism were unusual and gave Jews a special advantage in long-distance commerce.
NATURAL SELECTION AND THE SHARP DECLINE IN THE JEWISH POPULATION CIRCA. 65 AD. Historical research has shown that the world-wide Jewish population declined dramatically from around 5.5 million in 65 AD to a mere 1.2 million in 650 AD. As I have tried to demonstrate before, the Romans were, if anything, philosemitic. Even with the Jewish revolt of 70AD, Jewish communities and leaders continued to be honored and respected. Unlike Christians, the Romans never launched a pogrom against Jews. The best explanation for the population decline is that large numbers of rural and uneducated Jews converted away from Judaism because of the high literacy requirements of the developing rabbinic- based religion. Generation after generation, as the uneducated and illiterate were shed from the community, the intelligence and propensity for literacy of those remaining would steadily rise. Because moneylending was so profitable, despite its high risks, Jews could afford to support large families and, like other wealthy people, could ensure that more of their children survived to adulthood.
After the devastation of the Jewish communities in Iraq and Persia and the expulsion of European Jews from England, France and many regions of Germany, their total population fell to fewer than 1 million in 1500 AD. But propelled by their new wealth, the Jewish population started to increase rapidly and by 1939 had reached 16.5 million. Because of the requirement for literacy, Jews found themselves better able than non-Jews to cope with the new cognitive demands of urban commerce. “Jews had the behavioral traits conducive to success in a capitalist society.”
CHINESE EXAMINATION SYSTEM: The probable effect of the system was to select for excellent memory, high intelligence and unwavering conformity. At each cycle, the Chinese population became enriched in survival skills. At the same time, authoritarian regimes ruthlessly repressed dissent, just as they do today….Over many generations, these upper-class Chinese values would have been throughout society as the more numerous children of the well off descended through the social strata.
CONCLUSION: THE RISE OF THE WEST IS AN EVENT, NOT JUST IN HISTORY, BUT ALSO IN HUMAN EVOLUTION.
Europeans are much like everyone else except for minor differences in their social behavior. (Inclination, but not imperative.) But these minor differences, for the most part invisible in an individual, have major consequences at the level of a society. As with most human behaviors, the genes provide just a nudge in a certain direction. But these small nudges, acting on every individual, can alter the nature of a society. There is almost certainly a genetic propensity for following society’s rules and punishing those who violate them. If Europeans were slightly less inclined to punish violators and Chinese more so, that could explain why European societies are more tolerant of dissenters and innovators, and Chinese societies less so.
FRANCIS FUKUYAMA: “The recovery of human nature by modern biology . . . is extremely important as a foundation for any theory of political development, because it provides us with the basic building blocks by which we can understand the later evolution of human institution.,”
Top reviews from other countries
All-in-all a very interesting and useful study of some of the implications arising from the fledgling science of genome analysis. This is just the beginning but already it seems that many left-wing pundits are rattled – some of the one-star reviews posted here are an indication of what might be termed the anxiety of the egalitarians. It goes without saying that any scientific study which may lead to a questioning of left-leaning academic orthodoxy is in danger of gaining taboo status.
In fact this book does NOT make a case for genetic determinism. The author argues that more general but significant differences can be seen and studied in the world's major racial groupings – that those minor but important differences probably have a genetic base. It has been assumed that evolution is a very slow process based on the successful adaptation of mutations. Mr Wade makes a case that minor but important changes can evolve in a much shorter time – perhaps as little as five generations. This field of genetic research is still very new but over time it will certainly reveal aspects of human nature that may not comfortably support of everyone's philosophy of mankind.
An important part of Mr Wade's thesis is the long term effects of those collective organisations he calls social institutions. Although individual creativity and intelligence are of tremendous importance it is Western institutions which have, over the past 500 years, enabled and encouraged the huge technological and intellectual lead all the world now benefits from. With that in mind, should we be worried that so many of our institutions are now falling under a well-meaning but censorious and restrictive form of moral control loosely labelled 'woke'?
