From 2003 till about 2006, I systematically went through them all, plus others that I had added in the course of this reading plan. Thus Leaky and Lewin sat in almost new condition on my bookcase for many years till I absorbed the whole thing finally in 2005.
Acquaintance
One reason I bought this book is because of my acquaintance with Richard Leakey. We never had an extensive relationship but I met him early in my experience as a young man in Africa. I met Richard in 1972 in Nairobi, when my wife and I were members of the Kenya Museum Society. While living in Kenya for about 25 years, we followed Richard's career in paleoanthropology, conservation and politics in the precarious rough and tumble of Kenya's volatile tribal atmosphere.
I appreciated Leakey's stand on moral and scientific standards. He resisted the pressures of political expediency and the pragmatism of a party trying to stay in power. The situation made it difficult for him to conduct some of the public duties even while he was the Director of the Kenya Museums.
Species Revision
Edith and I heard and early lecture by Richard, presented to the small group of Society members one evening, on the change in theory of human pre-history arising out of his discoveries. In this book Roger Lewin assists Leakey to present a scenario of pre-history, reconstructed from fossil findings and surmises of archaeologists.
A key theme is that Neanderthals and other humanoid beings were NOT direct ancestor species of the modern human, homo sapiens sapiens. This has been proven definitively now by DNA research. DNA also proves Leakey's theory that the human race had one common beginning, in Africa. This book is very informative.
Drama
Origins reads like a novel, which it basically is. There is a dramatic motif spinning out how it must have been, filling in from imagination the details to bridge the great gaps between the relatively few bones of various kinds from which a humanoid evolutionary history has been reconstructed.
The stories attempt to paint a picture of daily life and interaction with their environment. This novelesque approach helps bring to life these beings as real living individuals. There is extensive cultural information, however, on various human cultures.
Leakey and Lewin make important connections from various disciplines of science to explain aspects of human culture and suggest possible ways these practices and social structures arose in human history.
There is a concept of "convergence" that is used by many evolutionary scholars to make their case that evolution is real, factual and not only tells us about history but allows us to make valid predictions about the future. This notion of convergence tells us that there is not one specific event or proof that guarantees that the theory of evolution is real but there exists detailed evidence in many arenas of science that all point to the same conclusion.
Origins Reconsidered provides a methodology of convergence that is critical in making a case for what appears obvious to the thinking individual. Unfortunately, the theory of Evolution requires constant re-proving. Evidence which has been overwhelming for the last 150 years is still subject to "debate" for a contingent large in numbers, who have attempted to erode the credibility of this science by locating little chinks in the over all armor. Briefly, convergence is the making of inductions from classes of facts that may be disparate in and of them selves, and making strong scientific cases for each class. Once that is done the convergence of all of these explanations makes an extraordinary case for the over all objective. In this case the objective is that the theory of evolution is once again, strong and obvious.
The book is written in six different parts that take the reader through an explanation of methodology, through some obvious conclusions and lastly into some speculation about what the future bodes. The authors tell most of the story in clear and sequential ways. Initially part one "In search of the Turkana Boy" is more prosaic and nearly fictional in style. It describes the setting and friendships amongst skilled and intellectual colleagues in search of "Missing link" or at least additional verification of paleo-anthropological evolution. In this section I did worry that I was reading the wrong book; that I was about to endure a book of anecdotes about what life in the anthropological dig would be. Fortunately I did not give up.
Leakey attempts to make a case for how the first humans came about. At what point are those of us who are considered human distinguished from other nearly similar hominoids? Leakey explores aspects of personality that of course include the use of tools but extends the search to the beginning of language, writing, musical instrument making and art to name a few aspects.
He explores the concept of consciousness and morality to further his premise. While many animals have instinctual altruism and show human signs of affection it is the ability to remember things distant and to create an ethical code of morality that distinguishes us from Cro-Magnons and other late near humans.
Leakey furthers his case by addressing evolution itself and the arguments against it. He talks about the arguments and dismisses them succinctly. "In many cases the urge to know surpasses what can be known; questions without answers." Many find this impossible to accept and seek mysticism in its place, extracting meaning where none exists.
Leakey would applaud the fact that mankind has evolved into the most powerful animal on earth but he has no delusions that this is part of a divine plan. There is no predestination in evolution. Mutations occur that are of benefit and help those survive to pass that gene on and improve the species. What has happened in history is only one possible result. There is no inherent superiority in adaptation. Humans have always tried to have a gap between them and animals mainly because of the need to assuage our subjective consciousness.
Origins Reconsidered also discusses how difficult paleontology really is. He uses the problem of distinguishing early hunter/gatherers from scavengers as an example. Both leave their orts in locations that are very difficult to distinguish. At the same time these are very different survivors.
Ultimately Leakey maintains that while currently humans rule the earth it may not always be so, at least not as we understand humans. He sees the future as one wrought with ecological problems. He uses the notion of mass extinction to make his point. He asserts that throughout history there have been many periods of natural mass extinction. Those were precipitated by events such as Ice Ages. He maintains that Biota are fairly resistant to natural disaster. Floods for instances can apparently wipe out some local vegetation but that same biota can revive. Man made ecological disaster is another matter. Leakey's concern is that the current trends toward smog, deforestation and global warming my create a pathos that vegetation cannot withstand.
Leakey and Lewin display very clearly, the science behind their own efforts but they also describe the weaknesses of science in making determinations about what is a human. Those weaknesses are noble when they are ascribed based on sound scientific theory and otherwise when "proven" by only considering results that make one's point.
Leakey may have an axe to grind. He presents excellent scientific evidence but was never trained as a scientist in any field. Of course he is a scion of one of the most prolific of paleontologists; he never received a degree of any sort to lend to his credentials. His skills come from "on the job training" but they are sound. I believe it is rare that an individual can produce sound evidence to back up their empirical claims without the scholarly background, Leakey has done it.
As a non scientist, it is my endeavor to understand evolution from as many perspectives as possible and this is a book that weighs heavily on that purpose.
