Ayala's Gift, March 17, 2008
This review is from: Darwin's Gift: to Science and Religion (Hardcover)
Ayala's book would be a good introduction to the evolution/Intelligent Design dispute. I wouldn't recommend it for anyone looking for more than the basics though.
The introductory chapter sets up Ayala's contention that evolution is a solution to Christianity's theodicy problem, i.e., how to reconcile the existence of evil with God's omnipotence, omniscience, and benevolence. Ayala's bottom-line is that evil is not part of God's direct design, but rather is a by-product of the operation of the universe. That seems glib to me, but no more so than most of the other theologizing I've seen.
Chapter 2 outlines some of the early arguments from design, from Augustine (late 4th century), to Aquinas (13th century), to John Ray (late 17th century), and finally Paley's 1802 masterpiece.
Chapter 3 outlines the basics of Darwin's theory, particularly its attempts to answer Paley by showing that the appearance of design could be explained in natural terms, without invoking design, as the result of populations of organisms continuously adapting over time to ever-changing environments.
Chapter 4 focuses specifically on evolution's mutation-selection process. Mendel's early discoveries in genetics, sadly ignored for decades, are discussed, as well as a helpful example of how a seemingly impossible evolutionary adaptation, acquiring both resistance to streptomycin and the ability to survive without the key amino acid histidine, is actually so easy that bacteria can accomplish it in less than a week.
Chapter 5 discusses Darwin's main lines of evidence, with some updating of the details. The fossil record, biogeography, and homologies of anatomy and embryology are all briefly sketched.
Chapter 6 reviews the evolution of human anatomy, brain, and culture.
Chapter 7 reviews the "smoking gun" of evolution, molecular biology, which reveals both the unity of life in its reliance on DNA and also the evolutionary pathways that produced the diversity of life forms. Ayala also discusses the molecular clock hypothesis.
Chapter 8 focuses on Intelligent Design arguments. Ayala exposes the "evolution is just a theory" argument and the fatally flawed logic of ID's false dichotomy. (Also see my review of "What's Darwin Got To Do With It.") Ayala also discusses Behe's irreducible complexity (IC) in some detail. Focusing on the eye was probably not the best choice, since Behe himself would probably not classify the eye as IC, but plenty of other ID-advocates do, so it's not a completely inappropriate choice. And Ayala does address ID's classic example of IC, the flagellum, in some detail, so it's a pretty good summary. In particular, the footnotes indicate that a 2007 article on the stepwise formation of the flagellar system is awaiting publication by the National Academy of Sciences. Stay tuned for that!
Chapter 8 also discusses some apparently imperfect designs, oddities, and appalling cruelty in nature. Ayala argues that attributing such things to God is bad theology.
Chapter 9 discusses the perceived -- emphasis on "perceived" -- contradiction between evolution and God, and reviews the history both of educated Christianity's response to evolution and creationist opposition. There is also a brief discussion of some of the key court decisions in cases involving public school education.
Chapter 10 was an interesting discussion of the difference between ordinary induction and the hypothetico-deductive method used in science, with particular emphasis on the importance of testing, something which ID-advocates simply ignore, probably (IMO) because ID doesn't generate any testable hypotheses.
All in all, an interesting, easy to read introduction to some of the key issues and historical background.

The Heart Of The Matter: What Does God Do?, August 8, 2007
This review is from: Darwin's Gift: to Science and Religion (Hardcover)
[reproduced from my blog, EXPLORING OUR MATRIX, at the author's request]
I've been reading several books on evolution, intelligent design, and related subjects, as I seek to decide on representative readings to assign for my religion and science course this Fall. It seems to me that the differences between many viewpoints centers around the question of what God does.
Naturalistic explanations of various things in the world around us have always challenged religious beliefs. The monotheistic God of the Abrahamic traditions continues to have adherents precisely because of the flexibility and all-encompassing character of this concept of God. While Zeus' thunderbolts are now the domain of meteorology rather than metaphysics, the God who is responsible for everything does not disappear so easily. Yet the question must be asked by any religious believer: if you believe in God, what do you envisage God doing, and how?
For Michael Behe, the answer must be that God at least does certain things that set in motion the subsequent evolutionary processes. If everything from the start of the universe can be explained in natural terms, then the concept of God becomes irrelevant and obsolete. For this reason, he spends his most recent book looking for The Edge of Evolution. That he is involved in the unceremonious and begrudging retreat of the God of the gaps further and further into the distant past, and thus further and further away from us, seems not to bother him. Nor does the moral objection to Intelligent Design, which has existed since before Darwin, to which he responds dismissively by stating that "Revulsion is not a scientific argument" (p.239). This is certainly true, but neither is the desire to find something for God to do in the world, in contrast to other things that God doesn't do. Having opened the door to the possibility of design, and thus the inclusion and integration of metaphysics, philosophy and theology into history, Behe then balks at either providing an answer to this moral objection or drawing the apparent implication that the designer is either malevolent or inept.
Much more helpful is Francis Ayala's book Darwin's Gift: To Science and Religion, which is appreciative of arguments such as those of Paley, even when disagreeing with his conclusions. Paley, after all, was working with the best scientific knowledge available in his time. Paley was also an opponent of slavery, which Ayala helpfully notes - it is easy to regard those whose views we disagree with as foolish, particularly authors in the past, and so it is helpful to be reminded of other aspects of their life and work, to remind us to be appreciative of their place in our intellectual history, as well as of the fact that no one alive today will not seem as off target as Paley to some future author writing with the benefit of centuries of hindsight.
Ayala takes completely seriously the evidence for evolution, and the fact that, now that we have DNA evidence, there really is no more doubt about common ancestry and evolution than about the criminals we put away on the basis of the same sorts of forensic evidence. Even Behe acknowledges as much.
The reason why Ayala is able to embrace not just the current state of scientific knowledge, but science as a way of knowing, is that he is able to regard statements about God and statements about the natural world as complementary. The danger here, of course, is that such language can become at best superfluous and at worst meaningless. All our language about God is metaphorical. But we still need at least some clarity if we wish to speak about events in the world, even or perhaps especially those that have natural explanations, as simultaneously 'acts of God'. Does this mean that we really see them as willed expressions of a personal deity, or as sacramental events that, even without outside tinkering, disclose transcendent aspects of the nature of reality to us?
One this is fairly certain. If one lives in North America, Western Europe or Australia, and in a number of other places as well, there is no use deceiving oneself about the character of one's theology. Just as there is no one in any of these places who believes in Zeus in the way that the Ancient Greeks did, so too there is no one who believes in God in precisely the same way that the early Christians did. Our worldview has changed, and attempting to will oneself into an outmoded view of the universe "by faith", even if it were possible (which it isn't), still would not be the same thing as taking that view of the universe for granted.
What is the fundamental difference between the various approaches to theology and to the intersection of religion and science today? The question of what (if anything) God does, and by what means. Answers to such questions will by definition involve metaphor - the challenge is to find metaphors that do justice to our deepest religious experiences and insights in a way that also does justice to not just the present state of our scientific knowledge, but the fact that science's track record suggests that natural explanations of things currently unexplained will one day be forthcoming.

Calm and reasoned, May 21, 2007
This review is from: Darwin's Gift: to Science and Religion (Hardcover)
Professor Francisco Jose Ayala, who once trained for the Catholic priesthood, clearly and concisely explains Darwin's ideas about natural selection and evolution by common descent, concepts as central to our understanding of biology as atomic theory is to chemistry or relativity is to physics, in "Darwin's Gift: To Science and Religion". This is Darwin's gift to science. Ayala also shows how Darwinism is not only compatible with Christianity, but actually helps to glorify the majesty and grandeur of God by contributing to our understanding and appreciation of the material world while absolving God, a perfect being or concept, of the imperfections of His creations. This is Darwin's gift to religion.
Put another way, Darwin reconciled the existence of evil with a benign God by showing how all living things developed naturally, without any supernatural guidance, from previously living things, i.e. evolution by common descent. Darwin may have removed God from the daily workings of the material world, but by doing so, he brought us out of the dark ignorance of supernaturalism into the light of reason and placed God in a more exalted realm at the center of our continued moral strivings and quest for meaning and values.

"Darwin's Gift" brings clear explanations of the science, history and theology of Darwin's revolutionary idea to the general public, who, judging by the results of some recent polls, are sorely in need of some education on all three fronts. Otherwise, at the dawn of the twenty-first century, people with outdated eighteenth century ideas will continue to influence the unwary and ignorant, to the detriment of us all.
