Will this book prove effective?, Juil 24 2008
A society driving an eminent scientist to produce a book such as this is in need of some serious reflective thinking. Prothero's account is not the first such investigation of the clash of science and superstition, but it ranks as one of the most thorough and revealing. Although this is a work of science, it is also a campaign manifesto. The author is eager to expose the fallacies of "Christian" creationism and the duplicitous methods used to foster it. The account may appear strident in some places, but it's too well researched - at many levels - and too well written to dismiss it as purely polemical. Above all, it's a needed work, deserving serious attention.
Evolution, he declares forthrightly, is real. The fossils support it in too many ways to be subjected to doubt. Those who try to erode the idea or dismiss the evidence are mistaken, misdirected and often malicious in their methods. Let there be no uncertainty, the panorama of life is there to see. There are many ways of confirming how animal life has varied over time and Prothero takes us through the analysis tools used to assess the evidence. Radiometric dating should be well understood by now, but creationists still find ways to attempt to challenge it. We learn about taxonomy and cladistics, one of the more arcane aspects of fossil analysis. Molecular analysis, what DNA can tell us about the past is, of course, the fastest growing field in palaeontology.
These tools, applied to the fossils and the environment they were found in, establish the relationships demonstrating that challenging evolution is a meaningless enterprise. Still, the challengers continue to emerge. Prothero's prime target in his account is Duane Gish. The Institute for Creation Research. Gish, who seems to have been around at least since the Noachean Flood, still plods the lecture circuit, where Prothero demolished his presentation at least once. Prothero notes that ICR publications, and Gish's lecture presentations are, at best two decades behind what real research has revealed. Prothero is scathing about those who can write of palaeontology without even gotten their hands dirty doing field work. Even creationism's illegitimate offspring, "Intelligent Design", fares no better in the author's hands. If a "designer" was involved in prompting evolution, It botched the job. Why so many forms of wings, for example, when one or two would suffice? Wings and hands are physically related through what palaeontologists call "homology". As Prothero ably demonstrates, adaptations of similar bone arrangements through time produced wings and hands in various animals. Creationists, who continue to call for "missing links" want the entire process lined out in exquisite detail. That's not likely in the world in which fossils form.
Prothero then describes the emergence of early life. His discussion of the Cambrian Period - once referred to as the "Cambrian Explosion" - and its precursor "The Garden of Ediacara" makes an excellent read. He goes on to the value of invertebrate fossils, most notably the formenifera, in showing the slow, but discernable progress of life over time. Vertebrates, who form the beginnings of our own body plan with a backbone, brain and vision systems, are well depicted. In "The Great Leap Upward", he explains how some of those vertebrates learned to live on land. The lobe-finned fishes led the way, and the recent find of Tiktaalik in Canada, gives much information on how they did it. More significant is the revelation of what body plan changes could lead to dinosaurs, primates, and us.
In his conclusion, "Why Does It Matter?", the author answers the question in two ways. First, he castigates his fellow "Christians" for using deceit and deception in thinking they are reinforcing their faith by deluding others about the validity of evolution. The story of the roots of who we are is too important to dismiss or take lightly. Such tactics must be kept out of classrooms - particularly in the US where Constitutional strictures apply [lucky US!]. Most important of all, he urges, the movement is creating a scientifically illiterate population. In a highly competitive technological world, such a condition bodes ill. Denial of evolution, he notes, reaches into domestic realms such as health care and agriculture. Allowing ideologues influence into the political realm is liable to result bad decisions with long-term effects. How to avoid such ill-considered eventualities? The place to start is here, by reading this book carefully, shedding as much as possible preconceived notions about life and how it works. [stephen a. haines - Ottawa, Canada]
