Evolution: What the Fossils Say and Why It Mattersby Donald R. Prothero
Synopses & Reviews
Over the past twenty years, paleontologists have made tremendous fossil discoveries, including fossils that mark the growth of whales, manatees, and seals from land mammals and the origins of elephants, horses, and rhinos. Today there exists an amazing diversity of fossil humans, suggesting we walked upright long before we acquired large brains, and new evidence from molecules that enable scientists to decipher the tree of life as never before.
The fossil record is now one of the strongest lines of evidence for evolution. In this engaging and richly illustrated book, Donald R. Prothero weaves an entertaining though intellectually rigorous history out of the transitional forms and series that dot the fossil record. Beginning with a brief discussion of the nature of science and the monkey business of creationism, Prothero tackles subjects ranging from flood geology and rock dating to neo-Darwinism and macroevolution. He covers the ingredients of the primordial soup, the effects of communal living, invertebrate transitions, the development of the backbone, the reign of the dinosaurs, the mammalian explosion, and the leap from chimpanzee to human. Prothero pays particular attention to the recent discovery of missing links that complete the fossil timeline and details the debate between biologists over the mechanisms driving the evolutionary process.
Evolution is an absorbing combination of firsthand observation, scientific discovery, and trenchant analysis. With the teaching of evolution still an issue, there couldn't be a better moment for a book clarifying the nature and value of fossil evidence. Widely recognized as aleading expert in his field, Prothero demonstrates that the transformation of life on this planet is far more awe inspiring than the narrow view of extremists.
"Prothero, a geologist at Occidental College (After the Dinosaurs), explains how rich the fossil record has become. His goal is two-fold. First, he wants to demonstrate the wide variety of transitional forms that have been found, many within the past 20 years. Second, he aims to discredit the creationist movement. 'I have tried to document how they routinely distort or deny the evidence, quote out of context, and do many other dishonest and unethical things — all in the name of pushing their crusade.' He accomplishes both of his goals (though he can be repetitious regarding the creationists), and his descriptions of recent research, much of it his own, are compelling. Prothero explains that the Cambrian explosion of life forms was anything but an explosion, and presents the impressive transitional fossils between reptiles and birds, along with striking evidence for mammalian evolution, including the relationship among hominid groups. With good science and some specific rebuttals to creationist arguments, this book demonstrates the importance of paleontology to the study of evolution. 208 illus."

In the grand sweep of evolution, the origin of radically new kinds of organisms in the fossil record is the result of a relatively simple process: natural selection marching through the ages. Or is it? Does Darwinian evolution acting over a sufficiently long period of time really offer a complete explanation, or are unusual genetic events and particular environmental and ecological circumstances also involved? With The Origin of Higher Taxa, Tom Kemp sifts through the layers of paleobiological, genetic, and ecological evidence on a quest to answer this essential, game-changing question of biology.
Looking beyond the microevolutionary force of Darwinian natural selection, Kemp enters the realm of macroevolution, or evolution above the species level. From the origin of mammals to the radiation of flowering plants, these large-scale patternsandmdash;such as the rise of novel organismal design, adaptive radiations, and lineage extinctionsandmdash;encompass the most significant trends and transformations in evolution. As macroevolution cannot be studied by direct observation and experiment, scientists have to rely on the outcome of evolution as evidence for the processes at work, in the form of patterns of species appearances and extinctions in a spotty fossil record, and through the nature of species extant today. Marshalling a wealth of new fossil and molecular evidence and increasingly sophisticated techniques for their study, Kemp here offers a timely and original reinterpretation of how higher taxa such as arthropods, mollusks, mammals, birds, and whales evolvedandmdash;a bold new take on the history of life.
