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 a leading 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.
Since George Gaylord Simpson published Tempo and Mode in Evolution in 1944, discoveries in paleontology and genetics have abounded. This volume brings together the findings and insights of today's leading experts in the study of evolution, including Ayala, W. Ford Doolittle, and Stephen Jay Gould. The volume examines early cellular evolution, explores changes in the tempo of evolution between the Precambrian and Phanerozoic periods, and reconstructs the Cambrian evolutionary burst. Long-neglected despite Darwin's interest in it, species extinction is discussed in detail. Although the absence of data kept Simpson from exploring human evolution in his book, the current volume covers morphological and genetic changes in human populations, contradicting the popular claim that all modern humans descend from a single woman. This book discusses the role of molecular clocks, the results of evolution in 12 populations of Escherichia coli propagated for 10,000 generations, a physical map of Drosophila chromosomes, and evidence for "hitchhiking" by mutations.
This is a new and completely rewritten edition of the well-known text Microfossils (first published in 1980) covering all the major microfossil groups, with information on taxonomy, phylogeny, ecology and palaeoecology. particular attention is given to the uses of microfossils in environmental reconstruction and biostratigraphy numerous line and half-tone illustrations emphasis on practical applications of micropalaeontology only student-friendly micropaleontology text available
The planktonic foraminifera have, for over forty years, been recognised to be the most valuable stratigraphic indices for marine sediments of Late Cretaceous and Cenozoic age. However, their evolutionary origins in the Jurassic and their development, morphological evolution and systematics in the Early Cretaceous have, until now, been poorly understood. This book illustrates for the first time all the published taxa known from the Jurassic, and clarifies and corrects their taxonomy. The taxonomy and stratigraphic distribution of the Early Cretaceous planktonic foraminifera are also revised, and all of the published species are illustrated, using the type specimens. The systematics of the Early Cretaceous forms are clearly set out, both for species and for genera: their evolution is explained as well as the ecological importance of the morphological changes they have undergone. Moreover, by analogy with the Recent Globigerinacea the palaeoenvironmental significance of these Early Cretaceous taxa is discussed. The book deals with 136 species belonging to 26 genera, five of which - Compactogerina, Haeuslerina (of the Jurassic), Lilliputianelloides; Claviblowiella and Planohedbergella (of the Cretaceous) - are new. Range charts are provided, as are extensive keys for the more important genera. Superbly illustrated, with 65 high-quality plates, this work will be an invaluable reference for all micropalaeontolists and biostratigraphers worldwide, with many species illustrated by SEM for the first time. This is the first book to collate all known information on the early evolutionary origins of the planktonic foraminifera.
With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot? Evolutionary Patterns demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development.
