Tempo and Mode in Evolution Genetics and Paleontology 50 Years After Simpson

Since George Gaylord Simpson published Tempo and Mode in Evolutionin 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 colipropagated for 10,000 generations, a physical map of Drosophilachromosomes, and evidence for "hitchhiking" by mutations.National Academy of Sciences Staff is the author of 'Tempo and Mode in Evolution Genetics and Paleontology 50 Years After Simpson', published 1995 under ISBN 9780309051910 and ISBN 0309051916.
