Since George Simpson published the original Tempo and Mode in Evolution in 1944, discoveries in palaeontology and genetics have abounded. This volume brings together the findings of today's leading experts in the study of evolution, including Stephen Jay Gould, Ayala, and W. Ford Doolittle. The volume examines early cellular evolution, explores changes in the tempo between the Precambrian and Phanerozoic periods, and reconstructs the Cambrian evolutionary burst. Long overlooked despite Darwin's interest in it, species extinction is covered in detail.
