Considered by many during his lifetime as the most well-known scientist in the world, Stephen Jay Gould left an enormous and influential body of work. A Harvard professor of paleontology, evolutionary biology, and the history of science, Gould provided major insights into our understanding of the history of life. He helped to reinvigorate paleontology, launch macroevolution on a new course, and provide a context in which the biological developmental stages of an organism's embryonic growth could be integrated into an understanding of evolution. This book is a set of reflections on the many...

"Creationism began with the fossil record and there it shall end. Before Darwin, the geological strata with their accompanying fossils formed the first geological theory of life on earth--creationism coupled to flood geology. It was Darwin who stood that theory on its head and showed that, in fact, these same fossils could be used to support his new theory of evolution by natural selection. Ever since Darwin, geology has unequivocally supported evolution and not creationism, and yet today Intelligent Design thrives in popular culture. Here at last we have a definitive collection of...

Although the species is one of the fundamental units of biological classification, there is remarkably little consensus among biologists about what defines a species, even within distinct sub-disciplines. The literature of paleobiology, in particular, is littered with qualifiers and cautions about applying the term to the fossil record or equating such species with those recognized among living organisms. In Species and Speciation in the Fossil Record, experts in the field examine how they conceive of species of fossil animals and consider the implications these different approaches...
