About the Author

Stephen Jay Gould was Alexander Agassiz Professor of Zoology at Harvard University and Vincent Astor Visiting Professor of Biology at New York University. A MacArthur Prize Fellow, he received innumerable honors and awards and wrote many books, including Ontogeny and Phylogeny and Time’s Arrow, Time’s Cycle (both from Harvard).

Reviews

In Gould’s…new book…Ontogeny and Phylogeny, a scholarly study of the theory of recapitulation, he not only explains scientific theory but comments on science itself, with clarity and wit, simultaneously entertaining and teaching… [This] is a rich book.
*New York Times Book Review*

Steven Jay Gould has given us a superb analysis of the use of ontogenetic analogy, the controversies over ontogeny and phylogeny, and the classification of the different processes observable in comparing different ontogenies. His massive book (in each chapter of which there is as much material as in whole books by other writers) is both a historical exposition of the whole subject of ontogeny and phylogeny, and…a fascinating attempt at a functional interpretation of those phylogenetic alterations that involve changes of timing developmental processes in related organisms.
*Nature*

This [is a] fat, handsome book crammed with provocative ideas… Ontogeny and Phylogeny is an important and thoughtful book which will be a valuable source of ideas and controversies for anyone interested in evolutionary or developmental biology.
*Science*

It is rare indeed to read a new book and recognize it for a classic… Gould has given biologists a new way to see the organisms they study. The result is a major achievement.
*American Scientist*

Gould’s book—pervaded, I should say, with an erudition and felicity of style that make it a delight to read—is a radical work in every sense… It returns one’s attention to the roots of our science—the questions about the great pageant of evolution, the marvelous diversity of form that our theory is meant to explain.
