caption_attribution_description: English: This file is a redrawn and colored version of a sketchy, colorless diagram from the Journal of Heredity (1921) Volume 12, pg 421. It depicts human body proportions changing as the subject matures. The diagram shows that the head becomes proportionately smaller and the limbs become proportionately longer as the subject matures.

context_page_description: Ontogeny and Phylogeny is a 1977 book on evolution by Stephen Jay Gould, in which the author explores the relationship between embryonic development and biological evolution. Unlike his many popular books of essays, it was a technical book, and over the following decades it was influential in stimulating research into heterochrony, changes in the timing of embryonic development, which had been neglected since Ernst Haeckel's theory that ontogeny recapitulates phylogeny had been largely discredited.
context_section_description: The herpetologist David B. Wake, in Paleobiology, wrote that the topic was "at once so obviously important and so intrinsically difficult" that few people would tackle it. The parallelism that Haeckel noted between ontogeny and phylogeny was, Wake observed, a strong argument for evolution, but hardly anyone dared to discuss it. He called the book very good, and predicted that it would set the stage for "endless research", but found it also in a way unsatisfying, using "undigested theory from ecology to explain what is, as yet, unexplainable. Summing up, Wake calls the book "erudite, important, provocative, and controversial", but noted that it could have been much shorter.
  The embryologist Søren Løvtrup, in Systematic Zoology, noted that the book had two objectives, unexceptionably to gain practice, and "more dubious[ly]", to show that "in spite of the collapse of Haeckel's biogenetic law, the subject of parallels between ontogenesis and phylogenesis is still of importance to biology". In Løvtrup's view, this was because Haeckel's law had been refuted except where evolution had by chance happened to add to the end of development. Gould had little new to report, as people knew half a century earlier that development could be modified at other stages; the book was "a great disappointment." Haeckel could "of course be of historical interest" but Gould had chosen not to research Haeckel's influence. Work on "wrong theories" represented, Løvtrup wrote, "a terrible waste of effort and time, and block[ed] further progress."
  The anthropologist C. Loring Brace, in American Anthropologist, noted that 2 years earlier, E. O. Wilson's Sociobiology had with "woeful ignorance" strayed into anthropology, and Wilson's "bright young colleague" Gould had now done the same thing, possibly making trouble for years to come. Gould was "a wonderful writer, literate, erudite, gracefully witty, and gifted with the ability to present difficult material in a straightforward and easily readable fashion." 
  The bulk of the book was fine, though of no interest to anthropologists. But the tenth chapter, "Retardation and Neoteny in Human Evolution", would "mislead a great many people" who would be unable to make an informed judgement about its conclusions. Gould " tums out to be just as much of a teleologist and progressivist as the scholars of previous generations whom he appraises so effectively. He notes that we associate “cute” features with mammals of higher intelligence, features that show 'the common traits of babyhood: relatively large eyes, short face, smooth features, bulbous cranium. The presence of this complex in ad- vanced adult mammals argues for neoteny' (Gould p. 350)." In Brace's view, "Gould's main thesis founders between the Scylla of mosaic evolution and the Charybdis of Darwinian theory." Brace concluded that Gould had provided "nothing more useful than the vision that human form can be understood by regarding 'man' as an overgrown retarded child."
  James Gorman, in The New York Times, wrote that the book was rich but not easy to read; it was primarily for biologists, with long and precise arguments in technical language; a simpler account of the same topic was to be found in Gould's essay "Ever Since Darwin". Gorman called the book scholarly, entertaining and informative, expressed "with clarity and wit".
  The zoologist A. J. Cain, in Nature, called it "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." It was a "massive book", excellently illustrated with often surprising examples, covering both the history and a functional interpretation of heterochrony. Cain found it refreshing to find someone who had a good word for Ernst Haeckel, and who did not "treat Charles Bonnet as a stupid monomaniac" but who brought out the relationship "between acquired characters and recapitulation in the work of the American neo-Lamarckians".
