WebMoreover, many candidates, which loosely follow an 'ontogeny-recapitulating-phylogeny' theme, are not well supported. There are, however, two domains, language and social reasoning, in which human cognition does seem to be unique and which may provide a better way of asking if there are unique patterns to human conceptual change. WebHowever, there are also many cases where ontogeny does not recapitulate phylogeny. For example, the human embryo does not develop gills, even though other mammals such as dolphins and whales do. The theory of ontogeny recapitulating phylogeny is still controversial, and there is no clear evidence that it is true.
Webover evolutionary time, not because increased complexity is always favored, but rather because early states invariably had low complexity, whereas modern ones have both low and high complexity (Gould 1996). However, to our knowledge, Gould did not make any connection between this point and the tendency of ontogeny to recapitulate phylogeny. WebDocsity.
