Simply put, the theory stated that, in the development of an embryo, the whole process of evolution is repeated for a species. Thus ontogeny (development of form) retraces the steps of phylogeny ...
WebBiologists have long debated whether ontogeny recapitulates phylogeny and, if so, why. Two plausible explanations are that (i) changes to early developmental stages are selected against because they tend to disrupt later development and (ii) simpler structures often precede more complex ones in both ontogeny and phylogeny if the former serve as … WebCalled by Haeckel the "biogenetic law, this idea was spread widely by his euphonious slogan, "ontogeny recapitulates phylogeny," meaning that embryonic growth of the fetus in the womb rapidly recapitulates the entire evolutionary history of the species.
