recapitulation of phylogeny

recapitulation of phylogeny Theory, due to E. Haeckel (1834–1919), asserting that ontogeny (the development of the individual) recapitulates or reflects the phylogeny (the evolutionary history of the group). The theory as such has been rejected as not of general applicability, von Baer's ‘biogenetic law’ being sufficient explanation for the observations on which it was based. However, either hypermorphosis or retardation of sexual maturity can result in individual cases of recapitulation.

recapitulation of phylogeny

recapitulation of phylogeny A theory proposed by E. F.Haeckel, asserting that ontogeny (the development of the individual) recapitulates or reflects the phylogeny (the evolutionary history of the individual). The theory as such has been rejected as vague, von Baer'sbiogenetic law providing sufficient explanation for the observations on which it was based. Apart from postdisplacement, most types of heterochrony can result in recapitulation.
