3 unusual facts about recapitulation theory


Recapitulation

Recapitulation theory, a scientific theory influential on but no longer accepted in its original form by both evolutionary and developmental biology, namely, that the congruence in form between the same embryonic developmental stages of different species is evidence that the embryos are repeating the evolutionary stages of their ancestral history

Recapitulation theory

More recently, several art historians, most prominently musicologist Richard Taruskin, have applied the term "ontogeny becomes phylogeny" to the process of creating and recasting art history, often to assert a perspective or argument.

The first formal formulation was proposed by Étienne Serres in 1824–26 as what became known as the "Meckel-Serres Law", it attempted to provide a link between comparative embryology and a "pattern of unification" in the organic world.


Adolescence

Evolutionary biologists like Jeremy Griffith have drawn parallels between adolescent psychology and the developmental evolution of modern humans from hominid ancestors as a manifestation of ontogeny recapitulating phylogeny.

Evolutionary developmental biology

An early version of recapitulation theory, also called the biogenetic law or embryological parallelism, was put forward by Étienne Serres in 1824–26 as what became known as the "Meckel-Serres Law" which attempted to provide a link between comparative embryology and a "pattern of unification" in the organic world.

Homo habilis

Evolutionary biologist Jeremy Griffith has drawn parallels between H. habilis and the psychological developmental evolution of modern humans as a manifestation of Ernst Haeckel's theory of ontogeny being a summarised recapitulation of phylogeny, suggesting elements of the phenotype of H. habilis relate to early adolescence (12-13 years of age) in modern humans.
