He compactly expressed the basis for a cultural recapitulation theory of education in the following claim, published in 1861, five years before Haeckel first published on the subject : G . Stanley Hall used Haeckel's theories as the basis for his theories of child development.

His is also remembered for disputing the veracity of Ernst Haeckel's drawings of embryo, which had been used as justification for the development of recapitulation theory and for his identification of a germinative zone within the developing vertebrate metencephalon that he later termed the rhombic lip.

I've gone over a number of these textbooks, and what you typically find at worst is a figure of the Haeckel diagrams for historical interest with an explanation that rejects recapitulation theory; more often what you find are photos or independently redrawn illustrations of the embryos ."

Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ( " ontogeny recapitulates phylogeny " ) claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species'evolutionary development, or phylogeny.
25.
This theory applied to both vertebrates and invertebrates, and also stated that higher animals go through embryological stages analogous to the adult stages of lower life-forms in the course of their development, a version of the recapitulation theory later ossified in the statement " Ontogeny recapitulates phylogeny " of Ernst Haeckel.
26.
This is one of the reasons it wouldn't have made much different if Darwin had actually read Mendel ( the other is that Darwin's concern with heredity was based more in his understanding of embryology and recapitulation theory than it was in the strict division of somatype and genotype that we now consider requisite for thinking about heredity ).

As they copy-pasted mathematical content from one article to another [ http : / / en . wikipedia . org / w / index . php ? title = Hyperbolic _ Dehn _ surgery & diff = prev & oldid = 498386481 and then in the edit above, as Recapitulation theory, made a claim that this showed competence in mathematics.

It has also been claimed that certain former pieces of evidence for evolution which are now considered out-of-date and erroneous, such as Ernst Haeckel's 19th-century comparative drawings of embryos, used to illustrate his recapitulation theory ( " " ontogeny recapitulates Jonathan Wells criticizes biology textbooks by alleging that they continue to reproduce such evidence after it has been debunked.

With different formulations, including the early "'Meckel-Serres law "', recapitulation theory has been applied and extended to several fields and areas, including the study of language ( its origin ), religion, biology, cognition, and mental activities, anthropology, education theory Recapitulation theory is still considered plausible by some researchers in fields such as the study of the origin of language, cognitive development,
