The theory of recapitulation, also called the biogenetic law or embryological parallelism—often expressed using Ernst Haeckel's phrase "ontogeny recapitulates phylogeny"—is a historical hypothesis that the development of the embryo of an animal, from fertilization to gestation or hatching (), goes through stages resembling or representing successive adult stages in the evolution of the ...
Granville Stanley Hall (February 1, 1844 – April 24, 1924 [1]) was an American psychologist and educator who earned the first doctorate in psychology awarded in the United States of America at Harvard College in the nineteenth century. His interests focused on human life span development and evolutionary theory.
A recapitulation theory of evolutionary development was proposed by Étienne Serres in 1824–26, echoing the 1808 ideas of Johann Friedrich Meckel. They argued that the embryos of 'higher' animals went through or recapitulated a series of stages, each of which resembled an animal lower down the great chain of being .
Rendered obsolete by cytology, discovery of DNA, and atomic theory. Recapitulation theory – the theory that "ontogeny recapitulates phylogeny". [8] See Baer's laws of embryology. Telegony – the theory that an offspring can inherit characteristics from a previous mate of its mother's as well as its actual parents, often associated with racism.
According to the recapitulation theory, such structures should invariably be present in frogs because they were assumed to be at a lower level in the evolutionary tree. Von Baer concluded that while structures like the notochord are recapitulated during embryogenesis, whole organisms are not. [7] He asserted that (as translated):
Haeckel promoted and popularised Charles Darwin's work in Germany [6] and developed the debunked but influential recapitulation theory ("ontogeny recapitulates phylogeny"), falsely claiming that an individual organism's biological development, or ontogeny, parallels and summarizes its species' evolutionary development, or phylogeny, using ...
The recapitulation theory of the atonement is a doctrine in Christian theology related to the meaning and effect of the death of Jesus Christ.. While it is sometimes absent from summaries of atonement theories, [1] more comprehensive overviews of the history of the atonement doctrine typically include a section about the "recapitulation" view of the atonement, which was first clearly ...
Romanes' 1892 copy of Ernst Haeckel's allegedly fraudulent embryo drawings (This version of the figure is often attributed incorrectly to Haeckel.) [1]. Haeckel's illustrations show vertebrate embryos at different stages of development, which exhibit embryonic resemblance as support for evolution, recapitulation as evidence of the Biogenetic Law, and phenotypic divergence as evidence of von ...
