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 ...
Recapitulation. Haydn's Sonata in G Major, Hob. XVI: G1, I, mm. 58-80 Play ⓘ. [1] In music theory, the recapitulation is one of the sections of a movement written in sonata form. The recapitulation occurs after the movement's development section, and typically presents once more the musical themes from the movement's exposition.
From his observations of these stages in different vertebrates, he realised that Johann Friedrich Meckel's recapitulation theory must be wrong. For example, he noticed that the yolk sac is found in birds, but not in frogs. According to the recapitulation theory, such structures should invariably be present in frogs because they were assumed to ...
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 ...
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 .
Unlike his many popular books of essays, it was a technical book, and over the following decades it was influential in stimulating research into heterochrony (changes in the timing of embryonic development), which had been neglected since Ernst Haeckel's theory that ontogeny recapitulates phylogeny [a] had been largely discredited.
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.
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
