May 3, 2014 · The biogenetic law is a theory of development and evolution proposed by Ernst Haeckel in Germany in the 1860s. It is one of several recapitulation theories, which posit that the stages of development for an animal embryo are the same as other animals' adult stages or forms.
Embryology theories of Ernst Haeckel and Karl Ernst von Baer compared. Haeckel advanced a version of the earlier recapitulation theory previously set out by Étienne Serres in the 1820s and supported by followers of Étienne Geoffroy Saint-Hilaire including Robert Edmond Grant.

Mar 11, 2024 · Ernst Haeckel (born Feb. 16, 1834, Potsdam, Prussia [Germany]—died Aug. 9, 1919, Jena, Ger.) was a German zoologist and evolutionist who was a strong proponent of Darwinism and who proposed new notions of the evolutionary descent of human beings. He declared that ontogeny (the embryology and development of the individual) briefly, and ...

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 ( ontogeny ), goes through stages resembling or repre...
Nov 23, 2006 · Ernst Haeckel and comparative embryology. Ernst Haeckel (1834-1919) is both a hero and a villain in the biological community. He was a prominent figure in the late nineteenth-century comparative anatomy community and is famous for his phylogenetic trees, anatomical illustrations, support for evolution, and strong personality.
Jun 16, 2010 · Haeckel aggressively argued that the development of an embryo repeats or recapitulates the progressive stages of lower life forms and that by studying embryonic development one could thus study the evolutionary history of life on earth. Haeckel was born on 16 February 1834 in Potsdam, Germany (then Prussia) to Charlotte Sethe and Karl Haeckel.
Feb 24, 2019 · Still, one important aspect of embryology is the (evolutionary) developmental anatomy of both human and animal embryos. Here, we present a short history of the visualization of Ernst Haeckel’s “biogenetic law” and his “gastraea theory” in biology textbooks from the German Democratic Republic (GDR) between 1951 and 1988.
