What is biogenetic law of evolution?
biogenetic law, also called Recapitulation Theory, postulation, by Ernst Haeckel in 1866, that ontogeny recapitulates phylogeny—i.e., the development of the animal embryo and young traces the evolutionary development of the species.
Who gave biogenetic law?
150 years ago, in 1866, Ernst Haeckel published a book in two volumes called “Generelle Morphologie der Organismen” (General Morphology of Organisms) in which he formulated his biogenetic law, famously stating that ontogeny recapitulates phylogeny.
What themes did Ernst Haeckel use?
The Nazi party, rather unfortunately, used not only Haeckel’s quotes, but also Haeckel’s justifications for racism, nationalism and social Darwinism.
How did Haeckel support his Biogenetic Law with his drawings?
Haeckel supported his biogenetic law with his drawings of embryos during different stages of development. In 1874, his work Anthropogenie included drawings of embryonic fish, salamanders, tortoises, chicks, pigs, cows, rabbits, and humans at different stages of development placed next to one another for comparison.
What did Wilhelm Haeckel’s drawings look like?
In 1874, his work Anthropogenie included drawings of embryonic fish, salamanders, tortoises, chicks, pigs, cows, rabbits, and humans at different stages of development placed next to one another for comparison. Haeckel’s drawings made the embryos of the different groups look almost identical in their earliest stages of development.
Did Haeckel exaggerate embryo similarities?
Franz Keibel, a student of Wihelm His and a professor of anatomy at the University of Strasbourg in Alsace, France, tried to recreate Haeckel’s drawings from his own specimens and concluded that Haeckel had exaggerated the similarity between embryos in his drawings.
How did Haeckel disagree with Darwin about embryology?
Although Haeckel cited Darwin as he proposed the biogenetic law, the two disagreed about embryology and evolution. First, Haeckel interpreted the process of evolution as progressive, following a specified path from lower to higher animals.
