The traditional view is that developmental biology played little part in the modern synthesis, [45] but in his 1930 book Embryos and Ancestors, the evolutionary embryologist Gavin de Beer anticipated evolutionary developmental biology [46] by showing that evolution could occur by heterochrony, [47] such as in the retention of juvenile features ...
Evolutionary biology is the subfield of biology that studies the evolutionary processes ... emerged during the period of the modern synthesis in the 1930s and 1940s. ...
During the 1930s and 1940s population genetics became integrated with other biological fields, resulting in a widely applicable theory of evolution that encompassed much of biology—the modern synthesis.
Conrad Hal Waddington CBE FRS FRSE (8 November 1905 – 26 September 1975) was a British developmental biologist, paleontologist, geneticist, embryologist and philosopher who laid the foundations for systems biology, epigenetics, and evolutionary developmental biology.
The Genetical Theory of Natural Selection is a book by Ronald Fisher which combines Mendelian genetics with Charles Darwin's theory of natural selection, [1] with Fisher being the first to argue that "Mendelism therefore validates Darwinism" [2] and stating with regard to mutations that "The vast majority of large mutations are deleterious; small mutations are both far more frequent and more ...
In the so-called modern synthesis of the early 20th century, between 1918 and 1930 Ronald Fisher brought together Darwin's theory of evolution, with its insistence on natural selection, heredity, and variation, and Gregor Mendel's laws of genetics into a coherent structure for evolutionary biology. Biologists assumed that an organism was a ...
Ernst Mayr wrote that a survey of evolutionary literature and biology textbooks showed that as late as 1930 the belief that natural selection was the most important factor in evolution was a minority viewpoint, with only a few population geneticists being strict selectionists. [6]
In biology, evolution is the process of change in all forms of life over generations, ... In the 1930s and 1940s, efforts were made to merge population genetics, ...
