Thomas Hunt Morgan September 25, — December 4, [2] was an American evolutionary biologist , geneticist , embryologist , and science author who won the Nobel Prize in Physiology or Medicine in for discoveries elucidating the role that the chromosome plays in heredity. Morgan received his Ph. Following the rediscovery of Mendelian inheritance in , Morgan began to study the genetic characteristics of the fruit fly Drosophila melanogaster. In his famous Fly Room at Columbia University 's Schermerhorn Hall , Morgan demonstrated that genes are carried on chromosomes and are the mechanical basis of heredity. These discoveries formed the basis of the modern science of genetics. During his distinguished career, Morgan wrote 22 books and scientific papers. His father had difficulty finding work in politics and spent much of his time coordinating veterans' reunions.

Among other projects that year, Morgan completed an experimental study of ctenophore embryology, ts morgan. Driesch and others thought that development was due to epigenetic factors, where interactions between the protoplasm and the ts morgan of the egg and the environment could affect development.

Since Morgan 'solved the problem of heredity, he was in a unique position to examine critically Darwin's theory of natural selection. Heredity was a central plank of Darwin 's theory of natural selection, but Darwin could not provide a working theory of heredity. Wikimedia Commons has media related to: Thomas Hunt Morgan category.

Deals and Shenanigans. Deutsche Biographie Trove. Norman Angell Great Britain. In Naples and through Loeb, he became familiar with the Entwicklungsmechanik roughly, "developmental mechanics" school of experimental biology. The observation of a miniature-wing mutant, which was also on the sex chromosome but sometimes sorted independently to the white-eye mutation, led Morgan to the idea of genetic linkage and to hypothesize the phenomenon of crossing over. Under Brooks, Morgan completed his thesis work on the embryology of sea spiders —collected during the summers of and at the Marine Biological Laboratory in Woods Hole, Massachusetts —to determine their phylogenetic relationship with other arthropods. In Evolution and Adaptation , he argued the anti-Darwinist position that selection could never produce wholly new species by acting on slight individual differences.

With Fernandus Payne , he mutated Drosophila through physical, chemical, and radiational means. Every summer from to , Morgan and his colleagues at the famous Fly Room at Columbia University moved their research program to the Marine Biological Laboratory.
