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.

His father had difficulty finding work in politics and spent much of his time coordinating veterans' reunions. The college required two years of study at another institution and an examination by the college faculty. But while Morgan was skeptical of natural selection for many years, his theories of heredity and variation were radically transformed through his conversion to Mendelism. These discoveries formed the basis of the modern science of genetics. Sturtevant, H.

.

In his retirement, he returned to the questions of sexual differentiation, regeneration, and embryology. Morgan changed his work from traditional, largely descriptive morphology to experimental embryology that sought physical and chemical explanations for organismal development. Byance with his reputation, Morgan held numerous prestigious positions in American science organizations. He published Evolution and Adaptation ; like many biologists at the time, he saw evidence for biological evolution as in the common descent of similar species but rejected Darwin's proposed mechanism of natural selection acting on small, constantly produced variations.
