Thomas Hunt Morgan was a Nobel Prize winning American evolutionary biologist, geneticist and embryologist. He developed an early interest in natural history while roaming around in the countryside of Kentucky and later earned his B.S. in zoology. While working for his postgraduate degree at the newly founded Hopkins University he became especially interested in morphology. Although he began his career at Bryn Mawr College his major works were done at University of Columbia. Here he stressed mainly on evolution and hereditary and worked with ‘Drosophila melanogaster’ (fruit fly) in order to find heritable mutations. After years of painstaking work, he was not only able to integrate Mendel's theories with the Boveri–Sutton chromosome theory of inheritance, but also provide irrefutable evidence for it. His discovery of the theory of the chromosome began to be compared with the discovery of Galileo and Newton because it represented a great leap and opened the door for further studies. He won the Nobel Prize in Physiology for his discoveries that explained the role played by the chromosome in heredity.
