1910-1920
Thomas Hunt Morgan is most famous for his work with fruit flies. He began using the fruit flies in experunebtak evikytuibart studies. Morgan selected for specific phenotype value to determine their selective value. The goal of the experimetn was to determine how heredity influenced evolution. Morgan started to mess with the flies' environment to see if he could induce a new mutation. The white eye mutant, discovered in about 1908, marked the beginning of the most productive Morgan's career. In 1910 Morgan began to find new mutations in the fruit flies. Something in his experiment had worked, and his fruit fly colonies began to throw off mutations at an amazing rate. Robert Kohler calls this the "breeder reactor."
