William Ernest CastleBorn 25 Oct 1867; died 3 Jun 1962 at age 94. William Earnest Castle was an American biologist and geneticist who was one of the earliest experimental geneticists. Castle's interest in natural history began as a youth growing up on a farm. From 1897, he was a biology instructor at Harvard. In 1901, he was the first to adopt a variety of the fruit fly, Drosophilia for experiments because of its advantage of quick breeding. He took an interest in Mendel's ideas, extended Mendel's Laws to mammals, and made a connection with Darwin's ideas on natural selection. |
