Executive summary: Genetics and the Origin of Species

Theodosius Grygorovych Dobzhansky was among the most influential geneticists of the 20th century. As a child in Russia he collected bugs, and in his early teens he was enthralled by Charles Darwin's The Origin of Species. His studies of Drosophila melanogaster (fruit flies) drew international attention, and in 1927 he came to America. Dobzhansky defined the evolution of new species in biological terms, showing that two separated groups of a particular species became two distinct species at the point where they can no longer produce fertile offspring -- an accidental discovery, as such a split took place in his own laboratory. His 1935 book Genetics and the Origin of Species brought together Gregor Mendel's genetics and Darwin's theory of natural selection, and formed the basis for "modern synthesis" in evolutionary science. As one of the world's most famous geneticists, he spoke out against eugenics and dismissed as silly any suggestion that genetics could justify racial bigotry. His famous 1973 essay titled "Nothing in Biology Makes Sense Except in the Light of Evolution" argued eloquently that theistic creation and evolution are not necessarily at odds.
