Título:	Theodosius Dobzhansky, Russian-US geneticist
Descrição:	Theodosius Dobzhansky (1900-1975), Russian-US geneticist, in his laboratory with a microscope. Dobzhansky linked Darwin's evolution theory with Mendel's laws of hereditary. He studied the genes of the fruit fly, Drosophila sp, and found a greater variability than expected. He found a high proportion of flies had debilitating genes which were masked by the presence of a dominant 'normal' gene. He showed that the presence of a masked debilitating gene was advantageous as it allowed a population to be more versatile in adapting to a changing environment. Dobzhansky wrote many influential books, including 'Genetics and the Origin of Species' (1937). Photographed in around 1959.
