Yuri Filipchenko

Yuri Aleksandrovich Filipchenko, sometimes Philipchenko was a Russian entomologist who coined the terms microevolution and macroevolution, as well as the mentor of geneticist Theodosius Dobzhansky. Though he himself was an orthogeneticist, he was one of the first scientists to incorporate the laws of Mendel into evolutionary theory and thus had a great influence on The Modern Synthesis. He established a genetics laboratory in Leningrad undertaking experimental work with Drosophila melanogaster. Theodosius Dobzhansky worked with him from 1924. Filipchenko is also known for his work in Soviet eugenics, though his work in the subject would later result in his public denunciation due to the rise of Stalinism and increased criticisms that eugenics represented bourgeois science.
