Biography

Theodosius Dobzhansky was a prominent geneticist and evolutionary biologist who played a pivotal role in shaping modern evolutionary synthesis. Born in Nemyriv, Ukraine, in 1900, Dobzhansky emigrated to the United States in 1927, where he would go on to make significant contributions to the field of genetics. His work integrated the principles of Mendelian genetics with Charles Darwin’s theory of evolution by natural selection, thus bridging a critical gap in biological sciences. Dobzhansky is best known for his work in population genetics, particularly his studies on fruit flies (Drosophila) which provided empirical evidence for the process of natural selection acting on genetic variation within populations. His most famous publication, “Genetics and the Origin of Species” (1937), is considered a cornerstone in evolutionary biology and helped to establish the field of population genetics. Throughout his career, Dobzhansky held various academic positions, including at Columbia University and the California Institute of Technology. He was a member of numerous prestigious scientific societies and received many awards for his contributions to science, including the National Medal of Science in 1964. Dobzhansky’s legacy continues to influence contemporary evolutionary biology, and his famous dictum, “Nothing in biology makes sense except in the light of evolution,” remains a guiding principle in the life sciences.
