Theodosius Dobzhansky

Theodosius Dobzhansky was a Ukrainian-American geneticist and evolutionary biologist whose work was central to the development of the modern synthesis. His book 'Genetics and the Origin of Species' bridged the gap between genetics and evolutionary theory, demonstrating how genetic variation within populations drives evolutionary change. Dobzhansky's research on fruit flies provided empirical evidence for the role of natural selection in shaping genetic diversity. His work remains a cornerstone of population genetics and our understanding of how evolution operates at the level of genes and populations, influencing generations of evolutionary biologists.
