Theodosius Dobzhansky

Theodosius Dobzhansky was a prominent geneticist and evolutionary biologist who played a key role in the modern synthesis of evolutionary theory. He is best known for his work on the role of genetics in evolution and for emphasizing that "nothing in biology makes sense except in the light of evolution." Dobzhansky studied how genetic variation within populations leads to adaptation and speciation. His research helped bridge the gap between Darwin's theory of natural selection and the principles of genetics, demonstrating how evolution operates through inherited traits. His contributions laid the groundwork for much of our current understanding of evolutionary biology.
