Image of Darwin and Skull
“Seen in the light of evolution, biology is, perhaps, intellectually the most satisfying and inspiring science. Without that light it becomes a pile of sundry facts, some of them interesting or curious but making no meaningful picture as a whole.”

This excerpt from Theodosius Dobzhansky’s 1973 essay “Nothing in biology makes sense except in the light of evolution" helps explain how Charles Darwin’s insight—natural selection—provided the light linking that pile of sundry facts together and enabling prediction. Additional mechanisms of evolution, such as genetic drift and gene flow, have enhanced the explanatory power of evolution theory and the importance of genetics.

Darwin Day

February 12th

On February 12th, we celebrate the birth of Charles Darwin, whose ideas profoundly shaped the 19th century and continue to guide our thinking today. 

Why celebrate Darwin Day?

Evolution is the unifying concept underlying genetics, indeed all of biology, and it provides the explanation for the variation in traits that so fascinated Darwin.
