A pioneering geneticist and evolutionary biologist, he helped bring Darwin’s ideas together with modern genetics and became one of the key architects of the modern evolutionary synthesis. His writing and research made evolution feel both scientifically rigorous and deeply relevant to how life changes over time.

About the author
Born in 1900 in Nemyriv, in what is now Ukraine, he studied in Kyiv and built his early scientific career around insects before moving to the United States in 1927. He went on to become a major figure in 20th-century biology, working at institutions including Columbia University, the California Institute of Technology, and later the University of California, Davis.
His most influential work showed how genetics and natural selection fit together in real populations, especially through studies of fruit flies. The 1937 book Genetics and the Origin of Species became a landmark of the modern evolutionary synthesis, helping unite fields that had often been treated separately.
He was also known for explaining science in memorable, human terms. His often-quoted essay line, "Nothing in Biology Makes Sense Except in the Light of Evolution," captured the idea he spent his life defending: that evolution is the thread that ties the living world together.
