Richard Lewontin was an influential American evolutionary biologist, geneticist, and social commentator. A central figure in developing the modern evolutionary synthesis, his pioneering work in molecular evolution and population genetics challenged conventional views on genetic determinism and race. Throughout his career at institutions like Harvard University and the University of Chicago, he was also a prominent critic of sociobiology and a committed political activist, engaging with issues from the Vietnam War to the biological basis of behavior.

Early life and education

Born in New York City to parents of Eastern European Jewish descent, he attended the Forest Hills High School in Queens. He completed his undergraduate studies in biology at Harvard University, earning an A.B. in 1951. For his doctoral work, he moved to Columbia University, where he studied under the renowned geneticist Theodosius Dobzhansky, a key architect of the modern evolutionary synthesis. His PhD dissertation, completed in 1954, focused on evolution and population genetics in the fruit fly species Drosophila pseudoobscura.

Academic career and research

After postdoctoral research, his academic career began at North Carolina State University before he joined the faculty at the University of Rochester. In 1964, he moved to the University of Chicago, where he served as a professor of zoology. In 1973, he returned to Harvard University as the Alexander Agassiz Professor of Zoology and later as a professor in the Museum of Comparative Zoology. His laboratory was a hub for groundbreaking research, attracting numerous students and collaborators who would become leading figures in evolutionary biology. He maintained an active research program even after his formal retirement, continuing to publish and critique scientific ideas.

Scientific contributions

His most famous empirical contribution came from a 1972 study using protein electrophoresis to measure genetic variation in natural populations, demonstrating that species like Drosophila possessed far more genetic diversity than previously assumed. This work helped establish the neutral theory of molecular evolution, developed by Motoo Kimura. In a landmark 1972 paper, he analyzed human genetic variation, showing that the vast majority of genetic diversity exists within, not between, traditionally defined human races—a finding that became a foundational argument against biological determinism and scientific racism. He, along with Stephen Jay Gould, famously critiqued adaptationism and sociobiology, as exemplified in their 1979 critique of The Selfish Gene and the 1979 paper "The Spandrels of San Marco and the Panglossian Paradigm."

Political activism and public engagement

A committed Marxist and member of the SDS, he was deeply engaged in political activism, particularly opposing the Vietnam War and criticizing the role of science in perpetuating social inequality. He was a founding member and frequent contributor to the Boston Review of Books, where he wrote on the interplay of biology and ideology. He co-authored influential critical books like The Dialectical Biologist with Richard Levins and Not in Our Genes with Steven Rose and Leon J. Kamin, arguing against genetic determinism in explanations of human behavior and intelligence.

Awards and honors

His scientific work was recognized with several major awards, including the prestigious Crafoord Prize in Biosciences in 2015, awarded by the Royal Swedish Academy of Sciences. He received the Sewall Wright Award from the American Society of Naturalists in 1994. He was elected a member of the United States National Academy of Sciences in 1968, though he later resigned in protest. He was also a fellow of the American Academy of Arts and Sciences and a foreign member of the Royal Society.

Personal life and death

He was married to Mary Jane Lewontin, a professor of history of science. The couple had four sons and resided in Cambridge, Massachusetts for many decades. An avid musician, he was known to play the cello. He died at his home in Cambridge, Massachusetts from complications of pneumonia, survived by his wife, children, and a lasting legacy that continues to influence debates in evolutionary biology, genetics, and the philosophy of science.
