In 1966, at the University of Chicago, Lewontin and John Hubby published two papers that pioneered the use of protein gel electrophoresis to study genetic variation within populations of wild fruit flies. Not only did the technique lay the groundwork for the field of molecular genetics, but it revealed a surprising amount of genetic diversity within the population …
Lewontin was well-known for his critiques of adaptationist programs—the idea that all organismal traits have been “optimized” due to natural selection. Rather, he argued that genetic variation within a population could also be the product of random chance, or due to selection on linked loci on the genome.
He also wrote a seminal 1972 paper in which he argued there is more genetic variation within members of a population of humans than there is between members of different groups, undermining the idea that there is a genetic basis for the idea of race.Stephanie Melchor, “Evolutionary Biologist Richard Lewontin Dies at 92” at The Scientist
