Random Factors: An Interview with 2017 Thomas Hunt Morgan Medal Recipient Richard C. Lewontin.

The Thomas Hunt Morgan Medal is awarded to an individual member of the Genetics Society of America for lifetime achievement in the field of genetics. It recognizes the full body of work of an exceptional geneticist. The 2017 recipient is Richard C. Lewontin, whose contributions and influence have profoundly shaped the field of evolutionary genetics. As a testament to this legacy, his nomination for the Morgan Medal was cosigned by 160 faculty members from around the world. A student of Theodosius Dobzhansky, Lewontin's early work established the two-locus theory, which laid the foundation for our understanding of linkage disequilibrium. In the 1960s, he collaborated with biochemist Jack Hubby on a method to quantify natural genetic variation using protein gel electrophoresis. This approach helped launch the field of molecular evolution and spurred a great influx of data into a formerly theory-dominated domain. The subsequent contributions of Lewontin and his group helped set the stage for much of modern population genetics and genomics research. As well as this direct impact, Lewontin influenced the field through his guidance and inspiration, as well as through his capacity to spur vigorous but productive debates. His prominent role as a writer and social commentator included highlighting problems with the inference of heritability, concepts of race, and the overemphasis of genetic influences on phenotypes.
