As part of his research into human origins for a recent book, Dr. Joshua Swamidass, an associate professor of laboratory and genomic medicine, has looked closely at how race has been defined in recent centuries. "If you go back about 150 years ago in science, and 500 years ago in theology, people have been wondering about this idea of polygenesis,” a long-dominant theory of disparate human origins, Swamidass explains. “Many scientists believed that — and that there’s a hierarchy [of races], with Europeans at the top.” Genetic science since the 1960s and ’70s has strongly disproved such ideas, and yet this has led to what Swamidass calls "a hangover of misunderstanding" surrounding terms like "race" and "racism." In this episode, host Sarah Fenske talks with Swamidass about why understanding the ways in which humans thought about race, and were influenced by racism, in the past is perhaps more timely than ever.
