Genetics has radically transformed our understanding of prehistory over the past two decades, revealing everything from the existence of brand-new, unknown species to interbreeding between Neanderthals and our human ancestors. I talked to geneticists Spencer Wells and Razib Khan, two of the world's most knowledgable communicators on genetics and prehistory, to get a sense for how things have changed.
It's rare for public intellectuals to talk about things they've gotten wrong, but geneticist Razib Khan is an exception. He recently published list of 28 things he's changed his mind about in the last decade, not just in genetics, but in other fields of science, politics, society, and religion. Julia interviews Razib about some of the items on the list -- why did he change his mind, and what lessons does he feel he's learned from his past errors?
