“I think we have abandoned the idea of a family tree for thinking about human populations. I think that that model is just so hopelessly wrong that we actually have to think about new mental pictures to think about our relationships to each other.”

Reich: Unidentified Denisovan fossils are already sitting in East Asian museums
“Well, I think it's almost certainly the case that there has been a fossil record found, and it's staring us in the face in museums all around East Asia. So I think if you go to Southern China, or you go to Southeast Asia, or you go to parts of Russia, you will…”
Reich: Modern human populations are almost entirely products of mass migration
“But what we now know is that that's almost never true, and that the people who live in any one place today are almost always The result of layers and layers of mass migration and population mixture convulsively replacing and changing each population over time,…”
Reich: European ancestry in African Americans is four-to-one male-derived
“African Americans today have about 80% ancestry from West Africans and about 20% ancestry from Europeans with a lot of variation. But the European ancestry in African Americans comes four to one from the male side. So very little of it comes from European wome…”
Reich: India's genetics show sex-biased admixture 3,000 to 4,000 years ago
“If you look in people in India today are the result of a massive convulsive mixture between two groups that occurred around three or 4000 years ago, and we now know that from lots of lines of evidence, including ancient and modern DNA analysis. Now that proces…”
Reich: 70% of the human reference genome comes from one African-American individual
“About 70% of the human reference genome is that of an African-American who had about 50% European and 50% African ancestry. And then the remaining pieces of the reference genome, the remaining about 30%, comes from other individuals, some contributing more and…”
