“Allowing people to live who would not have done so before through in vitro fertilization or through having glasses, despite correcting very bad eyesight, and as a result, it's probable that there are mutations building up that would not have been building up in the past due to the random rain of bad mutations onto our genome. There's an idea that the rate of worsening of the genomic health of human populations is maybe akin a little bit to global warming. It's not getting worse too perceptively on the span of a generation or two, but over the span of a few hundred years, there might be very severe consequences, and so I think that we are in a time of profound environmental and lifestyle change.”

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: The family tree model for human populations is hopelessly wrong
“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: India's genetics show sex-biased admixture 3,000 to 4,000 years ago

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…”
