David Reich — How one small tribe conquered the world 70,000 years ago

Geneticist David Reich discusses how ancient DNA analysis has revolutionized our understanding of human migrations, population replacements, and prehistory.

There's a second audio track with better sound: English (US). I had no idea how wild human history was before chatting with the geneticist of ancient DNA David Reich. Human history has been again and again a story of one group figuring ‘something’ out, and then basically wiping everyone else out. From the tribe of 1k-10k modern humans who killed off all the other human species 70,000 years ago, to the Yamnaya steppe nomads 5,000 who killed off 90+% of (then) Europeans and also destroyed the Indus Valley Civilization. So much of what we thought we knew about human history is turning out to be wrong, from the ‘Out of Africa’ theory to the evolution of language, and this is all thanks to the research from David Reich’s lab. * Buy David Reich's fascinating book here: amazon.co.uk/Who-Are-How-Got-Here/dp/110187032X 𝐄𝐏𝐈𝐒𝐎𝐃𝐄 𝐋𝐈𝐍𝐊𝐒 * Transcript: dwarkeshpatel.com/p/david-reich * Apple Podcasts: apple.co/3RFuS7b/ * Spotify: spoti.fi/3APeQ3L * Me on Twitter: twitter.com/dwarkesh_sp 𝐒𝐏𝐎𝐍𝐒𝐎𝐑𝐒 * This episode is sponsored by Stripe.
