This week Spencer and Razib discuss the three great "Pleistocene Paradises" lost to rising sea levels at the end of the last Ice Age: Doggerland, Beringia and Sundaland.

This week Spencer and Razib discuss the Out of Africa theory, Neanderthal admixture, and The Human Revolution with Chris Stringer, Head of Human Origins Research at London's Natural History Museum.

This week, Spencer and Razib do a deep dive into the early history of the British Isles, focusing specifically on the famous "Cheddar Man." Who were the first Brits, and what did they really look like?

Spencer and Razib discuss Charles Darwin's scientific impact on our understanding of evolution, and delve into the mechanism by which selection - both natural and sexual - produces biological change.

15 years after the premiere of the PBS/National Geographic documentary ‘Journey of Man’ and the publication of Spencer’s book, Spencer and Razib talk about the impact they have had on the public’s understanding of genetics and human prehistory. This episode is an hour-long journey through the development of human population genetics, the startling insights provided by the Y-chromosome, and which 2003 population genetic ‘certainties’ have - and haven’t - held up to more recent scrutiny. Destined to be a classic.

Spencer and Razib discuss how geneticists infer ancestry from genomic data, with guest Joe Pickrell - geneticist, founder & CEO of consumer genomics startup Gencove.  Find out why telling you you’re 6% Greek is harder than it seems…

Spencer, Razib and Gareth discuss the past, present and future of consumer genomics, from its early days as a cottage industry to where it goes in 2018 - and beyond.

Razib and Spencer discuss the genetic evidence for the migration of Bronze Age Indo-Aryan steppe nomads across Eurasia, including the political issues surrounding their impact on the Indian subcontinent.

Today, humans are the only species of hominin in the world. 50,000 years ago, however, we were not alone - our cousins, the Neanderthals and Denisovans, walked the Earth with us. Their legacy lives on in our genomes today. Razib and Spencer take us on a tour of how we became a few percent Neanderthal, including an interview with anthropologist John Hawks. (Part 2 of 2)
