My guest today is Razib Khan. Razib is a population geneticist, writer, and entrepreneur. He is a prominent voice in the realm of genetic genealogy, where he illuminates the interplay of genes, history, and culture. His writing has been featured in the New York Times, India Today, the National Review, and his scholarly work is cited in many scientific journals. Razib also has a very interesting Substack called "Unsupervised Learning". In this episode, we talk about commercial genetic testing companies like 23andMe. We talk about the genetic histories of regions like Russia, China, Ashkenazis and Madagasy. We also talk about the Indo-Aryan connection. We talk about whether race is a social construct. We discuss the concept of epigenetics and so-called inherited trauma. We talk about what Cleopatra really looked like and more. I hope you all enjoyed this conversation as much as I did.
