179 | David Reich on Genetics and Ancient Humanity

Human beings like to divide themselves into groups, and then cooperate, socialize, and reproduce with members of their own group. But they're not very absolutist about it; groups tend to gradually (or suddenly) intermingle, as people explore, intermarry, or conquer each other. David Reich has pioneered the use of genetic data in uncovering the history of ancient humanity: what groups existed where and when, and how they interacted. The result is a picture of churning populations in constant flux, including "ghost populations" that no longer exist today.
