On this episode of A Life In Ruins Podcast, we have our good friend and frequent collaborator Stefan Milo on the podcast. Stefan is in the process of researching for a video on human brain size, and we talk about what he has found. Researchers have noted a decrease in brain size in humans within the last 30,000 years. We take a deep dive into how brain size has changed throughout the evolution of the genus Homo and potential reasons for the decrease in brain size. We talk about the possibility of human self-domestication and the theories surrounding it.
