New Merch: Lindsay Nikole DROP. https://freddytylerpaul.com/collections/lindsay-nikole-drop In this final episode of The Evolution of Us series, Lindsay Nikole talks about one of the most fascinating and mysterious topics in human evolution ghost populations. These are ancient hominin species we've never found fossils of, yet their DNA quietly lives on inside us. From the discovery of the Denisovans through a tiny finger bone, to unknown archaic populations hiding in West African and Amazonian genomes, this episode explores what our DNA reveals about the hidden chapters of human prehistory and how these ancient genes are still affecting our health, cognition, and biology today.
