The Lost Humans Who Are Still Inside Us

The Denisovans were a lost group of ancient humans, discovered from a tiny fragment of a finger bone in a Siberian cave. It didn't look extraordinary, until scientists extracted its DNA. This video follows the Denisovans from Denisova Cave to the people alive today who still carry their genes. You'll see how the bone's DNA matched neither modern humans nor Neanderthals. You'll also see how our ancestors met and had children with Denisovans, possibly more than once, and how a Denisovan gene may still help Tibetans live at high altitude. It also covers Denny, the girl with a Neanderthal mother and a Denisovan father, and the 2025 identification of the Harbin "Dragon Man" skull as Denisovan, which may finally give this lineage a face. Scientists are still debating how the Dragon Man skull should be classified, and which other fossils belong to the lineage. The video separates what is documented from what is still uncertain. 📩Tell us in the comments📩 what surprised you most. 🔔Subscribe🔔 and 👍Like👍 for more stories about our lost human relatives, including the next video🎬 on the Neanderthals.
