What Really Happened When Humans First Met Neanderthals

When Homo sapiens first met Neanderthals 45,000 years ago, it wasn’t an all-out war of extermination. The real story revealed by modern archaeology, ancient DNA, and paleoclimatology is stranger, more nuanced, and deeply human: we fought, we traded, we exchanged pathogens, and we had children together. Today, between 1% and 4% of non-African modern human DNA comes directly from Neanderthals. In this video, we break down what really happened when our two species collided, how ancient interbreeding shaped modern human immunity and health, and why Neanderthals never completely vanished. --- TIMESTAMPS: 0:00 - The Stare-Down: 45,000 Years Ago 0:46 - The Caveman Myth vs. Reality (Shanidar & Cueva de los Aviones) 2:12 - First Contact: The Bacho Kiro Discoveries 3:15 - The Leipzig Revelation: Svante Pääbo & Ancient DNA 4:30 - Did We Fight?
