Scientists have discovered solid proof that ancient humans weren’t as separate as we once thought—they mixed and mingled! By studying DNA from fossils, researchers found that our ancestors, Homo sapiens, had kids with Neanderthals and another group called Denisovans. This mixing left genetic traces that still exist in modern humans today, like certain immune system traits. Some people even carry DNA linked to Denisovans that helps them adapt to high altitudes. It’s like a prehistoric family reunion, showing how interconnected early human groups were. These findings are rewriting the story of human evolution, proving it wasn’t a straight line but more like a web of relationships!
