"On one level, it’s not surprising that modern humans were able to interbreed with their close cousins. According to one theory, Neanderthals, Denisovans, and all modern humans are all descended from the ancient human Homo heidelbergensis. Between 500,000 to 600,000 years ago, an ancestral group of H. heidelbergensis left Africa and then split shortly after. One branch ventured northwestward into West Asia and Europe and became the Neanderthals. The other branch moved east, becoming Denisovans. By 250,000 years ago H. heidelbergensis in Africa had become Homo sapiens. Our modern human ancestors did not begin their own exodus from Africa until about 70,000 years ago, when they expanded into Eurasia and encountered their ancient cousins."
