Humans and Neanderthals met often, but only one event matters

Homo sapiens began in Africa but Neanderthals were Eurasian. Any miscegenation would have happened after sapiens left its homeland to embark on its conquest of the world. But the details were unclear.

The article from *The Economist* discusses recent genetic research revealing that humans and Neanderthals interbred multiple times, but only one significant interbreeding event around 47,000 years ago in the Near East had a lasting genetic impact. This event contributed to the Neanderthal DNA found in modern non-African populations, which is estimated to be about 1-2% of their genome. Despite evidence of earlier encounters, these did not leave a genetic legacy. The study, published in *Nature*, utilized advanced computational methods to analyze ancient DNA, showing that while there were many interactions, only this particular event resulted in a significant genetic contribution to modern humans. This finding underscores the complexity of human evolution and the role of chance in genetic inheritance.
