In 2010, the discovery that early humans and Neanderthals interbred was groundbreaking, revealing a genetic legacy affecting modern humans‘ circadian rhythms, immune systems, and pain perception. However, understanding the gene flow in the opposite direction has been challenging. A new study published in the journal Science on July 12 has shed light on how this intermingling shaped Neanderthals, suggesting multiple episodes of DNA exchange over 250,000 years, thus rethinking the story of
