This study uses ecological niche modeling to reconstruct the palaeodistribution of Neanderthals and anatomically modern humans during Marine Isotope Stage 5, identifying the Zagros Mountains as a potential contact and interbreeding zone.
Analysis of dozens of ancient genomes reveals that close encounters between Neanderthals and humans took place in a narrow time window. The high-resolution analysis also allowed the authors to track when certain Neanderthal DNA sequences appeared in the H. sapiens genome and determine whether they were retained.
