Neanderthals are known to have had physiological differences from Homo sapiens, including thicker bones and defined brow ridges, as in this model.Credit: Mike Kemp/In Pictures via Getty Two genetic changes in the genomes of Neanderthals contributed to the extinct hominin’s characteristic robust physique — and the differences persist in modern humans. The variants make carriers
