But ancient - DNA sequencing is beginning to shed some light on the issue.11 For example, by comparing a human HAR sequence with the HAR sequence of an archaic hominin, researchers can estimate if the HAR mutated before, after, or during the time period of our common ancestor.12 This approach has revealed that the rate at which HAR mutations emerged was slightly higher before we split from Neanderthals and Denisovans.3, 13 As a result, most HAR mutations are millions of years old and shared with these extinct hominins (but not with chimpanzees).
