(Phys.org)—Although humans are a single species, not all genetic variation is shared between populations – and the ability to sequence our entire genome has allowed scientists to catalogue mutations that occur in one ...
New research on a 45,000-year-old Siberian thighbone has narrowed the window of time when humans and Neanderthals interbred to between 50,000 and 60,000 years ago, and has shown that modern humans reached northern Eurasia ...
