(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 ...
For most of our evolutionary history—for most of the time anatomically modern humans have been on Earth—we've shared the planet with other species of humans. It's only been in the last 30,000 years, the mere blink of ...
