(Phys.org) —Fossil Homo jawbones found at Dmanisi in the Republic of Georgia have different shapes. Previously, scientists were unable to explain the reason for their diversity. By comparing the Dmanisi mandibles to jawbones ...
The ancestor of all creatures with jaws and a backbone was not a sleek, shark-like beast but a toothless, armoured fish, said a study Wednesday that rewrites Man's evolutionary history.
