BRAINY CHIMPS Some modern chimps have brain surface features that were thought to have signaled humanlike brain
evolution in
hominids from as
early as 3 million years ago, scans suggest.
Rather, they were a much more primitive
hominid population, possibly Homo habilis, whose members lived in, or at least transited, Dmanisi much
earlier than what our accepted chronology of human
evolution indicates.
The basin has been home to important discoveries in human
evolution, including many
hominid fossils and the

He hinted that gestural theory could clear up another mystery about this period as well: why the stone tools of these
early hominids show little
evolution for almost two million years, despite increases in brain size.

Early hominid reliance on carcasses as a source of meat, and the competition with fellow scavengers that went with it, are thought to have contributed to the
evolution of human tool use, cooperative food acquisition, and even language development — the very things that define us as a species!
