This suggests that hominids may have had the potential to speak for quite some time.
If so, it raises the possibility that hominids colonised South-East Asia at least two million years ago.

Humans spread out, exterminated the easy prey and probably the competing hominids and populated the livable earth.

The discovery of the remains of at least nine primitive hominids of similar age to the latest find was announced in January.

There are several ways, he thinks, in which female hominids could have boosted their reproductive success by concealing their time of ovulation.
Certainly something must explain the success of Homo sapiens, and the speed with which the species spread and swept other hominids away.
And various other features of hominids' skulls also hint at linguistic ability.
Another project being carried out at the lab is looking at the signals of juvenile development left in the teeth of fossil hominids.
There is some evidence that much older hominids could walk upright.

Americans are possibly the least tradition-bound of hominids, having, in the main, left their sentimental attachments behind in whatever unhappy place they or their families came from.
These stone tools generally consisted of sharp flakes battered off a stone core, but early hominids also did more sophisticated flaking and retouching to sharpen and straighten their blades.
This may sound odd (a theory of mind among hominids?), but as Pagel notes, even two-year-old babies have a greater understanding of what other humans believe than even adult apes do.
These curious hominids lived about two million years ago in an era that scientists consider the crucible of human evolution, when four or more apelike hominid species struggled for survival in Africa.
In six research papers published in Science, an international team described how the hominids had almost-human hands attached to apelike arms, a rib cage that was narrow like an ape's at the top but more humanlike lower down, and a spine that likely had the same number of vertebrae as a human.
