Homo erectus ergaster is an extinct chronospecies of the genus Homo that lived in Southeastern Africa during the Early Pleistocene, between 1.9 and 1.4 million years ago. Originally thought to be its own species, Homo ergaster, which means "Working Man", in the 1980s it was discovered that it was actually the African variant of Homo erectus, hence the new name. Ergaster is notable for many reasons: it was the first hominid to use Acheulean (pear-shaped) hand-axes as well as many other stone tools that were far more advanced than the stone tools of its predecessor Homo habilis. It's been suggested that ergaster was also the first hominid to harness the power of fire and the use of language, an important stepping stone on the road to true sapience.
Is the pear-shape as in... 2D or 3D? Like... I get a sharp-pear shaped axe, but I can also see the 3D version as a blunt instrument you can just whack shit with.
So im actually just curious how come with evolution at least for us we only have the very basic version and the complex final version us? Like i dont understand wouldnt we have like more middle groups and why did the first evolution stick around over the more evolved ones
There is no final version. Conditions always change; adapt first or die.
We can barely help ourselves from nuking our own fucking species. There was a time when various hominoids existed around us, but now we're pushing so far back we've isolated wild mountain gorillas. Do you really think we're going to save them from what happens next? I wish we could, but dudeman supporting his family through poaching one; where it can net him ten years of financial peace, is going to disagree; especially when compared to the alternative.
