Anytime.
do you think this could be due to the low population levels?
Not really. I don't think their populations would be all that much lower than early on in our species history. Certainly no lower than the Neanderthals who never seemed to have a large population to being with.
yet we see some pretty dynamic changes in the Erectus line.
Not really... a hand-ax is a hand-ax is a hand-ax. The tools that they were making in the early days are essentially identical to the ones they were making in their last days.
They didn't develop a suite of tools or any regional variations in tools.
Nope. Certainly more advanced than pebble tools, but again they had the hand-ax and they stuck with it. No awls or scrapers... just the hand-ax. The only real variation was in size.
In fact, the hand-axes being used by
H.erectus weren't really much different than those used by the other early Homo species that preceded them. It wasn't until after H.erectus that Homo started using different tools for different jobs.
(fun fact... the quality of your hand-ax may have had a social role as well. A nice one may have made you sexy and/or intimidated rivals. Evidence for this comes from the fact that some hand-axes were impractical as tools due to their size)
Doesn't require language to learn.
I agree to a point
I just think Erectus has been underestimated
Absolutely... these were the first great explorers in our lineage. They were a fantastic people and they totally deserve more respect and attention.
But, we have to be careful not to go overboard. They weren't us... they didn't care for the sick or injured as we do, they didn't bury their dead... that also hints that they didn't have language.
Caring for the sick requires that you be able to ask the other what is wrong and being able to articulate your needs to those who want to help you.
If
H.georgicus is actually
H.erectus georgicus then we have the first evidence of elder care and the case for language in this population grows a bit stronger (at least in this particular population).
There was a great show on TV and I cant recall it, its not the one I first posted. But scientist studied the Brocas area and other ares of language development abd stated Erectus most likely had language. This is what put me on the hunt.
Well, like I said... Broca's area is also key in manipulating objects. So, while it's tempting to use development here to imply language... it's not solid evidence.
IMHO the development in the Broca's area is more likely tied to the development of those wonderful hand-axes.
