It's always so fascinating to me that there were generations of these groups that had some seriously advanced know-how. And I don't think it unreasonable that they could have thrived for hundreds or thousands of years passing on skills of tool making and probably so much more. But I imagine there being huge gaps, Maybe due to climate change or any other competition. How would a gap of 10,000 years effect tool making technology or language for that matter. We can only speculate, but I wonder what social structures were like, and if they built houses or villages.
