Archaeologists Find Neanderthal Stone Tool Technology in China

[GiqueCee]

1. Is it worth considering...

... the possibility of parallel development of such utensils?
All tools, stone or otherwise, are used by human hands. Shaping the business end of a stone tool for a specific purpose is half the process. The other half is making it fit the hand that employs said tool. That would logically narrow the choice of useful shapes. It would also allow for striking similarities between tools from regions separated by great distances.
On the other hand, we already know that all hominid species had a predilection for wandering. That's how they came to inhabit nearly every land mass on the planet. So it is not unreasonable to suggest that both hypotheses could happen concurrently.
Just a thought.

BTW, I love your posts, Judi Lynn. I always learn something new, and, even in my late seventies, that is my favorite pastime. So thank you for the knowledge you impart!
Have a nice, peaceful Sunday!
