Complex stone tools from 160,000 to 170,000 years ago found in China

The Levallois method of making stone tools was used in India 172,000 years ago:

Rather than chipping flakes off a stone to create a tool, Levallois techniques work on the stone so it is the flakes themselves that become the tools. This enables several tools to be made from a single stone.

Until recently, it seemed that the Levallois revolution didn’t spread east to places like China until much later – about 40,000 years ago – but that idea is now being questioned. Bo Li at the University of Wollongong, Australia, and his colleagues have just confirmed that Levallois-style stone tools recovered from Guanyindong cave in south China are between 160,000 and 170,000 years old. Colin Barras, “Complex stone tools in China may re-write our species’ ancient history” at New Scientist

Interesting that Barras uses the term “ancient history” in describing the find’s significance. As more and more blanks are filled in, evolution becomes more of a history and less of a theory.

Here’s a guess: More light will be shed on some questions but many popular ones will recede in importance. If, for example, someone wants to claim that early man’s brain was shaped by sexual jealousy, well, it’s an opinion the commentator is entitled to but it won’t really have the same status as a trove of newly discovered artifacts. It will be more like having a similar Big Theory about the Sumerians or the Biblical patriarchs.

I would think that any human chipping away at a stone would notice if the chips coming off had sharp edges that would be useful and then use them accordingly. To say that some humans used the stone left behind while others learned to use the chips seems silly. Depending on the type of stone and his purpose in doing the chipping, I can't help but think he would use whatever worked best. Moreover, how can scientists accept that a pile of stone chips is clear evidence of human tool making (AKA Intelligent Design), but that 6 giga-bytes of complex code in our cells is not evidence of ID?

TDC comments: aligns well w/ The ice ages post Mabul impacts year, from 1657 anno mundi till 1996, so instead of big gaps we have reasonable spacing/placement as we departed the ark, hunted and came from the East (including China) to found Ur in Mesopotamia (The plain of Shinar) so about 4k YA not 165k . reference RCCF framework for understanding science.
