This brings out the key point of preferential artifact survival. Yet stone tools have allowed us to establish accurate settlement locations because of survival. Yet all those cultures were actually based on fiber.
With fiber you can build semi permanent shelter, gather food and fish. Stone tools become almost an afterthought for the majority of day to day living. Application for hunting is obvious but unnecessary for much else.
Recall also that the rivers really teamed with fish easily taken. This provided a natural store of protein for scant effort. Particular seasons would be exploited.
So yes, the rest of the tool kit needs to be shaken out.
Where Are All the Prehistoric Women and Children?
The prevalence of stone artifacts in the archaeological record, such as this Clovis point from the Dent site in Colorado, has led archaeologists to overemphasize presumably male activities, like hunting. (Credit: DMNS/A448.2)
