Stone Age humans were picky about which rocks they used for making tools, study finds
Early human ancestors during the Old Stone Age were more picky about the rocks they used for making tools than previously known, according to research published Friday.
Not only did these early people make tools, they had a mental picture of where suitable raw materials were located and planned ahead to use them, traveling long distances.
Interesting, but for some reason this section raised a smile.
“This suggests they’ve got a mental map of where different resources are distributed across the landscape,” said co-author Rick Potts of the Smithsonian's Human Origins Program.
Imagine a Paranthropus conversation along the same lines - "You need a mental map of where different resources are distributed across the landscape" stone chippers say to their apprentices.

I suppose that I must have a mental map of where every pothole is in my 15 mile radius, because I position myself in advance on the road to miss them.
Regarding stone types the stone chipper would not need to know the source. He would just need to know someone who knew. Division of labour.
Doonhamer - I have a similar mental map for our area, the really bad potholes being marked in mental red.
