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.
