DOCUMENT

Acheulean large cutting tools were made across Africa and Eurasia for ~1.5 million years, and show surprisingly little variation for a technology so spatiotemporally vast. One explanation for this puzzling degree of conservatism is that Acheulean tools were not culturally transmitted but rather genetically determined. If this hypothesis is true, then Acheulean tools are more akin to animal technologies such as bird nests than to modern human tools. Here we examine the extent to which the...
