Carl Zimmer Quote
Careful imitation could also explain why hand axes managed to stay so similar to each other for over a million years. If Homo erectus simply looked over old hand axes to guess how to make them, they would have accidentally introduced little variations to their craft. Over a few thousand years, those mismatches would have caused the hand ax to drift far away from its original shape.
