Humans and their ancestors are notoriously messy, but of all the things they leave on the ground, what survives the longest is rocks. In this episode, we take a look at the origins and development of (arguably) the first technology in history, stone tools, and what the Near Eastern archaeological record can tell us about them. From that specific example though, we also take a look at how hominins gain and hold onto knowledge generally, and how that knowledge builds on itself into something entirely new.
