Starting at least 2.6 million years ago, East African toolmakers became tech-savvy road warriors.
Those hominids, perhaps early members of the Homo genus or a dead-end lineage dubbed Paranthropus, traveled up to 13 kilometers from a lakeshore site to obtain and bring back rocks suitable for fashioning into durable stone tools. The finding pushes back the timing of hominids’ long-distance retrieval of any resource by roughly 600,000 years, the scientists report August 15 in Science Advances.
