Pleistocene Exchange Networks as Evidence for the Evolution of Language
Distances of raw-material transportation reflect how hominid groups gather and exchange information. Early hominids moved raw materials short distances, suggesting a home range size, social complexity and communication system similar to primates in equivalent environments. After about 1.0 million years ago there was a large increase in raw-material transfer distances, possibly a result of the emergence of the ability to pool information by using a protolanguage. Another increase in raw-material...[Show more]
