One area of paleoanthropological study involves the eating and dietary habits of hominids, erect bipedal primates—including early humans. It is clear that at some stage of history, humans began to carry their food to central places, called home bases, where it
Line was shared and consumed with the young and other adults. The use of home bases is a
(5) fundamental component of human social behavior; the common meal served at a common hearth is a powerful symbol, a mark of social unity. Home base behavior does not occur among nonhuman primates and is rare among mammals. It is unclear when humans began to use home bases, what kind of communications and social relations were involved, and what the ecological and food-choice contexts of the shift were. Work on early tools,
(10) surveys of paleoanthropological sites, development and testing of broad ecological theories, and advances in comparative primatology are contributing to knowledge about this central chapter in human prehistory.
One innovative approach to these issues involves studying damage and wear on stone tools. Researchers make tools that replicate excavated specimens as closely as possible
(15) and then try to use them as the originals might have been used, in woodcutting, hunting, or cultivation. Depending on how the tool is used, characteristic chippage patterns and 网上学习 共创奇迹! 大家网络 topsage 10/21
