The article discusses the pivotal role of animal resource incorporation into hominin diets, highlighting innovations in tool-making using animal bones. Associated with the development of stone tools around 2.6 million years ago, these practices imply significant technological advancements and social learning in hominin evolution. Sparse evidence from the Lower Pleistocene shows initial uses of unshaped bone fragments for foraging. However, more sophisticated shaped bone tools appeared later in the Middle Pleistocene across Eurasian sites, further suggesting an adaptive shift in hominin cultures driven by these technological advancements.
The advent of bone tools, shaped through knapping, marked a significant evolutionary milestone for Pleistocene hominins, expanding their adaptive strategies in a carnivore-dominated ecosystem.
Research indicates that by 2.6 million years ago, hominins began using stone tools to process animal carcasses, showcasing early technological innovation and social learning.
