Step-by-step explanation:
Stone tools were used as percussive tools to break bones in order to extract marrow and nutrients. Percussive tools such as the Acheulean and Mousterian stone tools evolved over time, with Acheulean hand-axes replaced by more sophisticated Mousterian tools that were more efficient and could be used for a variety of purposes, including scraping leather and cutting meat. The techniques for creating these tools, such as lithic reduction and shaping stone cores, reflected advancements in human technology and significantly impacted food acquisition and preparation throughout prehistory.
