Final answer:
Stone tools provided advantages in versatility, hunting, and increased efficiency and specialization in tasks for our ancestors.
Step-by-step explanation:
Stone tools provided several advantages to our ancestors. One advantage was their versatility - they could be used for cutting, scraping, chopping, and butchering meat. Stone tools also allowed our ancestors to hunt and kill animals more efficiently, as they could be hafted and used with increased force. Additionally, the development of more advanced stone tools, such as Acheulean tools and blade tools, led to increased efficiency and specialization in tasks like carving, engraving, and shaping materials like bone and antler.
