Final answer:
The stone tools associated with Homo erectus are part of the Acheulean tool industry, more sophisticated than the earlier Oldowan tools, and used for various tasks including hunting and butchering.
Step-by-step explanation:
The stone tools associated with Homo erectus, including specialized hand axes for cutting, pounding, and scraping, are part of the Acheulean tool industry.
The Acheulean tools were more sophisticated and required more skill to create than the earlier Oldowan tools. They were carefully crafted by chipping away smaller flakes of the stone core to create teardrop-shaped hand axes.
These hand axes were highly efficient tools used for a variety of tasks such as hunting, butchering, and scraping hides to make clothing.
