Final answer:
The tool technology associated with H. erectus/ergaster is primarily the Acheulean tool industry, which includes hand axes, cleavers, and scrapers.
Step-by-step explanation:
Tool Technology of H. erectus/ergaster
The tool technology associated with Homo erectus/ergaster includes the use of Oldowan stone tools and the more advanced Acheulean tool industry. The Acheulean tools, such as hand axes, are characteristic of the technological advancements made by these hominins. They represented a significant leap in the ability to shape and use tools for a variety of purposes including hunting, butchering animals, processing food, and woodworking. The most common biface tool associated with the Acheulean industry was the hand axe, which was shaped to fit the user's hand and served multiple functions. Another significant advancement in the Acheulean toolkit was the cleaver, which had a broad cutting edge and was suitable for hacking wood or butchering animals. The side scraper was another Acheulean tool used to scrape hides for making simple clothing.
It is important to note that these Acheulean tools are predominantly found in Africa, Europe, and the Middle East and appeared around 1.6 million years ago. The absence of these tools in Asia might suggest that the Acheulean industry was not developed by the time Homo erectus migrated there or other materials like bamboo were used instead of stone for tool making.
