Final answer:
Acheulean technology was restricted to the genus Homo and signifies a more complex toolmaking industry by hominins like Homo erectus, beginning approximately 1.6 million years ago and lasting until 200,000 years ago. The option (A) is correct.
Step-by-step explanation:
According to the current fossil record, Acheulean technology (A) was restricted to the genus Homo. The Acheulean tool industry is known for producing more complex tools, such as hand axes, cleavers, and side scrapers, and these were primarily used by Homo erectus, although other species within the genus Homo, such as Homo heidelbergensis, also used Acheulean tools.
The Acheulean tools first appeared approximately 1.6 million years ago and lasted until about 200,000 years ago. They are characterized by bifacial tools, where both sides were worked, indicating a significant advancement in tool-making skills from the earlier Oldowan tool industry. It's important to note that the Acheulean industry predates the tools of Neanderthals, which belong to the Mousterian tool industry from the Middle Paleolithic. Therefore, option (A) is correct.
