Final answer:
Acheulian tools were more sophisticated and required more skill to create compared to Oldowan tools. Acheulian tools were modified on both sides, resulting in a symmetrical tool with two faces, while Oldowan tools were less modified.
Step-by-step explanation:
The difference between Acheulian technology and Oldowan is that Acheulian tools were more sophisticated and required more skill to create compared to the cruder Oldowan tools. Acheulian tools were modified on both sides, resulting in a symmetrical tool with two faces, also known as a biface. On the other hand, Oldowan tools were typically made by removing flakes from stone cores without much modification.
