Final answer:
The statement that the Acheulean stone tool complex emerged around 1.6 Mya and is associated with Homo erectus is true. These tools were bifaces and represented an advanced form of toolmaking, demonstrating the cognitive evolution of early human species.
Step-by-step explanation:
The Acheulean stone tool complex did indeed emerge around 1.6 million years ago (Mya) and is characteristic of Homo erectus. This assertion is true and aligns with archaeological findings. The Acheulean tool industry represented a significant leap in stone tool technology. These tools were distinct from the earlier Oldowan tools, as they were bifaces, meaning they were modified on both sides leading to a symmetrical tool. Developed significantly later than the Oldowan tools, the Acheulean hand-axes were widely utilized throughout Africa, Europe, and the Middle East, contrasting to their rare presence in Asia. The emergence of Acheulean tools highlights the cognitive and motor skill advancements of Homo erectus, showcasing a heightened ability to construct complex implements essential for various tasks such as hunting, scraping, and butchering.
