Today in our archaeology lecture, we're examining the tools used by early humans. One key discovery was a hand axe from the Lower Paleolithic period, found in Tanzania. This axe, made of volcanic rock, was likely used for cutting meat and wood. Interestingly, unlike later tools, it was not attached to a handle. Its symmetrical shape suggests the maker had a clear mental template. The surface shows signs of deliberate polishing, which might indicate it was also used for social display, not just practical tasks. So, while its primary function was utilitarian, it may have had symbolic value as well.
