1.6 million years

Definition

1.6 million years refers to a significant timeframe in the context of human evolution, particularly during the early to middle Pleistocene epoch. This period is marked by crucial developments in stone tool technology, notably the emergence of the Acheulean tool tradition, which is characterized by bifacial hand axes and cleavers. Understanding this timeframe helps contextualize the advancements in hominin behavior, migration patterns, and the adaptation of early humans to changing environments.

5 Must Know Facts For Your Next Test
