The Acheulean handaxe was the most common tool of early humans, but we still don’t know what the heck they used it for. LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Acheulean handaxe: large, chipped stone objects which represent the oldest, most common, and longest-used formally-shaped working tool in human history. - Microscopy: the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye. - Microlith: small stone tool usually made of flint or chert and typically a centimeter or so in length and half a centimeter wide.
