The early human tool kit
In Ethiopia, archaeologists have found evidence of toolmaking that dates to about 2.6 million years ago! This ancient “tool kit” included stone cores, hammerstones, and sharp flakes. Early humans knew how to use a hammerstone to strike a stone cobble at just the right angle so that sharp flakes flew off the core. These sharp flakes were then used to cut animal hides and butcher meat, while the hammerstone could be used to crack open nuts. Other evidence from Kenya indicates that earlier episodes of tool making may date back to 3.3 million years ago.
