Made nearly two million years ago, the Lower Palaeolithic Olduvai Stone Chopping Tool is the first known technological invention - the first example of the fashioning and use of a tool. Found in an early human campsite in Olduvai Gorge, Tanzania, it is scientifically dated to be 1.8 million years old. A harder stone was used to knock flakes off both sides of this piece of dark volcanic lava, intersecting and causing a sharp cutting edge. The tool was then used to chop trees and cut meat from animals, or smash bones for marrow fat - an essential element of early human diet.
‘Picking it up, your first reaction is it’s very heavy… it fits into the palm of the hand… I could perfectly effectively cut meat with this.’
