The diagrams depict two stone tools used by ancient humans, dated from two different periods of time: 1.4 million years ago and 80000 years ago.
In general, the shape of the newer tool looks sharply different compared to the older one although their sizes are relatively the same.
Over 1.4 million years ago, the cutting tool was a jagged piece of rock. The front and back surfaces are uneven with many cracks and chipped edges, while looking from the side shows this primal tool has a certain thickness and is slightly curved at the top. However, there is no definable sharp tip or edge.
Compared to the earlier version, the tool from 80000 years ago has a much more well-formed shape. The edges and surfaces had been smoothly polished with one end sharpened to a tip and the other flat, similar to the shape a teardrop or a leaf. Additionally, from its side view, the new tool is visibly slimmer than its older counterpart. In a way, this tool more closely resembles modern cutting tools such as a knife.
