The diagram delineates the differences between prehistoric tools from 1. 4 and 0. 8 million years ago. From overall perspective, it is readily apparent that the earlier tool has less subtle edges while the newer tool is more refined.
Above all, comparing the two tools based on the frontal view shows the sharper tip with more rounded sides of the recent tool. However, the older one seems slightly slender and rough-cut, displaying primitiveness.
In addition, the side view indicates that the 1. 4 million years tool is also thicker and craggy, unlike the smoother 800, 000 years ago one. Lastly, there is a major differences viewed from the back side. The newer tool almost imitate the frontal view and wider on the bottom. On the other hand, the older one has heavily cracked side and uneven shape.
