The illustration provides information about the evolution of stone cutting tools in the Stone Age, which was used by prehistoric men.
In general, the cutting tool had dramatically altered, which became larger during millions of years. Moreover, tool B was more refined than tool A at the shape and sharpness by the craftsmanship of prehistoric men.
According to the graph, 1.4 million years ago, tool A was approximately 10 cm with uneven angles, especially the front view of it, while the back view witnessed a completely different glance. The side view was cut roughly and obtusely.
However, 600000 years later, the cutting tool was advanced significantly from every aspect. It can clearly be seen that tool B was grinded more carefully and witnessed a definite tear-drop shape from the front view. The back and side views were tapered aggressively in order to become a sharper tool. Furthermore, the size was much bigger from both horizontal and vertical axises.
