The diagram below shows the development of cutting tools in the Stone Age.
Given is the diagram illustrating data on the changes in the shape of cutting tools during the Stone Age.
Overall, it can be clearly seen that there have been several significant innovations in the bigger size of the tool.
Tool A, which was produced 1.4 million years ago, got a rougher surface than the other one in 0.8 million years ago. From the front view, Tool B had a round water-drop shape compared to the original shape of the rock with little sophisticated curve in Tool A. The tool was much flatter in the side view appearance in the 0.8-year-ago period, which could be seen specifically in the given picture.
The tool later, from the back view, got an enormous size in comparison with the rough piece of rock in tool A. Moreover, it had a rounder shape with more curving lines, which highlighted the fact that there has been a better method to make tools and produced much more effective usage in the later period.
