The supplied diagrams provide information on the improvement of hunting tools during Stone Age for the period of 0.6 million years. Overall, the diagram depicts the changes in shape and size of the instrument.
As can be seen, the tool which was used 1.4 million years ago has slender front view in comparison to the latter tool. Whereas, it is opposite in case of side view. The side view of tool B is more than a half slender as compared to Tool A, with the top more pointed and sharp.
Tool B, the improvised form of Tool A, has flat and smooth body all around. But one thing that didn’t change was the height of the tool, which is almost the same in both of the tools.
The material used for Tool B seemed different than Tool A. The weapon used 1.4 million years ago, has a rough and flaky body, whereas, its developed form has a shiny and smooth texture.
