he diagram below shows the development of cutting tools in the Stone Age. Summarise the information by selecting and reporting the main features and make comparisons where relevant.
The diagram demonstrates the evolution of cutting tools from 1.4 million years ago to 0.8 million year ago with 3 angles of viewing: front view, side view and back view.
Both two stones look quite simple, the lengths are about 5 cm and have no handle.
The most significant difference we can see is that from the side view , the tool A is much thicker than the tool B. Compared to tool A ,the tool B is sharper so it can cut thing more conviniently .
From the front view and back view, it is found that the tool B was more polish than tool A. The tool A seems not be changed so much from the origin shape. Thus the cutting funtion of the tool B is much more obvious than tool A.
In conclusion, by looking at the tool B , we can acknowledge that people after 0.6 million year of evolution, they found the way to cut things more effectively with the stone tools.
