The diagram below shows the development of the cutting tool in the Stone Age.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The diagram indicates how the cutting instruments evolved during the stone age. Overall, it is obvious that over the period, with the human impacts, stones that were used as cutting tools became bigger and more effective in chopping food or dividing stuff.
Initially, the front view illustrates that at an earlier stage, tools tended to be rougher and more comparatively primitive. Therefore, in comparison with Tool A, the edges of cutting instruments 80000 years ago were apparently smoother, and it is clear that it was more efficient as a means of cutting.
Another difference between these two tools is shown in the side view. Although the thickness is similar, tool B had a more well-defined line running from the top to bottom, and it allowed people to hold it with less efficiency. Moreover, due to the back view picture, not only being sharper but tool B is also longer and less rugged.
