The diagram below shows the development of cutting tools in the Stone Age. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
The picture illustrates the differences between cutting tools 1.4 and 0.8 million years ago.
Overall, over a timespan of 600,000 years, the tool was improved significantly. The tool used 1.4 million years ago was smaller in size and shape than that of 0.8 million years ago. There was also an increase in the tool’s length in a period of 600 thousand years.
Tool A, which existed 1.4 million years before, was not as sharp as Tool B, which was used 0.8 million years ago because the tip of tool B was thinner and the edge was more rounded than that of tool A. The length and width of two tools also had many differences. The length of the cutting tool 800 thousand years ago was longer than the length of the tool 1.4 million years ago. Moreover, the width of the Stone Age cutting tool expanded throughout 0.6 million years.
The front and view of the chopping tool 0.8 million years before changed significantly compared to that of the previous time. The front and back sides of the later tool looked similar to a water drop, whereas that of the older period tool seemed to be rougher.
