The diagrams below illustrate the early tools from 1.4 million years ago and 800,000 years ago. Summarise the information by selecting and reporting the main features and making comparisons where relevant.
The provided pictures compare the tools of old times from the period of 1.4 million years and 0.8 million years ago.
Looking from the overall perspective, it is readily apparent that although length(in cms) remained unchanged, over time, the outer appearance and shape undergo a significant change in terms of smoothness and sharpness.
To begin with, 1.4 million years ago, all the views of the early tools were highly uneven and asymmetrical, as shown in the first figure. Also, the front view of the 5cm stone was quite thick as compared to its back view. By contrast, the side view turned thinner at the top, compared to the bottom view.
Turning to 800,000 years ago, a dramatic change in the tools made them more sophisticated and symmetrical in look. The front and the back view shaped like an even water drop with a beautiful design on top of it. Also, the side view looked more sharpened, thin, and improved, perfect for cutting purposes.
