The graphs below show the development of the cutting tools made by stone, one 
was made 1.4 million years ago, and the other was made 800 thousand years ago, 
viewing from back view, front view and side view. Summarize the information by 
selecting and reporting the main features, and make comparisons where relevant. 
The given diagram illustrates the cutting stone tool and how it was advanced, from 1.4 
million years ago to 800 thousand years ago. It can be clearly seen that the stone tool was 
improved into a sharper and better one, over the years.
The stone tool made 1.4 million years ago was more rounded at the top and bottom edges. 
From the front and the back view of the tool it is clear that the diameter in the middle was 
almost 5 cm and towards the top and bottom, it was around 3 cm wide. The side view shows 
that the tool was wider in the middle, with a diameter of around 3 cm and it tapered 
towards the top and the bottom ends. The back of the stone had fewer cuts than the front 
and they were also not very fine.
800 thousand years ago, this tool developed into a sharper, more refined tool. In the front 
and the back view it can be seen that the maximum diameter of the tool was the same as in 
the older tool, but it was more towards the lower side. The bottom tapered into a 1 cm point, 
but the top tapered more sharply into a 1 cm point. The side view makes it clear that it was 
much lesser in width (1.5 cm) than the older tool. The stone was more chiseled than the 
previous one. 
Overall, it can be observed that the tool was improved over the years to a more refined and 
finer cutting tool.
