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 given diagram illustrates how the cutting instrument used in the Stone Age period evolved between 1.4 million and 0.8 million years ago.
From an
overall
perspective, it is readily apparent that cutting tool
B
gets sharper and more regular in shape than the earlier tool
A over a period of 0.6 million years.
Firstly
, the front view shows that the edges of tool
A are rough, revealing its earlier stage of development. Whereas
tool
A is comparatively primitive, the smooth edges of tool
B
are clearly more effective as a cutting instrument.
Secondly
, one of the main differences between the tools is shown in the side-view picture. While
tool
A is irregular, in contrast
, tool
B
has a regular, flattened shape. The sharp edge of tool
B
is designed for cutting objects cleanly and easily. Finally
, the back view shows most clearly that tool
A is not only rougher but is also
smaller than tool
B
