The diagram below the development of cutting tools in the Stone Age
Summarize the information by selecting and reporting the main features and making comparisons where relevant
The illustration highlights the advancement of Stone Age cutting tools by contrasting one made 800,000 years ago with its predecessor dating back 1.4 million years.
Overall, it is obvious that the earlier tool A looked so simple, while the later tool B was more complex. Major differences might be found in their shape, size and tips.
Looking at the diagram in more detail, the 1.4 million-year instrument was characterized by crude surfaces and rough edges. It was approximately 8 centimeters in length and had a small tip which was sharp when viewed from the back but fairly blunt in case of the front. The width of the edge was narrow, only about half that of the front.
Tool B, however, indicated a more innovative and elaborated manufacturing process, it was around 10 centimeters. The tip was more skillfully sharpened and the surface became smoother. The front view and backside looked like quite a drop of water and a triangle, respectively. This is no change made to the shape of the slide view.
