The diagram shows the development of cutting tools in the stone age BlBxm
The figure represents the formation of two kinds of tools used for cutting in the stone age. Overall, it can be observed from the given pictures that, tool of type B is much complex in design, whilst tool A is simple from all the views. To commence with, it is depicted that tool of A category have been introduced first 1. 4 million years ago. However, these tools had a sharp cutting edge when it is looked from the side whereas it's front side had a quite uneven and unusual shape. Moreover, tool A is 5 cm long when analysed from back side, it also had an irregular shape and a piercing point in its upper portion. In terms of B tool, it have been discovered 0. 8 million years ago, which is more ancient than the former one. As compared to A, B is slightly large in area, looking from front portion. On the contrary, its side view is too thin as well as honed from both the ends. Likewise A, B is also 5 cm long from its centre when viewed from the back. However, B differs in apperence and by area when compared with A.
