The given diagram presents two cutting tools that were used in the stone age and how they developed over the years. The change is represented by depicting three views of a carved stone namely front, side and back view.
It can be observed that tool A existed about 1. 4 million years ago and with further innovation, tool B was developed which is dated back to 0. 8 million years from now. The different sides of the stone that was cut with tool A show a rather bumpy surface than a more sleek one with toll B. Additionally, the side view for both the tools when compared shows a considerate difference in the shape which is quite thin and sharp when done using toll B.
Despite the dissimilarity, the height of the stone from the point it starts to the peak is constant at 5 centimetres. To summarize, the overall view of the diagram illustrates how with the advent of the new tool over the years, it became easier to cut the stones in a better shape with sharp edges.
