The figure delineates the front view, side view and back view of the prehistoric rock tools of two distinct periods from 1. 4 million years ago and 800000 years ago.
Overall, 1. 4 million years ago the tools used were unpolished and irregular shaped whereas in 0. 8 million years ago there has a tremendous change in tools, which was smoothed and sharpened.
As is seen, 1. 4 million years ago, the evolution of tools had an improper pattern that seems to be used directly after etched from rocks. Whereby, the top and bottom edges were rounded. Moreover, the front and back view depicts an irregular form of stone carving with numerous cracks and bulging. Besides that, the side view shows the thickness of the tool which is unevenly dispersed. That is, the top and bottom were tapered while the middle portion was wider. Furthermore, the length of the tool from the crest to the centre was being 5 cm.
On the flip side, the developed version of the tool in 0. 8 million years ago as compared to past tools. The newer tool was highly progressive with sharper top edges and a smoothly curved bottom. Apart from this, the front impression which resembles a teardrop was chiselled with precision for procuring a polished touch. Moreover, the back portion was etched to obtaining an almost similar front view. In addition, the side views Ostended the exact picture of the tool, which was scrapped for obtaining glossily, from the top having a sharped tip, enlarged middle portion and toward the bottom it's narrowing. However, the length of the diameter was kept as same as in the past tools as 5 cm.
