The diagram illustrates the evolution of cutting tools in the Stone Age.
In general, it is evident that these stone tools underwent significant developments.
Tool
B was not only larger in size but also
more sophisticated and refined than the previous one.
The cutting tool
used by prehistoric people 1.4 million years ago was quite small, around 7-8 centimetres in length. It was also
crudely made, as can be seen from the illustration, its front and back sides were not symmetrical. Furthermore
, the tool
’s edge was rather blunt because it was not properly sharpened and was quite uneven.
By contrast
, tool
B (0.8 million years ago) shows improved craftsmanship as its two sides were almost identical. It was also
substantially larger than tool
A, around 10 centimetres in length and had a shape resembling a droplet: pointy at one end and widened towards the base. Moreover
, tool
B also
appears more effective as its edge was ground much sharper and smoother than that of its previous version.Submitted by weezel on
