For me, stone age is the most productive in the history of human evolution. The Stone Age is usually divided into three separate periods--Paleolithic Period, Mesolithic Period, and Neolithic Period--based on the degree of sophistication in the fashioning and use of tools. This is when most people used stone for toolmaking. Stone tools have been evolved at this age and was made from a different variety of stones mostly natural stone such as sandstone, granite, and limestone.

This is Peter and I'm new here. My interest: earth science, meteorology, archeology, health science and economy. Hope this is a nice place to stay on for learning and sharing ideas. “Love is not written on paper, for paper can be erased. Nor is it etched on natural stone, for stone can be broken. But it is inscribed on a heart and there it shall remain forever.”
