Human evalution

In the beginning, ancient human beings used to live in caves. They had no knowledge and essential instruments to construct houses. But hilly caves, for them, were just like house, which saved them from hot, cold, rain and wild animals.
As far we know, human beings have been living for five lakhs years on the earth. Recently the materials which have been dug out of caves tell one lakh year back history of human civilization. One lakh years ago the human beings were not in the form in which they are seen today. In that time they generally used to be small and little bit fat. Their legs were small heavy, long and stout. Their bodies were covered with dense hairs they had only axe and knife, which had been made of glittering stones. They were learning the art of warming the caves and at that time they began to speak.
Some years ago a group of scientists found a cave in the mountains of Iraq which had systematic history of human beings from the rock age to the present. This is called “Shanidar Gufa”. In this cave Kurd farmers live nowadays. It is a great surprise that human beings have been living in this cave for one lakh years.
Scientists were fortunate that the people who lived there were not fond of neat and clean living. They used to engrave their waste things in the caves. These things have been engraved one after another in piles. Therefore the scientists have dug the floor of the cave and become successful in finding out the history of human civilization of different epoch. It is like he same age we come to know the long history of the earth from the fossils found in crusts of rocks. There are four layers of dusts, soil and sand in this cave. Each layer tells the history of a definite epoch of evolution of human beings.
Outermost layer tells about the present age from seven thousands years back. Pieces of soil utensils stone, grinder of grains, bones of tamed animals show that the people of that time knew about cultivation and taming animals. Second layer is supposed to be twelve thousand years old. This layer doesn’t give any evidence of cultivation and taming animals. Third layer is supposed to be forty thousands years old. There was a difference of thirty thousand years between these two layers. There was found a trace of progress in human civilization at that time. At last the fourth layer of Shanidar Cave takes us a lakh year back history of human beings. It gives a glimpse of primary age of human race in ancient time on the basis of these evidences. There are some drawings of human beings found in the caves which are supposed to be twenty-five thousands years old. Who craved these figures? How did light comes in the dark caves? These mysteries are still unsolved. But probably it can be said that these carving have been done by some unknown artists of Stone Age.
