Life is known to exist on earth for more than 40 million years. But, the evolution of Man from his ape ancestors has been more recent. This species of primitive man was called the 'Homo Erectus.' Homo-Erectus not only walked straight on his two legs. Other than Homo-Erectus, the 'Neanderthals' have also been found to inhabit what is today modern Europe. But both these species gave way to the new modern man 'Homo-Sapiens'. Pre-historic settlements have been found in France, and some settlements of very early periods hold evidence of even surgeries preformed.Primitive man gradually started learning the use of tools to aid his hunting and food gathering expeditions. This time-period is roughly estimated to have been from around 750,000 years ago, till about 15,000 years ago. This is called the Paleolithic age. It means the 'Old Stone Age'. The evolution of primitive man to his present, modern self can be classified roughly into three periods, Paleolithic, Mesolithic (The middle stone age), and Neolithic or the 'New Stone Age'. During the Mesolithic period, not much of advancement took place and the use of stone weapons remained fairly static. Consequently during the Neolithic period which is roughly from 10,000 years ago to 3500 years ago man mastered the art of carving tools out of stones.Fire was discovered accidentally, during the Paleolithic age. Man had not fully understood fire, though he found it fascinating and useful to protect himself against animals.
