The Paleolithic was the first era in human history. During it people lived as hunter-gatherers. It is when people learnt to make tools, to use fire, and to clothe themselves. The era produced some amazing artwork, the fabulous cave painting that have been found in Spain and in the Dordogne in southern France.
The word Palaeolithic derives from the Greek â palaios (old) and lithikos (is relating to or composed of stone), which means âold age of the stoneâ or âOld Stone Ageâ.The Palaeolithic period is by far the longest era and was in essence the age of the human evolution.he Palaeolithic period is distinguishable because of their use of knapped tools. Knapped means to chip or break up stone, flint and obsidian with sharp blows to shape them into tools. (Pictured, tools and weapons of the Palaeolithic period).
