Prehistory
Prehistory is the term for that period of time from creation until the appearance of the first written records. It is based on a wide range of archaeological, biological, and cultural evidence. Prehistory is not a definite time, rather the period in any society before the use of writing.
Historians describe prehistory as the Stone age which is divided in to two parts, Paleolithic and Neolithic. The Paleolithic age came first, when man harvested wild plants and animals for food. The Neolithic age followed the Paleolithic age. Farming became dominant during the Neolithic age. The dates of these ages are debated, but current anthropological reaearch puts the beginning of the Paleolithic at 2.5 mya, and the Neolithic starting at 10 kya. The Neolithic ended 5 kya.
