when did the prehistoric period start and end
Prehistory Prehistory is the period of human activity between the use of the first stone tools c. 3.3 million years ago and the invention of writing systems, the earliest of which appeared c. 5,300 years ago.
Neolithic Traditionally considered the last part of the Stone Age or The New Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution". It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age). The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals.[a]
Prehistory The period when a culture is written about by others, but has not developed its own writing is often known as the protohistory of the culture. By definition,[1] there are no written records from human prehistory, so dating of prehistoric materials is crucial. Clear techniques for dating were not well-developed until the 19th century.[2]
