History – About pre history time-The life history of mankind up to the present has not been going on for only a short period of time but it actually started thousands of years ago. The condition of that time and its development up to now have shaped toda’s human beings.
How did people begin to communicate without writing? The answer lies in the fact that communication is a waya of interacting. Communication in pre-historic time was conducted orally and supported by the understanding of signs and pictures which were often used in communication.
To let you know more about it, this chapter will discuss about the development of human beings in pre-historic time.
Pre-historic is a term that refers to the time when written historical records were not available yet. It can be said that pre-historic time started at the same time as the formation of the universe, but the term is generally used to refer to the time when life started on earth. For example, dinosaurs are normally called pre-historic animals and cave men are usually called pre-historic men.
Since there are no written records of pre-historic time, the information about this time is obtained from various fields, such as paleontology, astronomy, biology, geology, anthropology, and archeology.
Periodization of Pre-historic time
Pre-historic time began with the first existence of human beings in the beginning of thequarternary period, i.e. in the diluvium (pleistocene) period about 3 million years BC. Pre-historic period in Indonesia ended around the 3rd to the 5th century AD when some inscriptions were found in Kutai and Tarumanegara.
Pleistocene period was marked by the extension of ice layers on both poles of the Earth (glacial period) and intermitted by the period when the ice melted again (interglacial period).
This condition happened intermittently until four times during the pleistocene period. In tropical regions, this glacial period took te form of rain perod (pluvialperid) which was intermitted by dry period (interpluvial).
In the glacial period, the level of sea water had decreased drastically, so manay seabeds ran dry and became lands. In west Indonesia, the sea floor which got dry was called Sunda Shelf, whereas in east Indonesia, it was called Sahul Shelf The Sunda Shelf made Indonesian Archipelago united with Australia.
That is why the flora and fauna of west Indonesia are similar of those of Asia, and on the contrary, the flora and fauna of east Indonesia are similar to those of Australia. The people who lived in the pleistocene period were homo erectus that supported the old stone culture (Paleoliticum).
