The answer lies in the fact that communication is a way of interacting. Communication in pre-historic time time was conducted orally and supported by the understanding of signs and pictures which were often used in communication. To let yo 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-hestoric time began with the first existence of human beings in the beginning of the quaternary period, i.e. in the diluvium (pleistocene) period about 3 milion years BC. Pre-historic period in Indonesia ended around the3rd 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 the form of rain period (pluvial period) which was intermitted by dry period (interpluvial).
In the glacial period, the level of sea water had decreased drastically, so many 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 continental Asia, while Sahul Shelf made the islands in east Indonesia united with Australia. That is why the flora and fauna of west Indonesia are similar to 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 oled stone culture (Paleolithicum).
The pleistocene period ended about 10.000 years BC, then it was followed by the coming of aluvium period or holocene period which continues up to now. In this period, the ancestor of today’s human beings appeared – the homo sapiens or intelligent beings.
1. Stone age
This happened before metals were known and cultural tools were mainly made of stone, in addition to wood and bone. The stone age is further divided as follows :
a. Old stone age (Paleolithic)
c. New stone age (Neolithic)
The stone tools of the new stone age (Neolithic) were already sharpened and polished, so they looked smooth and beautiful. Besides, earthenware, woven material, and batik were already known. This period is also called cropping period.
The supporter of this culture was homo sapiens consisting of Mongoloid race (majority) and Austromelanosoid race (minority). Examples of tools of this period are : square axe and oval axe.
2. Metal age
In the metal, people were already able to make tools of metal, in addition to stone tools. People already knew the technique for smelting metal and mould it into tools they wanted. There were two methods of making metal tools, one was by using a stone mould and this technique was called bivalve, while the other way was by using a clay mould and was and this was called ‘acire perdue’.
a. The copper Age
People used copper as a cultural means. This cultural means was only known in some parts of the world. It was not konows in Southeast Asia (including Indonesia).
b. The Bronze Age
In this time, people were already able to mix copper with other metals to obtain a harder metal. The most dominant discoveries were tools made of bronze, so this period was called the bronze age.
c. The Iron Age
In this period, people were already able to smelt iron ore and cast it to make tools they needed. Smelting iron is more difficult than smelting copper or bronze because it needs a higher temperature, +/- 3500° C.
The metal age in Indonesia was dominated by bronze tools, so the period was also called bronze age. There were only a few iron tools invented in this time and most of them were similar to bronze tools in shape. Most of iron tools were invented in the historic time.
It should be noted however, that although the metal age began, it does not mean the stone age had completely ended because in the metal age stone tools still developed, even now they still do. The term metal age is only used to show that in that period, people started to know and use metal tools.
The development of metal age in Indonesia was different from Europe because the metal age in Europe passed 3 phases, they were the copper age, bronze age, and iron age. In Indonesia and also in Southeast Asia, however, there was no copper age, the area only experienced two ages – the bronze age abd iron age which happened almost at the same time.
In betweeen the stone age and metal age, megalithic culture developed, that is a culture that used large stones as tools, and the peak of the culture even happened in the metal age. That is the description of the periodization of pre-historic period archeologically. To better understand the description, please study the chart below :
