To learn more about history of mankind, it is important to undersatnd some definitions of terms:
The time that is before history can be recorded or written.
A group of people existing in some remote area in the world, even at present times. They live in isolation and do not mix up with other cultures. Their every day habits are very traditional and change is not allowed, it is severely punished. They do not trust progress and live a simple life of early man i.e. the hunter-gatherer.
The history of mankind has gone through many stages of development:
-Old Stone Age
-New Stone Age
Stone Age, the earliest period of human culture, when tools were made of stone, bone, antler, or wood, and before metals were first used. The term “Stone Age” encompasses almost the whole of human existence, because it starts with the very earliest tools detectable in the archaeological record, but ends only a couple of centuries ago in some parts of the world, such as Australia or Polynesia, where metal was not used until the arrival of Europeans.
By the mid-19th century, antiquarians in Europe had established that humans had existed in remote antiquity alongside extinct animals; that the stones which formerly—in Classical and medieval times—had been seen as thunderbolts were actually early tools; and that flaked stone tools preceded polished stone tools in the archaeological record, even though nothing was known of the extent or duration of their periods of use. This “Stone Age”, which preceded the Bronze Age and Iron Age, was eventually subdivided by the British naturalist and politician Sir John Lubbock: in 1865 he coined the terms Palaeolithic (from the Greek palaeo, old, and lithos, stone) and Neolithic (from neo, new) for the periods of flaked stone and polished stone tools respectively.
