ORIGIN OF HUMANS
When they hunted migratory birds and animals humans began to draw food nutrients from a wide range of resources. Animals migrating from places far off were bringing food supplies from areas which lay beyond the range of human groups. H. erectus lived for about 1 million years. About 350,000 years ago appeared another species called the Neanderthal man. They were short, stocky and had powerful physique. Nevertheless they too were not quite human. They used stone tools alright but they did not have language or art. Our environment was shaped by natural forces which in turn shaped our evolutionary path. Nature created different kinds of environments like – hot or cold weather conditions, dry deserts or wet river valleys, sea coasts and mountains. Temporal variants produce changes and modifications some of which led to evolutionary changes.
Modern Humans (Homo Sapiens Sapiens) –
The fully modern humans (homo sapiens sapiens meaning the thinking humans) are present in the Klaiser River mouth caves in South Africa from 120,000 – 60,000 years ago. Theories based on DNA also support the idea of the African origin s of humans about 200,000 years ago. They appeared in the West Asia around 90, 000 years ago. Earlier, our ancestors like the Homo-erectus and the Neanderthals had colonised areas of Africa, Southeast Asia, China and Europe. There were plenty of places in the globe where they had not reached. Siberia, Australia and the whole vast breath of the Americas remained untouched.
