HERE IS UR ANSWER:
There is a great diversity of human forms all over the planet (Earth). Earlier black, brown, yellow and white races were thought to be descendants of different species. But after a number of evidences, it is known that all human races belong to a single ancestral species of Homo sapiens. The skin colour of different species developed due to the environmental conditions of that particular area. All the species of human beings have their origin in Africa.
Thousands of years ago our ancestors left Africa while some stayed on. The migrants slowly spread across the Earth, from Africa to Australia, America, Indonesia, etc. They travelled down from Africa to West Asia, then to Central Asia, Eurasia, South Asia, East Asia and so on. They went forwards and backwards separating from each other. They had come into being as an accident of evolution and live there.
