Anthropology is the study of humanity; the study of human populations, of culture and of language.
In May 2010 it was estimated that the world's population was 6.8 billion. So where did we all come from? A common ancestor? The fossil record shows this doesn't it?
Well, no, it doesn't ...
In his book "The Making of Mankind" Richard E. Leakey states,
‘Biologists would dearly like to know how modern apes, modern humans and the various ancestral hominids have evolved from a common ancestor. Unfortunately, the fossil record is somewhat incomplete as far as the hominids are concerned, and it is all but blank for the apes. The best we can hope for is that more fossils will be found over the next few years which will fill the present gaps in the evidence.’ The author goes on to say: ‘David Pilbeam [a well-known expert in human evolution] comments wryly, “If you brought in a smart scientist from another discipline and showed him the meagre evidence we’ve got he’d surely say, ‘forget it: there isn’t enough to go on’.”. The Making of Mankind, Michael Joseph Limited, London, 1981, p. 43
A popular idea about the origin of mankind is referred to as "Out of Africa", meaning that the entire human population originated in East Africa. The hypothesis is that man's origin is the place where we find the most genetic diversity. However, this is not necessarily true, simply because people are nomadic. According to the Bible, human settlers originated from Babel (in modern day Iraq) and then dispersed across the Earth following the Tower of Babel episode described in Genesis 11. The names and nations of Noah's descendents are described in Genesis 10. The fact that there is a high variation in DNA within Africa simply means that the majority of the gene pool went south from Babel and settled in Africa.
