This topic is important because it will assist an anthropologist to analyze the theories of evolution with a better stand. It is also essential since it tells about the origin of humans and it will help in determining the similarities in biological and physical characteristics of the beings in association with their area of origin. It will also help in determining the changes that have occurred in the human beings from their time of existence.
Answer: The author presented an argument supporting the Out of Africa theory which states that today’s human beings evolved basically from Africa and around 100,000 to 200,000 years back. A research was conducted by a group of researchers from the University of Maryland in 2003 in Tanzania. This is an area presenting a population with diverse phenotypic differences. The mitochondrial DNA was analyzed and the changes in their genes were kept constant and the time for their evolution resulted to around 170000 years back which supported the fact of the Out of Africa theory. Two skulls were also discovered from Ethiopia which also upheld this fact that the period of development of today’s beings dates back to around 100000 to 200000 years.
Answer: The author also presented with the Multiregional theory which provides explanation that human beings basically evolved from not just one location but the modern human beings actually originated everywhere around the world and they spread and went distant apart which led to the development of different racial characteristics amongst them. This hypothesis claims that the earliest remains of human beings will not be restricted to one area but will rather be found all around the world and that the recent human beings have evolved long time back that is more than million years back. The author then explained his arguments in favor of the Out of Africa hypothesis with strong evidences to support this theory above the Multiregional
