The origin of modern human and their settlements caused controversy with two different hypothesis. One is ‘Out of Africa’ hypothesis, confirm that all modern humans stem from a single group of Homo sapiens who emigrated from Africa 2,000 generations ago and spread throughout Eurasia over thousands of years. These settlers replaced other early humans (such as Neanderthals), rather than interbreeding with them. The second hypothesis is Multiregional that Homo sapiens is the evolution from Homo erectus, and that evolution took place in many parts of globe independently. Genetic studies and fossil evidence show that archaic Homo sapiens evolved to anatomically modern humans solely in Africa between 200,000 and 60,000 years ago. Hence the ‘Out of Africa’ hypothesis, that modern human stem from Africa is recognized. The human family was born in Africa, and many millions of years passed before we have any evidence that hominids had managed to escape the continent’s confines and went to conquer Asia and Europe. In “The Journey of Man: A Genetic Odyssey,” American geneticist and anthropologist Spencer Wells uses techniques of genetics to prove the theory of humankind’s spread from Africa into the far corners of the world. By using DNA analysis, he analyses the Y chromosome, which differentiates populations of human beings, and had the result that they all originate from genetic Y chromosome known as M168, as humans migrated out of Africa. The study of genetics of Russian Academy of
