American geneticist David Райх - one of main revolutionaries in area of study of ancient DNA that for understanding of history of humanity appeared no less important, than archaeology, linguistics and writing sources.In the book Райх shows evidently, how many hidden information about our distant past contains a human genome and as radically genome revolution changes our withstand ideas about modern people. Migrations of our ancestors, their relationships with competitive kinds, distribution of cultures is all appears in the completely other light taking into account data on DNA of fossil remains. The analysis of the scientific opening and researches conduces to the provocative idea: morally, distinctions between present populations are biological reality, however with usual stereotypes she has nothing in common. Question, who we such and from where undertook, it is necessary to put again. An answer is yet in the process of forming, but templates already bulge at the seams.
