About the book: 2020 / American geneticist David Reich is one of the main revolutionaries in the field of studying ancient DNA, which turned out to be insufficient for understanding human history less important than archaeology, linguistics and written sources. In his book, Reich clearly shows how much hidden information about our distant past the human genome contains and how the genomic revolution is radically changing our established ideas about modern people. The migrations of our ancestors, their relationships with competing species, the spread of cultures - all this appears in a completely different light when taking into account DNA data from fossil remains. Analysis of scientific discoveries and research leads to a provocative thought: apparently, the differences between current populations are a biological reality, but it has nothing in common with the usual stereotypes. The question of who we are and where we came from has to be posed anew. The answer is still in the process of being formed, but the templates are already bursting at the seams.
