DNA genealogy is a new scientific discipline that appeared about ten years ago and connected the pattern of mutations in human DNA with the origin of the person himself, the times and directions of ancient and not so ancient migrations, historical events that left a mark on the DNA of descendants. This A book for those who want to understand the basic concepts of DNA genealogy. But instead of explaining in “plain text”, as in textbooks, the author explains these concepts using specific examples of misconceptions and by answering questions. The perception is much better this way. The interested reader should also imagine who and how deliberately distorts, falsifies, distorts the quite clear provisions of DNA genealogy and its conclusions. DNA genealogy does not at all replace historical sciences, and does not pose such a task. It reveals new data that was not previously known. Thus, DNA genealogy, together with historians, archaeologists, linguists, and ethnologists, recreates a more correct picture of the ancient world. As a result, the genre of the book turned out to be unusual. This is a textbook on DNA genealogy, and a series of illustrations about the achievements of DNA genealogy, its discoveries and discoveries in recent years, and tearing off the masks of liars and provocateurs who are clearly hindered by DNA genealogy.
