DNA genealogy is a new science that has recently experienced rapid development in Russia and abroad. Based on its own methodology, it makes it possible today to clarify, specify and even radically change the formulation of questions that historians, linguists and archaeologists are struggling with. In this sense, DNA genealogy helps to lift the veil on many mysteries of antiquity. Who are the Slavs and how are they related to the legendary Aryans? Where did Prince Rurik come from? What secrets does the ancient Russian North keep? How to find out your family and find close and distant relatives? The famous scientist, professor at Moscow and Harvard universities Anatoly Alekseevich Klyosov tried to answer all these questions in his new book. Together with his colleagues and like-minded people, he stands on the threshold of new scientific knowledge that can change our understanding of the past.
