The pedigree is the science of the nobility.

Once a special branch of the genealogy was developed for the benefit of the aristocrats. He was involved in gathering information about the history of the noble family and clan. Early genealogies appeared in the most primitive societies.

For dozens of generations, Polynesians from their leader's ancestors can register. And the most ordinary members of the tribe also remember the name of his great great-grandfather and fifteen or twenty or even thirty times.

In the small Toda Indian tribe, every child knows exactly the names of the next seven ancestors. As researcher L. Shaposhnikova says, Toda is surprised that she has not been able to see into her past so far, and is sorry for her, the poor "mother" thing.
