DNA genealogy

DNA genealogy, what is it? Is it linked to DNA tests for ethnic groups. Does it relate to the searches that you conduct. Of course, the topic of DNA tests and DNA genealogy itself is interesting. We turn to her to better understand ourselves and understand why we are here. And how our ancestors managed to save their kind. Let’s see what constitutes DNA genealogy.

DNA genealogy is a discipline in population genetics, with the difference that population genetics operates with ethnic groups and macrogroups, DNA genealogy examines each individual and his personal DNA genealogy history of the Y-haplogroup, mt-DNA of the haplogroup, autosomes. Population genetics and human DNA research in the 1990s is primarily the merit of L.L. Cavalli-Sforza, M.W. Feldman, D.B. Goldstein, M.F. Hammer, M.A. Jobling, M. Kayser, P. de Knijff, A. Nebel, M. Nei, A. Oppenheim, O. Semino, M. Stoneking, M. Thomas, P. Underhill, B. Walsh, R.S. Wells, L.A. Zhivotovsky, T.M. Carafet, O. Balanovsky, N. Nasidze and many others.

DNA genealogy, as a tool, gives us the opportunity to find out when a common ancestor lived for a group of haplotypes and, accordingly, for a group of people, how many millennia ago, sometimes up to a century. Often, in the presence of a significant number of haplotypes and snaps, the error does not exceed 10%. That is, if a common ancestor for a group of haplotypes lived 3,500 years ago, then if we have a couple of hundreds of descendant haplotypes (multi-marker “67-marker haplotypes”), we can determine the lifetime of a common ancestor with an accuracy of 3,500 ± 350 years to date. On the timeline, this will set the range into which the lifetime of the common ancestor will fall, and in our case it will be between 3150 and 3850 years ago with a very high degree of reliability.

Genetic genealogy uses DNA tests in conjunction with traditional genealogical research methods. Usually, the success of traditional methods depends entirely on the preservation and existence of documents (for example, census and scribe books, revision tales, etc.). Each person carries a kind of “biological document” that cannot be lost – this is human DNA. Genetic genealogy methods allow access to that part of DNA that is transmitted unchanged from father to son in a direct male line – the Y chromosome.

The Y-chromosome DNA test allows, for example, two men to determine whether they share a common ancestor in the male line or not. DNA tests are not just help in genealogy research – it is a modern, advanced tool that genealogy can use to establish or refute family ties between several people.

The combination of DNA genealogy, linguistics, archeology data will often help to look more broadly at historical issues. DNA genealogy will act as an additional tool, providing genetic data on the carriers of certain archaeological cultures, their male genetic lines. Mutations by which you can restore history in a direct male line will not disappear anywhere even after thousands and tens of thousands of years. They allow you to track the migration of haplogroups and its individual representatives, they allow you to understand the remains of representatives of which haplogroups are in archaeological sites, and what is the relationship and inheritance of archaeological cultures among themselves through their carriers, through people, through specific subclades, to understand the genesis and dynamics of archaeological cultures , add the most important component in establishing the history of the dynamics of human populations by testing both the remains and the alleged carriers.

We can say that DNA genealogy not only helps to identify which ethnic group we belong to, but is also more important for restoring the true history of mankind.

Good luck in finding.
