Y-chromosomal ancestors: on the problem of genetic and genealogical nomination

Abstract

The article deals with the problem of the nomination of patrilineal contiguities determined on the basis of genome-wide sequencing of the male sexual Y chromosome. As a result of the detection of irreversible mutations (single nucleotide polymorphisms), it becomes possible to name our distant ancestors using SNP marker indices. Having previously justified the method of "sniping as naming", we have increased the nominative retrospective on the reconstruction of phylogenetic and genealogical lines. Thanks to the use of index names of Y-chromosomal mutations, it was possible to indirectly fill in the proper names of those neighbors who lived earlier in the preserved archival and documentary fund of genealogical sources. We are talking about onomatization as a process of resurrecting the names of ancestors whose genetic traces appeared in our Y chromosomes in the form of snip mutations, in fact attributing a specific male progenitor, who for the first time had an irreversible neutral ONP. The DNA molecule, like a biological document, contains information about our origin hundreds of thousands of years deep, being a genetic cemetery of lucky ancestors. The more human Y chromosomes are sequenced, the more names of proper male ancestors will be reconstructed on the Y-haplodreve. Despite the fact that the nomenclature of SNPs is constantly changing, including due to the synonymization of designations depending on developers and laboratories, the fact of nominative reconstruction of our phylogenetic neighbors through large-scale genome-wide sequencing remains immutable. On the example of the genetic-genealogical (genealogical) reconstruction of the author's patrilineal line, the prospects of a comprehensive (interdisciplinary) study of human patrilineal kinship are shown.
