Re-Examining the Out-of-Africa Theory and the Origin of Europeoids (Caucasoids). Part 2. SNPs, Haplogroups and Haplotypes in the Y Chromosome of Chimpanzee and Humans
Our consideration of human haplogroups, and our analysis of the dynamics of the Y-chromosome nucleotide flow from primates to humans during the evolution of genus Homo has shown that a common ancestor of the majority of present day human males, both African and non-African, lived approximately 160,000 years ago. The haplogroup of this common ancestor has been identified as the α-haplogroup, which is equivalent or close to haplogroups A1/A1b in th…
Re-Examining the "Out of Africa" Theory and the Origin of Europeoids (Caucasoids) in Light of DNA Genealogy
Seven thousand five hundred fifty-six (7556) haplotypes of 46 subclades in 17 major haplogroups were considered in terms of their base (ancestral) haplotypes and timespans to their common ancestors, for the purposes of designing of time-balanced haplogroup tree. It was found that African haplogroup A (originated 132,000 ± 12,000 years before present) is very remote time-wise from all other haplogroups, which have a separate common ancestor, named…
Haplogroup R1a, Its Subclades and Branches in Europe During the Last 9,000 Years
This study identifies and describes 38 branches of the haplogroup R1a STR haplotypes which currently exist in Europe or which migrated from Europe to areas in the east, south, and southeast between 6000 and 4500 years before the present (ybp). The study is based on 2471 haplotypes which have been tested for either 67- or 111-markers; it essentially creates a unified robust system, which assembles dozens of R1a-SNPs and thousands of STRs and assig…
Haplogroup R1a as the Proto Indo-Europeans and the Legendary Aryans as Witnessed by the DNA of Their Current Descendants
This article aims at reconstructing history of R1a1 ancient migrations between 20,000 and 3500 years before present (ybp). Four thousand four hundred sixty (4460) haplotypes of haplogroup R1a1 were considered in terms of base (ancestral) haplotypes of R1a1 populations and timespans to their common ancestors in the regions from South Siberia and northern/northwestern China in the east to the Hindustan and further west across Iranian Plateau, Anato…
Mutation Rate Constants in DNA Genealogy (Y Chromosome)
The basic principles of DNA genealogy and the mutation rate constants for haplotypes of Y chromosome are considered. They are exemplified with 3160 haplotypes, 2489 of those in the 67 marker format, with 55 DNA lineages, 11 of them having documented confirmed common ancestors. In total, they cover 8 haplogroups and the time range from 225 to ca. 8000 years before present. A series (including 67 marker, 37 marker, 25 marker, 16 marker mostly of th…
