"This article aims to reconstruct the history of ancient R1a1 migrations between 20,000 and 3,500 years ago (rb). Four thousand four hundred and sixty (4460) haplotypes of the R1a1 haplogroup were considered in terms of the baseline (ancestral) haplotypes of R1a1 populations and time intervals to their common ancestors in regions from southern Siberia and northern/northwestern China in the east to Hindustan and further west through the Iranian Highlands, Anatolia, Asia Minor and to the Balkans in Europe, including Central Asia, southern India, Nepal, Oman, the Middle East, the Comoros Islands, Egypt, etc. along the way. This study supports the theory that haplogroup R1a arose in Central Asia, apparently in southern Siberia and/or neighboring regions, about 20,000 years ago. No later than 12,000 years ago, R1a1 carriers were already in Hindustan, then traversed Anatolia and the rest of Asia Minor apparently between 10,000 and 9,000 years ago, and around 9,000-8,000 years ago reached the Balkans and spread eastward across Europe to the British Isles. On this migration route or earlier, the carriers of R1a1 (or the parent, higher haplogroups) developed the Proto-Indo-European language and took it with them on their journey to Europe. The earliest traces of the language, from the passage of R1a1 carriers through Anatolia, have been collected by linguists and dated to 9400-9600-10,100 years ago, which largely coincides with the DNA genealogy data described in this work. At the same time that carriers of the sister haplogroup R1b1a2 began to populate Europe after 4800 BC, the R1a1 haplogroup moved into the Russian Lowlands around 4800-4600 BC. From there, R1a1 migrated (or moved as part of military expeditions) south (Anatolia, Mitanni and the Arabian Peninsula), east (southern Urals and then northern India) and southeast (Iranian Highlands) as the historical, legendary Aryans. The haplotypes of their direct descendants are strikingly similar to as many as 67 markers of modern ethnic Russians, Poles, Ukrainians and Belarusians. Today, most people with the European R1a1 genotype live in Eastern Europe, mainly in Russia (up to 62% of the population) and Poland, Ukraine and Belarus (up to 55% of the population in the latter three countries). Detailed reports on their haplotype branches and distinct SNPs (characteristic mutations in DNA) will be discussed in future publications." - btw. add from myself that derivatives of haplogroup R1a1 are also common among Brahmins, i.e. white Hindus who are the dominant caste. The genome of the Brahmins has diverged significantly from ours as a result of the penetration of Denisovan genes into their population. Among the Brahmins, the exchange of genes was small and quickly stopped by the imposition of a caste system. Although small, it took place and affected only their populations - no Europeans have the genes of the Denisovans, it is the genes present in Asia, Australia, North and South America. It is from these genes that some of the differences in appearance, behavior, brain function arise. Remember! Brahmins are the nearly white inhabitants of northern India, not the dark-skinned Dravidians living in the south (who have up to 6% of Denisovan genes, accounting for 99% of Indians immigrating to Europe, with an average IQ of 75).
