Despite the wide and fairly good development of the modern complex of genetic tools, methods and methods for studying human DNA and the genome as a whole, most of the tasks and work on identifying certain genes or genetic combinations of ancient people in the modern representatives of the human race become truly complex. Today, however, the results of an interesting study of genetics specialists from the University of Tartu in Estonia and the University of Padua in Italy, which was based on the need to locate and extract ancient genes from the genotype of several peoples of South Asia, appeared.
In particular, the joint team of specialists studied the genotype of more than 586 people from South Asia and tried using the popular CRISPR-Cas9 gene technique to identify certain gene variants and combinations that theoretically belong to older people who migrated to the territory of South Asia from other places. And they actually managed to discover several genetic markers and variants that are not generally characteristic of the inhabitants of this part of the world — some of which were still active, to one degree or another.
In particular, experts have discovered several genetic combinations that belong to ancient people from Western Eurasia, which indicates two factors at the same time – the South Asian people still keep a fairly large piece of ancient DNA, and are also characterized, as a rule, by a mixed genotype, which somewhat distinguishes them from the rest of the people living both in Asia and in Europe.
Thus, the new study clearly demonstrates the fact that the study of modern genomics and the genotype of people becomes noticeably more interesting, but at the same time, more complex process – however, some individual groups of scientific specialists in genetics suggest that the current results can be positively – doubtful, since they require, in their opinion, additional checks.
