29.02.2012 - Popis Ötziho genomu uveřejněn v Nature

In the journal Nature was given a message that provides more information about the ice man Ötzi. This is a reading of the entire genome and some of the results are certainly interesting, because they provide quite an interesting insight on the problem of the european population and migration.

The most interesting results are then the following:
1) Genetically, it is Ötzi the closest to the current residents of Sardinia, who are roughly between the modern Europeans, the continental and Ötzim - that is much more distant to modern continental Europeans. It is quite interesting that this confirms the theory that the original inhabitants of Italy and the southern countries of Europe were linguistically and genetically closer than expected, as well, that this is about the original inhabitants of Europe before the advent of the so-called culture zvoncových cups (Bell Beaker Culture). The so-called. paleo-sardinian language was probably very close to iberian languages. This finding also probably will refute the "theory of interruptions" (in English the so-called theory of discontinuity), and it is therefore possible that the focus will be given to theories based on anthropological theses Blumenbacha of 18. century and Sergiho from the beginning of the 20th. the century of the dual origin of the Europeans.
2) This finding also confirms, it seems, a variant that some of the alleles in modern Europeans do not vanish, but on the contrary, that it is the allele from the population, which in Europe přimigrovala.
3) On the other hand, it also seems that Ötzi's ancestors came to the area of northern Italy from the middle East, which has two possibilities of interpretation – either this is about the original inhabitants of Europe who got here after the migration from Africa, and or are not the original inhabitants of this area, but the later migrants.
4) Ötzi's genome also shows the intolerance laktozy, from which one can infer that it was still mainly a hunting population or the early agricultural. However, the results are not conclusive, because the modern inhabitants of Sardinia, this disorder occurs in up to 40-60%.
5) Lyme disease – according to the analysis, it was Ötzi marked for the first person who was infected by this bacteria, however, this figure itself is interesting and shows the total a long time of the occurrence of this infection.
6) a Description of the general appearance and some defects – such as propensity to diseases of the heart, brown eyes, etc.

Thank you Aubimu for the reminder..
