The results of four related studies pertaining to the genome of SARS-CoV-2 will be presented. Initially, all available good quality sequences (2790) available at the end of March 2020 at the GISAID database were grouped on the basis of sequence variations into 13 nominal major haplogroups (H1-H13). Highly reliable TAG identifying variations were defined for these, and their distributions among various countries and world regions were reported. Subsequently, all available sequences (74922) of viruses sequences retrieved from individuals infected in June 1 to November 15 of 2020 were analyze, and the findings of this period were compared to the findings of the early stage of the COVID19 pandemic. The potential political signals of these findings will be discussed. The results of the third study, which is the most important, is reflected in the title of the talk. The fourth study was an analysis on the genome sequences of various virus strains designated as Variants Of Concern (VOC), including omicron.
