Abstract: Abstract In the spread of SARS-CoV-2, there have been multiple waves of replacement between strains, each of which having a distinct set of mutations. The first wave is a group of 4 mutations that includes D614G. This DG (D614G) group, fixed at the start of the pandemic, is the foundation of all subsequent waves of strains. Curiously, the DG group is nearly absent in early Asian samples but present (and likely common) in Europe from the beginning. Therefore, the European strains would have no time to evolve the 4 DG mutations (0 to 1) if they h...
