The simplicity is obvious. The press in neutral Spain was not so constrained. The B.1.351 variant first found in South Africa was labeled as Beta, the P.1 variant first discovered in Brazil became Gamma and the B.1.617.2 variant first detected in India is now Delta. The next letters on the list, if it comes to it, which it probably will, are epsilon, zeta, eta and theta. Epsilon refers to the B.1.427 and B.1.429 variants first found in the U.S., Zeta refers to the P.2 variant first discovered in Brazil and Eta refers to the B.1.525 variant initially detected in multiple countries.
Primordial humans could not have created a better evolution system than the one we are currently on.
