SARS‐CoV‐2′s claimed natural origin is undermined by issues with genome sequences of its relative strains

27 May 2021

Abstract excerpt

RaTG13, MP789, and RmYN02 are the strains closest to SARS-CoV-2, and their existence came to light only after the start of the pandemic. Their genomes have been used to support a natural origin of SARS-CoV-2 but after a close examination all of them exhibit several issues. We specifically address the presence in RmYN02 and closely related RacCSxxx strains of a claimed natural PAA/PVA amino acid insertion at the...
