    Abstract 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 S1/S2 junction of their spike protein at the same position where the PRRA insertion in SARS-CoV-2 has created a polybasic furin cleavage site. We show that RmYN02/RacCSxxx instead of the claimed...

    Regarding Nicholas Wade (author of https://thebulletin.org/2021/05/the-origin-of-covid-did-people-or-nature-open-pandoras-box-at-wuhan/) I hope he can comment on this article: https://www.sciencedirect.com/science/article/pii/S1873506120304165It was cited in a comment thread at the Bulletin of Atomic Scientists under his article. Is the article in Science Direct propaganda from the CCP?
