Zhou et al. reported the discovery of RmYN02, a strain closely related to SARS-CoV-2, which is claimed to contain a natural PAA amino acid insertion at the S1/S2 junction of the spike protein at the same position of the PRRA insertion that has created a polybasic furin cleavage site in SARS-CoV-2. The authors support with their findings the theory that the furin cleavage site insertion present in SARS-CoV-2 is natural. Because no nucleotide alignment with closely related strains of the region… 
An open debate on SARS-CoV-2's proximal origin is long overdue
TLDR
The search for SARS-CoV-2's origin should include an open and unbiased inquiry into a possible laboratory origin, given the immense social and economic impact of this pandemic.
Should we discount the laboratory origin of COVID-19?
TLDR
This paper presents a new construct called WIV Wuhan Institute of Virology Transmembrane serine protease (WIV) that has shown the ability to cleavage Furin during angiotensin-converting activity and to bind to Receptor binding motifs.
