S1/S2 Furin Polybasic Cleavage Site
Dr Peter Daszak, President of the EcoHealth Alliance, inadvertently may have provided indications of its true origin….
Sellins article is presented in the wionews link:
“There is conclusive scientific evidence, however, that COVID-19’s receptor binding domain within the spike protein is structurally closest to that of pangolins (scaly anteaters), not bats, and it was the result of a recombination, not convergent evolution.
“Yet, pangolins have been ruled out as the intermediate host for COVID-19.
“Even Dr Ralph Baric in a March 15, 2020 interview, beginning at the 27:40 time point, stated unequivocally, that pangolins were not the source of COVID-19:
“Pangolins have over 3,000 nucleotide changes – no way they are the reservoir species [for COVID-19], absolutely no chance.”
It is, therefore, logical to conclude that the recombinant event resulting in a pangolin receptor binding domain within a bat coronavirus backbone must have occurred in a laboratory, in a manner similar to the experiment conducted by Ralph Baric and Zheng-Li Shi in 2015.”
Is this a round about way of stating:
1. COVID-19’s receptor binding domain is closest to the pangolin’s. (Pangolin would provide the most suitable backbone for COVID-19.)
2. Daszac says Baric has demonstrated the ability to insert a GOF spike protein into a backbone.
3. Baric’s statement that pangolins were in no way the (natural evolution) source of COVID-19
4. Therefor, COVID-19 was a lab creation.
???? The article continues:
“Furthermore, COVID-19’s S1/S2 furin polybasic cleavage site, a distinctive feature widely known for its ability to enhance pathogenicity and transmissibility in coronaviruses, does not appear in any of 45 bat, 5 human SARS, 2 civet, 1 pangolin and 1 racoon dog coronaviruses, that have S1/S2 junction structures otherwise identical or nearly identical to COVID-19.
“There is no credible scientific evidence that the furin polybasic cleavage site evolved naturally, although the methods for artificially inserting such cleavage sites are well-established.”
