What some experts point to as "smoking gun" evidence for it being a manmade virus are the Antiviral Research paper, "The Spike Glycoprotein of the New Coronavirus 2019-nCoV Contains a Furin-Like Cleavage Site Absent in CoV of the Same Clade," published in April 2020, and "Furin, a Potential Therapeutic Target for COVID-19," posted in February 2020.
An anonymous — possibly Chinese — researcher has also discussed the scientific evidence supporting the claim that SARS-CoV-2 is a manmade virus in a blog called Nerd Has Power. The anonymous blogger, who refers to him or herself as "a nobody scientist," points out there appears to be a concerted effort to promote the idea that SARS-CoV-2 is a natural occurrence.
"Not nearly as much literature or other forms of substantial writing have been put out to describe or argue for the other possibility — this virus is man-made," the blogger states in a March 15, 2020, post.
He or she then goes on to explain the importance of the S1 and S2 spike sections of a given virus, and details significant changes found in the S1 portion of the SARS-CoV-2 spike protein, "which dictates which host a coronavirus targets." According to the blogger:
"… the details of these differences and the way the human and the bat viruses differ from each other here in S1, in my and many other people's eyes, practically spell out the origin of the Wuhan coronavirus — it is created by people, not by nature." ...<<<Read The Full Article Here>>>..
