A blockbuster scientific article, published on October 20, 2022, analyzed the restriction sites of COVID-19, which are “cutting and pasting” markers for viruses constructed in the laboratory.
According to the authors, COVID-19 “has the restriction site fingerprint that is typical for synthetic viruses.”
That synthetic fingerprint found in COVID-19 is not a feature of naturally-occurring coronaviruses but is common in lab-assembled viruses.
In addition, the type of mutations that differentiate the restriction sites in COVID-19 are characteristic of engineering, and the concentration of these mutations in the restriction sites is extremely unlikely to have arisen by random evolution.
