After almost 18 months since COVID-19 first came to international attention, and caused a global pandemic, no animal source of the SARS-CoV-2 virus has been found despite an enormous search effort.
Every proposed source such as the Wuhan Seafood Market, Pangolins, Bats, Snakes and processed food imported into China has been thoroughly discredited.
There is zero credible evidence for the theory that SARS-CoV-2 arose naturally in wild animals, however there is huge body of compelling evidence that points to a lab release.
There is very convincing evidence for a smoking gun that points to SARS-CoV-2 being the product of Gain-of-Function genetic engineering that has escaped from the Wuhan Institute of Virology (WIV).
The smoking gun is the make-up of nucleotides in the R codons of the SARS-CoV-2 furin cleavage site. Each codon is composed of 3 nucleotides. There are four nucleotides that are written as A,G,C and U.
