I knew the very first time I heard about it and how crazy it was genetically. There is not way that suddenly happened in nature.
I knew it as soon as I found out the lab was in Wuhan
Dr. Sachun Lin is a “virus hunter” researcher who worked for the US Army Medical Research Center and examined the genome sequence for the Wuhan Covid-19 virus that was published by the Chinese. There are two very important proteins, the N1 protein and the spike (S) protein, that appeared to be suspicious in his opinion.
The N1 protein genome normally evolves as it jumps from bats to other animals or to humans. It determines the viruses “lethality” in the way that it randomizes the structure of quasi species of the daughter viruses to evolve into more infectious variants.
His examination showed that the genome in the Covid-19 is virtually identical with a known SARS bat N1 genome and did not appear to have evolved at all from its original sequence. He estimated the likelihood of this occurring “naturally” as 1:1,000,000,000. This strongly suggests it may have been developed for research purposes and skipped the normal evolutionary path that natural viruses undergo to cross species.
The Spike protein that allows the virus to bind to human cells also appears to have been genetically modified in 4 of its 5 amino acid receptors to fit into human cells. This also suggested to him that it was done intentionally to test a virus species with human cells in anticipation of developing a vaccine or treatment for a future potential outbreak.
His option is still not shared by a consensus of other scientists but it shows why it is necessary to do this at a world wide level with WHO and CDC participation.
