Hi, Yuri makes a few mistakes in this. 1) Chimeric viruses (copy and paste) are what scientists make in the lab. They take a piece of one virus and paste it into the genome of another, en masse. This is very different from what SARS-2 is, which is more accurately described as a "mosaic" (lots of little changes all over the genome). This is much much more difficult (if not very close to impossible in the case of SARS-…
Deigin has said explicitly elsewhere that if SARS-CoV-2 arose from a lab accident, he believes it arose from manipulation of a novel, unpublished virus collected by the WIV from nature. This makes any arguments based on distance from existing, published viruses irrelevant. RaTG13 was such a virus (collected 2013, published post-pandemic), but it's very unlikely to be the ancestor for the reasons that you note. No one…
SARS-CoV-2, by contrast, is not among any of the sequences published by the WIV over the years.
