One of the leading doctors investigating what actually happened over there posted this study, showing that common lab ferrets and shrews are the most likely animal source that was combined with RATG13, which is the closest known bat virus, and existed ONLY in Wuhan.

That’s another theory, sort of in the middle as “semi natural.”
1. Natural: it “just happened” in the wet market.
2. Semi-natural: Scientists did repeated animal species to species experiments until it mutated into a form transmissible to humans.
3. Man-made: RNA frags spliced together to create a “gain of function” novel virus.
My money is on #3, but after #1 is blown, they will probably fall back to #2 as their next cover story.
