I mean it could evolve to be airborne in the wild or in a research lab doing intentional gain of function research (a practice for which funding was temporarily halted by Obama) and hybridization much like has been done at BSL-4 facilities worldwide unchecked including by EcoHealth alliance with bat coronaviruses via US funding at the WIV prior to the Covid outbreak in Wuhan. https://www.science.org/content/article/n…
Why is parent getting downvoted? The lab leak theory is pretty mainstream these days. And gain of function research is 1: real 2: fucking insane and 3: a plausible way we would have a true captain trips style pandemic.
Is it "possible"? Yes, theoretically. But it's not at all trivial, and far down my worry list. It's bit like worrying that sharks are going to evolve wings and start flying around eating people.
