I never said it was most likely to have jumped from a bat. We have no way to measure which is more likely, but it strikes me that it isn't highly unlikely to have jumped from a bat. I don't get you "anti-vax" guys. One post is about how the vax was unnecessary, the virus wasn't that bad, the stats were pumped up, etc. Now it's the only way a virus this strong could have happened was in a lab. What lab did previous pandemics escape from? It's a natural process for viruses to mutate in more infectious variants; the virus in question is still doing that.
