To clarify, when you say ‘originated in a laboratory’ do you mean engineered in a laboratory; evolved in an intentionally infected lab animal; or transiently stored in a laboratory?
These are very different hypotheses, but are often conflated.
So far, there is strong evidence that it was not engineered [the spike protein is novel, and not something from the geneticists toolbox], and I haven’t seen any evidence that would favor lab storage or evolution over the much larger wild populations of bats and intermediary animal hosts.
I mean to include all the alternatives that involve the virus passing through a laboratory before spreading to humans; so all the options you list are included. There’s nothing wrong with asking about the probability of a composite event.
