Since I have probably gotten these questions a thousand times by now, let me just do a quick summary: 1. Is it mutating? Yes. It's normal. 2. Did the epidemic take off in the market? Yes. It's uncontroversial. 3. How do you know? See 1. Apply math. More to come.

Regarding #2, it took off in the market, but my understanding was that evidence pointed to it not originating from there. Is that correct?

A bit of a stretch based on one case? That case could have been infected by casual contact with someone with market exposure and a mild case, on public transit or almost anywhere. That carrier may have recovered and never gone to hospital or been tested. Sampling in market was +.

33% of the cases in December had no known contact with the seafood market (or other wet market) and as you can see on the graph 75% of the earliest 4 cases had no contact with animal markets. So likely the virus was circulating among human population weeks before market outbreak

As far as I know no infected animals at the market have yet been identified, and not much is known about the environmental sampling other than significant contamination was confirmed at seafood market. It seems hard to square that fact with the high number of unconnected cases.
