Good anecdote. I also had a "weird cold" in February with symptoms that are unusual for me but typical of COVID-19, and have been waiting to get the antibody test. I kind of expect it to turn out the same way. (Otherwise, I would really like to figure out what the "weird cold" that everyone had in February was. Because it sure was weird, and everyone I know had it.)

I keep reading people asserting this, and I assume it's because we believe that a virus that becomes less lethal would have an evolutionary advantage. But, wouldn't lengthening the incubation period also be a successful evolutionary strategy regardless of lethality? It seems to me that there are many possible strategies that a mutating virus might gain an advantage and we shouldn't just assume that the only one that…

'Tend to' doesn't mean some conscious, directed effort. On large enough scale, this is generally the more probable direction, and that's about it. Its truly random by nature. It can very well go the other way as with 1918 'spanish' flu. Or it can change in ways that won't affect overall mortality much.

I think the main evidence against it being here siginifgantly earlier is that we see how it spread when it was definitely here, so why wouldn't we have seen hot spots like Atlanta and New York earlier then?

Your FB feed results don't seem impossible. First CV-19 death in CA was Feb 6 [1]. That's presumably at least a couple of weeks after infection. [1] https://www.nytimes.com/2020/04/22/us/coronavirus-first-unit...

The question isn't whether they're possible, it's whether the antibody tests are reliable that far from the actual incidence of C19.
