The China aspect is probably a red herring. Gain-of-function research was internationally funded, including by the US. The perils had been pointed out for years by virologists [1], some of whom managed to get an editorial in the New York Times against it [2]. If Covid turns out to be a lab escape (which is a big if ), the nation or lab it happened in is just the proximate cause. Deeper responsibility would lie with t…
> If Covid turns out to be a lab escape (which is a big if), It seems like we don't have evidence, but the natural evolutionary experiment that's occurred provides a staggering amount. We can see from the virus phylogeny that: 1. The virus entered the human population in October 2019. All known SARS2 sequences are related in a single clade that, under very soft assumptions about mutation rate, would coalesce in late…
There are plenty of viruses from animals known to infect humans, viruses that have never been in humans and are not evolved to infect them, this happens alarmingly regularly. Here's a couple you've probably never heard of: https://en.wikipedia.org/wiki/Australian_bat_lyssavirus , https://en.wikipedia.org/wiki/Hendra_virus
There is absolutely nothing amazing about covid being able to infect humans, it's exceptional because it can pass from human to human and because it's airborne(ish).
