If it was lab created independent scientists would be able to figure it out and there would be evidence that it was. But it looks like there is not:

Now maybe the virus mutated from those initial 174 cases but that's unlikely.

China does have a narrative that covid19 reinfections are coming from imported frozen foods though so I'm not sure why they are pushing that angle. It's probably an economic one and to save face. But maybe it's real.. if it is we are screwed.




I don't feel convinced by the argument. Maybe someone can help me understand better.

- Virus infects human ACE2 suboptimally, therefore it's not lab grown. Why? Because a virus engineer is always going for maximizing spread rate? Seems plausible that less-than-ideal infection rates of humans could be a feature rather than a bug.

- A polybasic clevage site was not seen in SARS-CoV... but it's function is not known. Okay?

- The virus backbone was "0day" and not previously known to researchers. Seems like a feature that a covert bio warfare lab would desire.

The rest of the speculation seems to ride on the assumption that the virus originated in China (despite evidence showing otherwise[1][2]), and their discovery seems biased toward any data to support that conclusion.

You are correct. There is both gain of function and loss of function happening in these types of experiments.

Firstly that was in March. Secondly it discounts the serial passage research which leaves little genetic evidence. All the potential sources are unlikely, so why discount a lab accident?
