Do we / did we even have the tech co be able to build this in a lab? I don't think we do. It MIGHT have been possible but Occam's Razor says it's more plausible it evolved naturally and just jumped species. FAR FAR FAR more plausible.
Do we / did we even have the tech co be able to build this in a lab? I don't think we do. A random virus, no. This one, we do. We can't build a virus from scratch. But we can combine pieces of different viruses to build a new one. The same thing also happens naturally when an animal is sick with 2 viruses at once. If both get into the same cell, you get various mixes created and sometimes a mixture will turn out to b…
I would discount the possibility that this was bioweapons research - the US was funding serial passage and gain-of-function research at this lab, of which the express purpose is to make viruses more infectious in different species, including humans.
At any rate, I don't think we can expect anything to be definitively proven. It is absolutely possible that this came out of the wild. But as the NY Magazine "Lab Leak" article illustrates, we should probably be open to the idea it came out of a lab. I also think we should reconsider whether or not serial-passage and gain-of-function research is something that can be ethically conducted. Anywhere.
