There likely will never be a documented slamdunk on the origin of Covid-19, but this study appears to be at least a “nothing but net” 3-pointer at the moment.
I logged this under “Health”, but I fully expect it to turn political in a heartbeat… kerthunk, kerthunk, kerthunk.
The “research” is loaded with supposition and very light on facts and data.
Many people who study actual data have basically said the “research” sheds zero new light.
