Main Question or Discussion Point
The original article (which I have not read) is at:Analysis of the virus's genome was ambiguous. Some analyses placed its origin within the local bat population. Others highlighted similarities to pangolins, which might have been brought to the area by the wildlife trade. Less evidence-based ideas included an escape from a research lab or a misplaced bioweapon. Now, a US-based research team has done a detailed analysis of a large collection of viral genomes, and it finds that evolution pieced together the virus from multiple parts—most from bats, but with a key contribution from pangolins.
