Wuhan P4 Lab.
From the gene sequencing it looks like they spliced part of the SARS virus, a critical piece of the HIV and another one, which I have forgotten now.
Those pieces were not found in any individual animal.
One of the Chinese doctors said it was very likely out of the Wuhan P4 Lab. They were actively working on coronaviruses and had published papers on experiments that closely matched the SARS CoV-2 virus.
As one doctor noted, it was well known that they already had all of the pieces of the puzzle in place to do this, and the technology and expertise to do so was mature.
He attributed it to sloppy lab management.
