Thank you for those links. I appreciate the new inputs. ("Sampling bias and incorrect rooting make phylogenetic network tracing of SARS-COV-2 infections unreliable" and "Median-joining network analysis of SARS-CoV-2 genomes is neither phylogenetic nor evolutionary")
Do you think that these conflict with the statement Forster made that "I would be a bit careful about pinpointing a place (of origin), because we don't have many samples from the early phase," he says. "But it seems to me we shouldn't restrict ourselves to Wuhan when looking for the origin." [0]. They did have a variety of samples, enough to throw doubt on where the origin was, right?
I brought this up just to point out that it is not a foregone conclusion that Wuhan was the location of the first covid-19 cases in humans. Do you think that is an incorrect statement?
