What sciencemag quotes, > It suggests they had a “most recent common ancestor”—meaning a common source—as early as 1 October. what the quoted link says, > The first case symptoms was recently reported to be December 1, 2019 5, although WHO has previously reported this as December 8, 2019 1. The estimate from BEAST is in agreement with these dates, giving a median date of December 2, 2019. This date is also consistent with prior phylogenetic analyses using fixed rates of the evolutionary rate of 2019-nCoV.
