However, as I posted previously, the types of coronaviruses that share almost all of the genetic make-up of SARS Cov2 are found over wide areas of China, South-East Asia and even in Japan (probably elsewhere as well). We have no reason for thinking that the one that orginated in Yunnan is the one that has emerged as SARS Cov2. There could likely be several areas from which it broke out.
From what I have read, when looking at the whole genome, the closest related virus to SARS-CoV-2 continues to be RaTG13, collected from a cave in Yunnan.
I have not seen any conflicting research that proposes a closer 'whole genome' match. There could be, or might be in the future.

If you are aware of new data, let me know.
