The paper I cited above that has an ancestor 40 years removed, is actually more closely related to SARS-CoV-2 than RaTG13. "We find RmYN02 shares a common ancestor with SARS-CoV-2 about 40 years ago and RaTG13—about 50 years ago" RmYN02 is only 93.3% identical to SARS-CoV-2 - a huge number of differences that could only occur from half a century of divergence in a wild population. There is also another virus more closely related to SARS-CoV-2 than RaTG13, but still too distant to have been involved with the pandemic, BANAL-52.
