Homology plot analysis of "dataset_6" also revealed that BetaCoV/bat/Yunnan/ RaTG13/2013 was more similar to the SARS-CoV-2 virus than the coronavirus obtained from the two pangolin samples (SRR10168377 and SRR10168378), consistent with phylogenetic analysis ( Figure S5 ). 46, 47 Bayesian analyses with the tip-dating method using a strict clock as well as constant size coalescent tree prior indicated that SARS-CoV-2 is evolving at a rate of 1.24 × 10 −3 substitutions per site per year (Table 1 ), in accordance with our prior research 46, 47 and similar to that found for other human F I G U R E 4 Estimated maximum-clade-credibility tree of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using tip-dating method.	./cache/cord-253905-zknmfgsh.txt	./txt/cord-253905-zknmfgsh.txt
