Notice that the divergences 14 between human SARS-CoV-2 and the bat viral sequences, RaTG13 and RmYN02, in most 15 regions of the genome, are quite low compared to the other comparisons. While the overall divergence in the S gene encoding the spike protein could suggest the 10 presence of recombination in the region, previous study ) reported that the tree 11 based on synonymous substitutions supported RaTG13 as the sister taxon to the human SARS-12	./cache/cord-260508-z11exbyu.txt	./txt/cord-260508-z11exbyu.txt
