Extended Data Fig. 2: Phylogenetic trees based on the complete S and RdRp gene sequences of coronaviruses.
From: A pneumonia outbreak associated with a new coronavirus of probable bat origin
a, b, Phylogenetic trees on the basis of the gene sequences of S (a) and RdRp (b) are shown. 2019-nCoV and bat CoV RaTG13 are shown in bold and in red. The trees were constructed using the maximum likelihood method using the GTR + G substitution model with bootstrap values determined by 1,000 replicates. Bootstraps values of more than 50% are shown.
