English: "a Maximum likelihood phylogeny of the subgenus Sarbecovirus (genus Betacoronavirus; n = 39) estimated from complete genome sequences using IQ-TREE and 1000 replicates. The coronaviruses of the SARS-CoV-2 lineage are color coded by country of sampling as on the map. In orange, Cambodia, light orange, Thailand and blue, China. Taxa names include the isolate name, country and province of sampling, and host. The scientific names of the hosts are abbreviated as follows: Bats: R. affinis, Rhinolophus affinis; R. sinicus, Rhinolophus sinicus; R. ferrumequinum, Rhinolophus ferrumequinum; R. malayanus, Rhinolophus malayanus; R. acuminatus, Rhinolophus acuminatus; C. plicata, Chaerephon plicata; R. pusillus, Rhinolophus pusillus; R. macrotis, Rhinolophus macrotis; R. monoceros, Rhinolophus monoceros; R. cornutus, Rhinolophus cornutus; Pangolin: M_javanica, Manis javanica and human: H. sapiens, Homo sapiens. A maximum clade credibility tree is available in Supplementary Fig. 3. b map of parts of China and Southeast Asia. Regions where viruses of the SARS-CoV-2 lineage were sampled are colored as in the tree. A black dot indicates a sampling site when known, and the red dot shows the location of Wuhan, where the first cases of SARS-CoV-2 infection were reported."
