Line Plot from Scientific Research

Timescaled maximum clade credibility (MCC) phylogenies of individual NRRs (NRR14 for SARS-CoV-1-like viruses and NRR37 for SARS-CoV-2-like viruses) obtained after correction for substitution saturation, shown on a log-transformed timescale. Horizontal segments displayed at each internal node indicate the 95% HPD interval of the estimated node age, with a light gray vertical bar indicating the median node age. The closest-inferred ancestors of SARS-CoV-1 and SARS-CoV-2 are indicated by red arrows.
