Violin Plot from Scientific Research

Time of the closest-inferred bat virus ancestor of SARS-CoV-2 across the 44 NRRs of the SARS-CoV-2-like viruses. The 20 years before the emergence of SARS-CoV-2 is highlighted in gray in the upper panel and shown in the lower panel. The dashed line in each panel is the date of the earliest sampled human case of each SARS-CoV (November 16, 2002 for SARS-CoV-1; December 24, 2019 for SARS-CoV-2). The violin plots correspond to the 95% highest posterior density (HPD) intervals and the dot within each violin plot indicates the median. The location of the Spike (S) gene is indicated in the top panels of (B) and (C). See alsoFigures S1S4.
