Figure 3 Evolutionary history of hepatitis E virus. The times to the most recent common ancestors (tMRCAs) for all four genotypes of HEV were calculated using BEAST to conduct a Bayesian analysis of HEV. The population dynamics for genotypes 1, 3 and 4 were analyzed using skyline plots. For details see text on HEV evolution. Source of data Purdy et al[50] 2010. HEV: Hepatitis E virus.
