Phylogenetic network for HBV. The network is based on 511 HBV genomes (for references see Additional file 1: Table S7). The published ancient genomes [63,64,65,66] are highlighted in red and labeled in black, the newly sequenced genome is highlighted and labeled in blue. The capital letters represent the different clades, the label “Monkeys I” includes all strains from gibbons and orangutans, and “Monkeys II” the strains from gorillas and chimpanzees
