Population Demographics Tajima’s D statistic for all three viral genomic segments, as well as host cyt b , were −3.8, −4.5, −3.8, and −3.1 for the S, M, L segments and host cyt b , respectively, with all values being highly significant ( P < 0.01).
Shi and colleagues [ 58 ] provided a better understanding of the deeper phylogenetic and evolutionary history responsible for the current diversity in vertebrate viruses at the order and family level, revealing that an overall trend of codivergence is coupled with a complex history of host switching between distantly related taxa.
