D viruses can be genetically complex and have evolved many unique viral genes. The retroviruses show both quasispecies-based rapid evolution and host-linked slow coevolution (e.g. endogenous retroviruses). Thus virus evolution impacts all life and viral emergence continues to threaten human health.
