... So there is a range of methods for defining a species, and people use whatever method works best for their group. Bacteria, which exchange plasmids of DNA at will, don’t have genetic isolation, so the idea of species is merged with the term “strain” (see Mario’s lecture on this). Virologists aren’t ...
