The success of some viruses lies in their ability to evolve rapidly within the host. such a virus evades the host’s defenses by mutating and producing many altered progeny viruses before the body can mount an attack. thus, the viruses present late in infection differ from those that initially infected the body. discuss this as an example of evolution in microcosm. which viral lineages tend to predominate?
