Genetic variance of influenza type A avian virus and its evolutionary implications

“…The [bird flu] virus that causes disease is made up of eight RNA segments which code for its protein components. The bird flu spreads so rapidly because it is often present in migrating birds that show no symptoms. These birds pass the virus to domestic birds that do not have a natural immunity, which leads to outbreaks in the domestic populations. The ability of the virus to constantly change its protein coat makes vaccination virtually useless. The genetic variation within the virus is observable, but it does not support evolution in the molecules- to-man sense. The genes are simply slight variations that code for a protein that performs the same function. Viruses can change, but they cannot evolve to become anything other than viruses.” Evolution Exposed, Second Ed., Genetic variance of influenza type A avian virus and its evolutionary implications, Kitner.
