International Committee on Taxonomy of Viruses accepted viruses as species in 1991. Viruses evolve by the same means as humans and other species, plus they use tricks such as stealing genetic code from other viruses.Have you ever hear of a virus?Until we see the actual first organism that started evolution then it is a theory.
You won't believe in God unless you see him, likewise I won't believe in evolution unless I see "Organism #1".
Yes.. And according to scientific theory and the "tree of life" as science draws it -- Viruses are NOT primordial relatives for the human clan. THey are one of the earliest branches AWAY from the lines of ascendency to apes and man.

We also see evolution in other microorganism, however it's much faster than more advanced species. Most microorganisms can reproduce rapidly and microbes such as bacteria can also freely exchange genes by conjugation, transformation and transduction between widely-divergent species. This horizontal gene transfer, coupled with a high mutation rate and many other means of genetic variation, allows microorganisms to swiftly evolve (via natural selection) to survive in new environments and respond to environmental stresses. This rapid evolution is important in medicine, as it has led to the recent development of 'super-bugs' — pathogenic bacteria that are resistant to modern antibiotics.
It's interesting that so many people are quick to reject the basic theory, however they certainly don't reject products of that theory.
