The transfer of plasmids is a very common method of spreading new traits in bacteria.

Genetic variation can be introduced by mutations or by transformation (picking up and incorporating random pieces of DNA from the environment). DNA can be spread from one bacterium to another by conjugation (bacterial sex) or by transducton (rare transfer from one cell to another by a virus).
