I haven't been to school for 15 years and even back then I completely sucked at biology. But I think I still remember a plausible explanation: Bacteria reproduce asexually, their "children" are genetic clones. Thus they are completely missing one of the three pillars of evolution (mutation, selection and recombination), namely recombination. As far as I remember, evolution was very slow until the "invention" of genders/sexual reproduction anyway. |
Some bacteria do engage in recombination, via a structure known as a pilus.
At any rate, do to their immense propagation rates and short regeneration time, they produce many, many mutations and thus should 'evolve' relatively quickly, as seen in experiments with resistance to antibiotics in bacteria.
