Evolution is genetic change, so random genetic change is a form of
evolution.

Of course, the _way_ a species changes over time is determined by the
sieving of variation produced by the mutation that occurs at every
reproductive act. During a time when a predator feeds on the
individuals that look least like leaves, the appearence of the average
individual is propelled toward a more leaf-like appearence, and so on,
hence the likes of leaf insects, etc. That's the neatest example of
evolution, useful because it can be observed within lifetimes.
