Of course, the argument to be made from this, in some circles, will be
that evolution does not take millions of years to occur and this is in

general public and will sound like a scientific coverup.
One of the worst generalisations about evolution is that it mostly involves
random genetic mutations over long periods of time. I suspect that random
mutation plays only a very small part in the evolutionary process, and that
other processes (recombination, RNA interferance, learned behaviour, to name
a few) provide far more fodder for natural selection to act on, and on a
much smaller time scale.
Relying on random mutation is fine, as long as those mutations are actually
beneficial (which most aren't), and as long as your environment doesn't
change faster than *beneficial* random mutation can keep up with (which it
almost certainly will). Otherwise you'd better have some short-term backup
plans just in case.
