### Evolution occurs whenever selection forces act on populations of
non-identical individuals, capable of accumulating changes to their
characteristics, and transmitting such changes to the next generation.
The subjective experiences of these individuals are not relevant to
the issue, except insofar as they are related to differential fitness.
We are still subject to this process, although the severity of
selection appears to be for the time lessened. Of course, substitution
of economic or technological success for physical characteristics such
as hair, as the variable acted on by evolution, does not stop
evolution, merely redirects it. Natural selection still continues to
occur, since there is clearly differential fitness as measured by the
number of surviving offspring among humans.
Evolution would be abrogated only if there was no selection, and no
differential fitness, or if variability was removed from the
population and prevented from appearing again. A singleton AI could
perhaps institute such a regime, by preventing death and
simultaneously by limiting or regulating procreation.
It is interesting to note that we may be undergoing a transition from
a Darwinian evolution to an almost exclusively Lamarckian mode.
Acquired and desired characteristics will become heritable and will
provide the vast majority of the variability between individuals that
is necessary for selection to occur.
