I agree that memetic evolution has Lamarkian components for the reasons you
outline. Too much variation, is not enough, IMHO, to dismiss Darwin. Random
variation due to solar radiation, background radiation, poor genetic copying
etc can all produce poor copies. Faithful copying would lead to stagnation
in any form of replication in the face of a changing environment. As in
life, so in memetics. Each changed DNA/meme is tested in an environment and
those that are fit reproduce. Hence DNA changes and memes change.
