Of course. There is a vast difference between redwood trees and elephants,
but both are living things (and replicators, of course).

Different levels are involved though there are all kinds of odd crossed
over effects. Memes (Shakers, Heaven's Gate) can have had the effect of
particularly lethal genes. Biotech firms write copyright notices in DNA,
so they could write anything. And then there are memes that disguise
themselves as warning about computer viruses.
There are interactions between the levels too. Memes that are too hard on
the genes of their hosts like the above examples tend to die out. Computer
viruses are held in check by memes that are spread about them. (And in
turn *this* level is hijacked by false warning as I mentioned.) "Fleas
with fleas to bite them ad infinitum."

True, but rapid progress is being made in this direction. The works of
William Calvin are particularly instructive.
