Ken -

Thanks for the thoughts and I am still thinking about them. However, are you
sure parasites don't "create their hosts?" What about the bacteria Wolbachia
which seem to be able to increase the percentage of females in species they
infect? In some Hymenoptera Wolbachia can change male eggs in to females by
preventing first cleavage and producing diploid eggs. Nor am I convinced that DNA
create their host anymore than I am convinced that IQ is entirely genetically
determined. I might also remind you that proteins created by DNA are subject to
post transciptional modification resulting from the cellular environment.

I tend to see evolution as a hierarchal and forces working at gene level are
not necessearily those work at the species level.
