Now, hold the phone, Paul. If an animal develops a new trait, especially
one that basically defines his whole lineage from thereafter, I'd accept
that as pretty obvious that the trait was more, not less efficient.
Positions contrary to the obvious rightfully should be supported by the
contrarian. Otherwise we should all have to spend out time reproving the
theory of evolution, gravity, epicyles...:>.
