I read it and it does not make sense. It seems that the author doesn't understand that multiple traits can come from the same chromosome. If an important trait is selected (for or against) then the other traits "come along for the ride". Nothing mysterious about this.
Nothing mysterious, but his argument is that those traits are not selected at all. Floppy ears, curly tail, just there, no survival advantage at all, just along for the ride. So all the B.S. from pschological darwinists and so forth is exactly that . . .
