@Gwazi: His belief that animals service us has nothing to do with evolution. One can hold that belief regardless of where they believe they came from, mate.

In a sense they do serve us anyway. As pets, companions, and food. It's simply logical to treat them better because then more survive for us to eat and less diseases have the chance to evolve and jump species to us.Beyond that, it matters not how one feels: We eat them. :lol
