That was the contention of the argument that I was up against. That we cause less suffering because the deer could get mauled by a bear tomorrow. He was answering my argument that killing animals for food is unnecessary so it is undue suffering. He claimed he caused less suffering.

Unfortunatly, this is incorrect in terms of evolution. Species do not lose genes because of disuse. Genes disappear typically because they hinder an animals ability to survive and reproduce. Disuse will not cause a change in DNA and therefore will not change the human species.
Edit: Just to add...humans dont' "preserve" genes. DNA is what decides EVERYTHING about us. We have no control over what it looks like, how it operates, nor do we have the ability to change it (yet). If everyone stopped using their legs and travelled only in wheelchairs, the human species would not evolve to a legless creature.

Like I said don't know much about evolutionary biology. But it is true that DNA will only keep mutations that are beneficial, right, whether through selective breeding, etc..? It still doesn't apply to this but I am trying to clarify for my own knowledge.
