The original contention was that "1 in 10000" on FR accepts that evolution is even possible. The fact that Catholics have no problem with evolution, and certianly there are lots of Catholics on FR, makes that point laughable.
Argument from authority was not what I was doing. You missed another one.
My own definition, which has provoked a fit of red fonting, is that evolution (to most people) means that natural selection is the impetus that makes one species emerge from another, though conditions of geo isolation and lots and lots of geological time. This has proven too primitive a definition for some evos here, can you handle it?
