"I failed to clarify that it is not believed that existing species 'evolved from one another', but from common ancestors."

Then I fail to see how evolution explains anything other than variation within a species.

I think I see why you have a hard time accepting evolution, then. Tell me, if you witnessed a dog giving birth to a cat, or a monkey spinning around and morphing into a human, would that prove or disprove evolution to you?

If you can show me evidence of that really happening, I would have to completely rethink evolution. ;)
