First, you have to agree to use some other term than speciation. If you're using that word to set up creationists to whip the London mosquito on them, then you're simply being intellectually dishonest and you can disregard the rest of my post. But I'm assuming that's not what you're doing, and that you are using the word "speciation" to mean something on the order of a dinosaur evolving into a bird.
In fact, it would probably be best to avoid all of the standard terms like phylogeny, etc., because they are loaded with imagination rather than facts. For example, phylogenic trees (at least with respect to evolution) are what we "imagine" to be the relationships between creatures and their ancestors -- they aren't proof that there are such relationships.
So what would I accept as evidence? You must offer irrefutable evidence in the fossil record, or demonstrate observable evolution (as in dinosaur-to-bird evolution) occurring through natural causes. To elaborate:
1. You can provide the fossil evidence of the gradual evolution of the magnitude of a dinosaur turning into a bird. The only way to do this is to present millions of transitional fossils that show how the features evolved gradually over time. What you can NOT do is show a couple dozen fossils that look like they might have been steps within a transition, because that is not an observation of evolution, it's observation of similar looking things that you can connect only with your imagination. If you can connect them with millions of transitionals, then it's no longer imagination, it's hard evidence.
2. You most prove that you have observed evolution of this type "in the lab." I put "in the lab" in quotes because you can't do it in a test tube with intelligent intervention. Human intervention invalidates the premise of natural causes. The only way to provide hard evidence for evolution by natural causes is to block off a wildlife preserve and observe all the life within it for a few million years until you've recorded the equivalent of the process of a dinosaur evolving into a bird.
Any takers?
