"Evolution means "change." Speciation is a change. Therefore speciation is evolution."
Oh, please. Therefore a rectangle is a square, by your deductive reasoning. Try harder.

No, it isn't. But just for giggles, *do* feel free to try to demonstrate your flawed assertion in a manner which is actually analogous to his point.
Try harder.
He's doing fine -- his definition is entirely correct. You might want to try again, however.
Evolution is change in a population's genepool across generations. Speciation is indeed a change in a population's genepool. Speciation is indeed evolution. Not all evolution results in speciation, of course, but then he didn't claim that it did.
If you actually want to try to dispute this, then you're quite simply incorrect. You might want to go learn something about biology before you attempt to discuss it, and *especially* before you attempt to "refute" it.
Also, is there any reason you dodged this request of his?
Define "macro" evolution, so I know we're on the same page.Besides the obvious, I mean.
Furethermore, you wrote: Creationists tend to believe that speciation is not attributable to evolution. Okay, I'll bite -- what exactly *do* they attribute it to? Be sure that you explain what exactly you mean by "speciation" in the context of your claim.
Speciation is a change. (C is a subset of B)
Therefore speciation is evolution.
(If A=B and C is a subset of B, C is then also a subset of A).
Better?
