We have living proof that speciation is often very incremental in ring species. There is a species of salamander that ranges around the Central Valley of CA (eastern & southern side IIRC) where nearby ones can always breed with other nearby ones, but if you take the most northerly ones and the most southerly ones, they can't, i.e. those are different species, despite the fact that nearby ones are the "same species". How can that be? Thats a living example of spatial speciation. All of us are descendents of temporal speciation. While we have all descended from an unbroken line of ancestors, and each of our ancestors could clearly breed with those living at the same time, NONE of us now could breed with ANY of them (assuming we had time machines) if the time separating us is large enough. Its no different than ring species today. You don't need a species to split to have speciation, a single line also becomes a different species over time without any split at all. Thats what is so LOL funny about creationists. Many of them accept what they call "microevolution" but they deny what they call "macroevlution". They are the same thing. If you accept one and are intellectually honest, the other follows automatically. They really do think that the only "proof" of evolution would be a cat giving birth to a dog or something equally idiotic.
