The issue isn't whether or not there are a few in-between species. If species evolved over millions of years, as you claim, there should be thousands upon thousands of fossils illustrating the complete line of evolution from one species to another. You're arguing that samples

prove

when to prove that, you have to produce all (or at least most) of the samples in-between. Since each step lasted hundreds of years and should have consisted of many animals, that shouldn't be too much to ask, no?
