That's it? That's your obesrvable evidence? And you're gonna rest your entire theory on a mere 200 alleged exaples? Darwin claimed that there would be thousands of such examples! Your 200 finds are but 1/100th of the fossil record. Actually, the number of transition examples should be almost as many at the fully mutated variety.
Observable (it isn't today, nor ever has been), testable (we can't, don't and never will), repeatable (again...won't happen!)...those are the scientific rules for claiming something to be a scientific fact. You have demonstrated none of these requirements that the scientific field demands. Every example of a mutation observable in nature is a negative mutation.

Those are just the vertebrates. (Admittedly, vertebrates fossilize better than do a lot of the invertebrate life forms. Nevertheless, there's a growing fossil records for invertebrates including protozoans.)
What's so "iffy" about the two hundred examples I gave you that you can excuse dithering between "not ONE" and "just ONE?" Discredit an example for me:
A comparision of Eusthenopteron, a lobe-finned fish, with Acanothostega, an early amphibian:
A Comparision of their skulls.
What's an amphibian doing with a fish head?
