1. Were these remains of the different species found in the same geographic location?
2. How complete were the skeletons and/or fossils on which the hypothesis is based?
3. Exactly why is it presumed that figure b represents a transition from a to c? I can see how one could make the presumption, but we are still stuck with the problem of transitioning from fins to legs, from gills to lungs.

What exactly do you imagine Darwin_is_passe is asking to see in the fossil record when he asks "Where are the transitionals?" If what we do see in the fossil record is different from this, what is a fossil-record transitional and how would you know?

Your ability to get stuck may not be science in the purest sense of the word.
