The illustration next to Ray's post shows the transitional "concept" well...a creature turning into another creature, like a fish into a land animal.
Yes, Seeker. You found us out. If evolution were really happening we should expect to see a living fish just suddenly sprout a fully formed leg. And then they would be confused as to how to grow the other three legs. Since we don't see that happening, there are no transitional species. I think you've completely overthrown the scientific paradigm. Better sit by your phone. The Nobel committee should be calling you any minute.
Or maybe the only thing that cartoon demonstrates is that Richard Gunther has an even poorer understanding of evolution than Ray Comfort does. If such a thing is even possible.
