Charlie the Coelocanth says, "Deep, cold water is deep, cold water."
Nice picture, however repeating the statement which I just refuted does nothing for your side. Here's the refutation again in case you wish to argue against it:
what happened to mutations? Certainly these species were not perfect. There could have been numberous improvements to them that would have been helpful - a smarter brain, better fins, changes to make it reproduce more or better. Clearly there are many possible changes which mutations could have achieved (especially in such a long, long time) to make it more fit? Heck, you know, as a matter of fact, that is how punk-eek works, a species improves itself in a secluded habitat and through super-evo transformation takes over the world! Clearly these species had enough time to do so. Or are you perhaps trying to tell us poor fools uninitiated in the church of evolution that the demi-god Darwin told this species "you shall not mutate any more, you are fit enough already and you have not been chosen to be the ones to take over the world"?
