The Darwinian Impossibility of King Kong

I'm not too much of a fan of King Kong, not the old, old version, or the eighties remake starring Jessica Lange - who a buddy's uncle in Minnesota dated once - and I don't think I will be one of the Peter Jackson version that's set to hit the theaters soon. Don't get me wrong. It looks fantastic and clearly Jackson's vision is realized in this version. From what I understand Jackson has been a Kong-o-phile since he was a little kid, so this thing is his life's dream come true. Don't tell him, but I never got into it much. I didn't care for any of the characters, like the girl or the scientists or anybody else in the story, and especially not King Kong. Sorry. Maybe Jackson's version will be different, but I don't think I'll give it a shot. The reason why King Kong would be an impossible creature is because of something called 'the island rule' which is something biologists have known ever since Darwin. Maybe even a bit before. On islands the resources for the creatures living on it are limited, so two thing happen. First: The big creatures become small, because food is limited, and Second: The small creatures become bigger because they have to compete for that limited food. On some islands scientists have found the remains of both giant mice and miniature elephants. King Kong is discovered on Skull Island which is over-run not only with King Kong, but with other giant prehistoric creatures like dinosaurs and such. Well, It couldn't happen. What on Earth are all of these giant animals eating? The food suppy wouldn't support them. They would literally eat themselves out of house and home within a generation. If I remember the story correctly, superstitious villagers on skull island set out virgins on stakes for Kong to eat, so that would help things out there. But how many of those can there really be? Not enough to feed a monstrous gorilla, that's for sure. You know, I don't think you could find enough virgins in the whole continental US for that.
