The Island Rule, or should I say the Mysterious Island Rule, it the well-documented phenomenon of small animals getting bigger and big animals getting smaller when they live in isolation on, you guessed it, islands. Hence the living komodo dragons and giant hissing cockroaches of today and the pgymy mammoths of Ice Age Catalina Island right of our coast here in Los Angeles. Some marine bioligists think they have an explanation. Which is fine, as long as it doesn't affect the status of our friend, the hobbit. Homo Floresiensis all the way!
