Insular dwarfism

This comic from Dinosaur Comics is a great comic summary of insular dwarfism:



The insular dwarfism wiki article has some great examples. And don't forget the opposite phenomenon of island gigantism, the removal of predators (and other constraints) on islands often can result in animals being able to grow larger after many generations. I learned something new, who knew that the dodo is just a giant form of a pigeon? Would that make Mr. Dodo the vice-mayor of Gigantic Towne? I think so.
