An example amongst tetrapods is, as best I know, a population of Rock wallabies
introduced to Hawaii earlier this century. They still look like Aussie rock
wallabies, but have quite different enzymes etc. Apparently, were it not for the
fact that they are known to be a feral population, they would otherwise be
unhesitatingly ascribed a new species. Apparently.

BTW, is anyone aware of any good fieldguide to all of Australia's mammal
