The Land Down Under
Ed Vinson asks just how far it is from Mt. Ararat to Sydney, and which of Noah's sons got stuck with herding all those numbats, wombats, platypi, and wallabies down there without mixing any rats in. G'day, Mate!
They live only in Australia. Their diet is so restricted--to a few subspecies of eucalyptus--that they're threatened now by destruction of the only kinds of trees they will eat. It's also hard to imagine them migrating. Over many generations they might slowly spread through an area--but travelers, they ain't.And when they did migrate over 9,000 miles, in a tiny herd from Ararat to New South Wales, eating a convenient trail of long-disappeared eucalyptus (which took how many years after the Flood to grow?), they left no trail of koala fossils behind.
