Extinction of Species: Australian

The introduction of the Dingo, by the Australian blacks in their southward migration, is supposed to have caused the extinction of the Thylacinus (T. cynocephalus), or striped Australian wolf, on the main land of Australia, where it was once abundant ; it is now only to be found in the remote portions of the island of Tasmania. This destruction of one species by another is paralleled in our own country by the approaching extinction of the indigenous and now very rare black rat, which has been almost entirely displaced by the fierce grey rat from Norway.
