Rabbits are not native to Australia, having been brought there from England by sailors in the ${18^{th}}$ century. Yet rabbits have thrived and have in fact overpopulated Australia. In addition, rabbits and certain native Australian wallabies, although not closely related, resemble each other as to body structure and habits. Which idea about evolution is supported by these facts?


Though rabbits and wallabies are not closely related and their geographic origins are distant, their similarities and the rabbits ability to survive in similar habitat supports the idea that widely divergent species can evolve in similar ways when reacting to similar biogeographical environments.
