How the Kangaroos explain the theory of Pangea?
Kangaroos (and all Australian marsupials) are survivors of the breakup of Pangea. Australia broke away from Panagea before placental mammals evolved and established themselves, so primitive mammals (marsupials and monotremes) were able to persist only in that part of the world. The opposum (Didelphis) was lucky enough to have made it outside Australia.
