The Origins of Australia

A 1960s book described the aborigines as quote. The most backward race on Earth before going on at grade length about the mining and stock raising industries. We do know Aboriginal history, but just the dingo arrival thing got kind of completed in with other things. What we were trying to say was that the dingos arrived with some humans who also arrived that long ago. It's hard to guarantee that we'll hit them all. Just the volume to our production ratio is not possible.
