do you realise that even modern scientists state that one of the theories of aus aborigines are that they are a hybrid of chinese homoerectus and indonesian homoerectus? of course it's never stated in the media or uni classrooms but quietly on science pages etc. they confirm it's a valid theory.. meaning of course that if modern science is even admitting that then it's very very likely the right answer, but they cannot confirm or state that in the modern age so they just leave it floating as a theory
