What did the groups of Aborigines who crossed a land bridge from Southeast Asia to Australia have in common?

All of the Aborigines that crossed from Southeast Asia to Australia had in common two things:

1. They were all originating from the so called ''Denisovan man'' found in Siberia.

2. They were all hunter-gatherers and remained like that till the European colonialism (and even nowadays the once that decided to live in the old way practice that life).
