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).

All the groups of 'Aborigines' who crossed a 'land bridge' from Southeast Asia to Australia honored the 'natural world' around them.

Explanation:

When the sea levels were around 130-140 meters lower than what they are today, a huge piece of land named the Kumari Kandam joined Southeast Asia to the present-day continent of Australia. The aborigines used this land as a bridge to cross over to Australia. All these groups of aborigines that migrated to Australia had one thing in common, and it was that the all feared, worshiped, and honored nature because they believed that nature is the 'driving force of all'.
