Human dna would be interesting particularly if it proves that current day aborigines were not first occupants.

@FrayedBear It seems that people are looking to displace aboriginals..and first nations and natives to say.. O you weren't the first here. Even though native history shows occupation for many thousands of year at least.

@AmmaRE007 Try applying that philosophy to Israel. Probably the Mesopotamians and Assyrians (Syrians, Iraquis and Turks) have the best claim. Their occupancy predates early Jews. Even the old testament verifies that the wandering Jews usurped the 'promised land" from the peoples who were there.
How's that for throwing the cat among the pigeons?

@AmmaRE007 Many who have settled and successfully lived in an area have been suborned by violent malicious invaders. Yes it is nasty, ugly & inhumane but until human DNA is manipulated to prevent such behaviour it will not change. Incidentally it is interesting that Australian Aboriginals traditionally do not believe in possessions and certainly have no concept of land ownership - they consider themselves custodians.
