Photos taken around the world of some of the last forms of tribal life

Australasia and Antarctica

Oh right, but Antarctica and Australia either never had tribes or they assimilated themselves with the modern cultures

Well Australia has tribes, so I'm going to assume that Europe doesn't have any modern tribes, or that someone is just a bit daft

There is still tribes in Australasia but they stay away from modern civilization, some tribes in that region have never seen a white person

Perhaps the person meant that the Americas were one continent (since they are connected) as well as Eurasia? But that still leaves the question of Antarctica, since I do not believe it is inhabited besides by scientific researchers.

Or I guess you could just not include Antarctica, since it's not inhabited by a native tribe and count n. America and s. America as separate continents? (Or I guess for that matter, Europe and Asia?)

In Australia it's tribes of Aborigines
