An attempt at deep West Eurasian phylogeny

[Kale]

They don't have any 'Papuan' components, because Papuans, Melanesians, Australians, etc. are bottlenecked, and there was no major backflow to the mainland. Oceanians are basically a bottlenecked subset of the Hoabinhian/Andaman phylogenic region (plus the Denisovan of course).

What do you think about this paper, has this been confirmed by other studies?:

I'm not convinced. If there was a widespread mixture 4,230 years ago, I'd expect there to be a number of South-Asian haplogroups among Australian aborigines. To my knowledge there are none?
