"Fiji is considered a Melanesian Island. Therefore, the strong relationship between Fiji and polynesia makes any such nonsense about a separation between Polynesia and Melanesia strictly nonsense."<quoted text>
The closest people culturally and physically to the Samoans and Pacific Islanders are the people of Fiji. This is amply documented in oral histories, physical archaeology and cultural traditions. Almost all histories and studies of the spread of Polynesian people starts with Fiji. Fiji is considered a Melanesian Island. Therefore, the strong relationship between Fiji and polynesia makes any such nonsense about a separation between Polynesia and Melanesia strictly nonsense. What they are really saying is that there is genetic difference between highland people from New Guinea and the Eastern Pacific, but highland New Guinea is not all of Melanesia.
However, this genetic study DOES NOT SAMPLE FIJIANS. Right there you see a big giant gap in the picture which makes the accuracy of the study suspect. Why? Because Fiji is like "Nubia", the "missing link" between Egypt and the rest of Africa, so by leaving Fiji out, they can pretend to present a separation between the Eastern Pacific and the rest of the Pacific that does not exist in reality.
Look at this map of the people studied:
Obviously, if ANY population is going to be closest to the people of Eastern Pacific it would be those of the Mid Pacific, like Fiji. So why did they not sample the people of Fiji?
We all know the answer to that one.
But beyond all of that, the sample sizes and the fact that they focused on New Guinea, which they themselves admit is HIGHLY GENETICALLY DIVERSE to begin with makes this whole study questionable to say the least.
Wrong. Fijians have long interacted with Polynesians, more so than their Melanesian neighbours. You act as if the scientists ignored this fact. Well why do you think they refer to Fiji as a 'Polynesian Outlier'?? But this doesn't mean that Melanesians and Polynesians are the same people. Fiji is more of a bridge than a 'missing link'.
