Current thinking regarding ancient movement from Southern China into northern Taiwan

[loxias]

Very interesting.
You should try it again by adding British averages to the source list and getting rid of Sintashta and Yemenite samples. I had added those mainly because Northern China and Southeast Asia respectively. Let’s see if getting rid of them impacts that high Fujian score or not.

Here we go. As I've mentioned elsewhere, I haven't done as much Ancient modelling as Modern, so let me know there's a better British sample to use. I wasn't expecting Fujian to disappear completely.

Honestly I would have used contemporary British Isles samples (Wales, England, Cornwall, Irish...) considering those populations already existed when West Eurasian admixture in Maori took place.
That said, England_MBA already did quite a number on that earlier Fujian_N result, the distance has dropped. Things look a bit more expected.

Fair point. Just for the sake of comparison. Fujian makes a return (except when using Irish only).

Very interesting, the Fujian crops back up every now and then. I wonder what it is due. Which island did Maoris come from before getting to Aotearoa?

More like islands, as they migrated through a number of islands to get to New Zealand. Here's a map of the general route:

[loxias]

Not surprised to see the "Bajo" (Sama-Bajau) sample come out on top as they have sizeable Papuan-like admixture, although I don't think the Papuan admixture in Maori was picked up the Sulu archipelago or anywhere West of the Wallace line for that matter.

Liangdao is the closest site (geographically) to Taiwan out of all the Fujian samples. Perhaps it is connected to Austronesians after all? I think I will try Vahaduo runs soon, I want to see what happens when I exclude Qihe from the Fujian group as well, as it is a bit of an outlier.

I'm not surprised by the Bajo and those results, as when I model myself, it and Batak are normally the best fitting Indonesian populations.

I just came across this recent article which reminded me of this discussion, so I thought I'd share it:
