|The Tao (Yami) people are central to this research
There’s a new open access paper on the genetics of some isolated Malayo-Polynesian speaking peoples of the islands between Philippines and Taiwan:
It is probably important for what it adds to the knowledge not just of these isolated peoples but specially of their neighbors and relatives through all SE Asia.
There is a lot of information and emphasis on Y-DNA and much less so on mtDNA, probably indicating some bias on the side of the researchers.
Critically molecular clock hunches are shown to be wrong again:
Finally, artifacts dating 4,000 YBP, found on Orchid Island and indicating association with the Out of Taiwan hypothesis might be related to a pioneering stage of settlement, as most dating estimates inferred from DNA variation in our data set ranged between 100-3,000 YBP.
As if DNA age guesstimates are any better than archaeological hard evidence. Please, geneticists of the World, step down of the molecular clock silly pedestal as it’s as feeble as the belief in creationism. Reaching conclusions based only or mostly on molecular clock conjectures only makes fools of yourselves.
Something as simple as undervaluing the Pan-Homo divergence by 25% (a systematic widespread error) will cause the errors you are displaying here, as the 4000 years BP are in fact a calibration point, not something you can even discuss based only on erudite (but typically wrong, unscientific and never demonstrated) algorithms.
The authors emphasize some Y-DNA connections between the Batanes
or Philippines and the Tao
(Yami) people of Orchid island but they choose to ignore the many other instances in which the Tao are more directly connected to Indonesians, Thai or the Taiwan Plain Tribe.
In any case a data mine for all interested: table S3
in particular has NJ trees for a number of major Austronesian/SE Asian Y-DNA haplogroups.
