Another article about the research done  on the DNA showing that more that 85% of the Taiwanese have aboriginal/austronesian ancestry :

Please, note that I've been told that there is a big translation mistake in the Taipei Times article.

In the article, when 'Vietnamese' is mentioned the first time, it should be understood as 'Yueh people'.

Here is the corrected version : 'Lin said Hoklo and Hakka DNA was diverse. She said the tests showed that more than 90 percent of Hoklo and Hakka have at least some Yueh ancestry, specifically from China's southeast coast."

Frank, I thank you for telling me about this.
