I was questioning his "experience"

By the way, the first result on your link is theorizing, pointing out what is likely the presence of unknown genes which may be a unique variation of a "thrifty gene".
The second is paid article, from the summary, I can't tell what the conclusion is.
The third is what appears to be a global study, mentioning aborigines in passing.
The fourth is another paid article, but from the summary, it seems to be exploring alternatives to the "thrifty gene" hypothesis.
The fifth is about Hispanics in the US.

You see where this is going.
So tell me, for those who want to believe that diabetes among aborigines is caused primarily by genetic and not environmental factors, how are they confident that they aren't making the same mistake as pellagra researchers did in the early 1900s when they were convinced that germs, and not a poor diet, caused the disease?
