So by that logic shouldn't cold climate people's have higher desaturase activity?Yes, the mutations concern desaturating plant PUFA further into things like arachidonic acid and omega 3s.

But humans can't saturate points past the 9th carbon, can't make AA or LA etc. without an n-6 as a precursor. So what's the point of being able to desaturate without precursor material to work with?No. If you have a lot of animal PUFA or even plant PUFA in the environment, the person doesn't need to synthesize AAs as much, and probably benefits from synthesizing it less.
If you have very little PUFA, the person needs higher desaturating activity.
But as the data shows, reality doesn't follow the logic so well.

mm skeletonsHonestly, she really doesn't look that good from a Japanese perspective. If you are looking at her from an American average land whale perspective, then yes she is skinnier. But she looks chubby to me in comparison to the average Japanese girl look. Her face is way too plump.

The mutation allows further desaturation of parent n-6 and n-3.
cold environments contain more plant PUFA, more animal PUFA, and more fat in general.
So cold people will tend to have more linoleic acid and arachidonic, DHA, etc. in their diets.
Thus, they will need to desaturate less to compensate for the high PUFA diet.
Probably to some extent, but "cold adapted" doesn't really have anything to do with most modern people.are there any benefits to PUFA consumption for people who live in cold environments?
