Human adaptation remains an insufficiently studied part of the subject of climate change...Short-term responses to changes in land-based activities, which are identified as coping mechanisms, are one component of this adaptive capacity...According to the Inuvialuit, these observed changes are having an impact on hunting, fishing, and other subsistence activities as well as on guiding sport hunters and traveling on the land.
Adapting to Climate Change: Social-Ecological Resilience in a Canadian Western Arctic Community

I would say, as most physical anthropologists do, that race is a political rather than a biological concept. The skull is about the only place on the human form where you can make a connection with ethnicity. People have tried to connect the proportions of the femur, humerus, or ischia w/ race, but never with any success.
There's an Osteology lab manual by Bass that has all of the statistical measurements. I think it's in Bramblett & Steele also.
Take the nasal indentation of european skulls: what purpose does this serve? Well, I have a very short nose, while my wife, who is of middle eastern descent has a stronger nose. When I go out in the winter, my nose doesn't get nearly as cold as quick has hers. I know that seems trivial, but when I hunt, I notice it in my companions who have larger and more aesthetic noses. If you think on the temperature pressures in NW Europe, that kind of makes sense.
I collect old anthropology books. Its a hoot to spot some of the screamers that leap off the page today, but were sensical at the time (i.e. piltdown).
But wait. My college textbook (1985) has a chart of the visible spectrum that different colored irises respond to. It shows that blue eyes tend to contract more and faster when looking at a white field. This actually affects how quickly the eye is affected by "snow-blindness," conjunctivitis caused by staring at sunshine on snow.
It turns out that green eyes are prone to colorblindness, but see oh so slightly better in low light and grey light. Most green eyes are most common in NW europe.
As a hunter, I can tell you that the best hunting is right after a snowfall. The tracks make it obvious where animals are! There is no point in hunting while snow is falling, because it fills the tracks. But after the sun comes out, its the best time. I got snowblindness in highschool from hunting on a sunny day after a blizzard, so it is a real issue. And yes, I bagged one and nobody else did.
If you are following an animal than knows it's being tracked, they will often cut through a thicket, and then try to pop out the side of the brush once you've entered. Being able to see in low light, to spot the slightest movement is way more important than color vision at a time like that.
SO there ya go. Even eye color can have adaptive pressures on it.
