I have been meaning to get into this idea. Considering that Nordic Europeans tend to be quite tall and Mediterraneans on the shorter end and Northern Chinese(and I guess Asians) tend to be taller than southern, , is height variance between groups of people influenced evolutionary by the physical environment some how? Mainly the climate? Nutrition/diet taken into account of course. Can it be mostly cultural diet from childhood? For example, most East Asians are lactose intolerant and milk protein is a easy source of protein for height. Asians get their protein from other sources besides soy though no? Also, I think it is safe to realize that not all Black Africans are tall though how much of it is due to nutritional deficiency is hard to say. A decent percentage of the population is also lactose and tolerant though. Can there be some link between climate and height or lactose and tolerance and height or both?

There may be some dependence, but remember
there are many other confounding variables,
mainly those resulting from culture.
I guess what I am trying to say is, can the genetic variances in height be a purely due to adaptation to a physical environment/ climate or is it related to diet(due to cultural and genetic differences in what people eat and can eat/digest)?
Do you think the genetic variances we see( some 60-50%) could be an adaptation that people have for example, to the climate? I guess I'm stuck on on the fact people from the northern regions tend to be taller.
But this map of lactose in tolerance kind of lines up with the differences in height variance we see in the world, too. Consider that an easy source of protein for growth in kids who have been weened is cow/other mammalian milk.
Could one or both of these be the missing link in heritable height differences?

Nutrition and environment probably are more important than even genetics barring people with growth disorders.
The only reason Asians are still shorter is because we are getting taller at the same rate.
Running down things to eat because you are too stupid to farm or make long distance weapons can be a huge factor in passing on your lanky genes in some places.
Hey welcome to the thread /pol/.
Prosperity is a pretty good measure for predicting height within groups.
Is this supposed to be English? I don't understand what you're saying but, the only nutrients most important to height growth is protein. Less protein is found in farmed crops than meat and milk. Milk is the easiest source of protein even for the poor. You just need a couple of female cows/goats.
It doesn't answer my question though.
>Less protein is found in farmed crops than meat
Asian countries have a more vegetarian diet which could explain their differences from western countries.
