True or false the theory why Scandinavians and Eskimos have wide cheekbones

[lurking truecel]

The theory is about mouth breathing ofc, we all know from scientific studies that the face become long and narrow from mouth breathing. It also creates crossbites and open bites that will fuck up the face even more.

I mean this is probably one of the most famous studies on it but they also done it on other animals and ofc can even be shown on humans. Mew showed it on one observation the twin experiment.

But yes the theory I heard about is colder climate and better humidity air makes it easier for humans to nose breath and that's partly a reason why scandis and Eskimos looks better esp, the cheekbones. True or false ?

Tis true, dwelling in a colder climate over centuries makes it so that you get adapted to it and it's environment. Therefore making your face wider by the need to not breathe through your mouth and other bad habits.
