epicanthic eyefold ideal?

[Deleted member 1973]

The epicanthic eyefold developed to protect the eyes in cold weather, as in the high altitude and northern latitudes of Mongolia. But also in the cold, high altitude regions of Scandinavia. In Scandinavia in fact, it's called the Scandinavian Eyefold. And also developed in the high mountain ranges of South America. It probably evolved independently, but for the same reason.
