A member asked:

Why don't caucasian people have an epicanthus (epicanthic eye fold)?

A doctor has provided 1 answer

Heredity: We develop characteristics that reflect our genetic ancestry. Most caucasians lack a lid fold but not all. A good question would be what is the survival advantage of such a fold which occurs so commonly in asians. Some think it helps with harsh environments, but what do you think?
