don't southeast Asians still have them?

The epicanthic fold is often associated with greater levels of fat deposition around the eyeball. The adipose tissue is thought to provide greater insulation for the eye and sinuses from the effects of cold, especially from freezing winds, and to represent an adaptation to cold climates. It has also been postulated that the fold itself may provide a level of protection from snow blindness. Though its appearance in peoples of Southeast Asia can be linked to possible descent from cold-adapted ancestors, this does not explain its occurrence in various African peoples. The epicanthic fold found in many African people has been tentatively linked to protection for the eye from the high levels of ultraviolet light found in desert and semi-desert areas.[21]

The exact evolutionary function and origin of epicanthic folds remains unknown. Scientific explanations include either random variation and selection (presumably sexual selection), or possible adaption to desert environment and/or high levels of ultraviolet light found in high-altitude environments, such as the Himalayas.

Frank Poirier, a physical anthropologist at Ohio State University, said that the epicanthic fold among Asian people is often explained as part of an adaptation to severe cold or tropical environments; however, he suggests that neither of these explanations are sufficient to explain its presence in East and Southeast Asia, and notes that the fold can also be observed in Irish and African people. He attributes the epicanthic fold to pleiotropic genes that control more than one characteristic or function. He also did not offer an explanation for the origin of epicanthic folds.[22]

The trait developed thousands of years ago back when asians were still in siberia

You ever see the video of that Chinese welder who doesn't use a welders mask he can just tank it. So it may not be pseud basedence bullshit

>>509277081 (OP)
Probably a weather related adaptation
Or maybe some ancient Siberian was randomly born with them, and every dude around her was like “holy fuck that is hot”

What the fuck is Epicanthic folds?

*snow. long eyelashes protect against sand.

THEY MAKE ME HORNY.

But in all seriousness they're cute and I can't fucking explain why, other than the fact I'm a mutt with Asian blood in him.

Not much.
Thats why we lost them.

The truth is that the people in asia didn't acquire epicanthal folds. Everybody else lost theirs. Thats why people with downs syndrome have them. The extra chromosome triggers the ancestral folds.
