If it were to me, I would create new scientific term to describe asiatic people.
"Mongoloid" was racist term used by whites to degrade the appearance of asian people.It's original
definition refers people with down symdrome or born with retarted faces.Even inbreds who were born from incests were branded as mongoloids, it even mean't people born from an degenerated of caucasoids, back than these people were considered freak of nature.
Here is the original defination of mongoloid.
Mongoloid is now the scientific term to describe the people back than in 17th-19th century it had extremely offensive meaning.East asians were exaggeratedly depicted and were called slanty eye monkeys and were ridiculed by whites. Whites would stretched their eyes to offense.This term was also used to humiliate the finns by calling them mongoloid.Even today finns will get very pissed off if you call them mongoloid. In fact this made the finns feel they were inferior because of there features.
Round eyes phenotypes exists in every race.Not all asians are born with slanty eyes.Different phenotypes can evolved due to the different enviroment you live in not because of any bull$hit admixture.Many finnish people and north europeans have slanty eyes too, many indegious finnish tribes have slanty eyes too but not because of admixture but due to the cold weather that made their eyes shrink.Southeast asians have dark skin because there closer to equator, just like south americans who's phenotypes evolved too.

The reason why chinese,mongolian,korean,japanese tend to look alike is because they live in same
climate.However there is an facial distiction among them, you just need to concentrate. Just like there is an distiction among swedish and italians.Although both are classified as white regardless.Btw the vietnamese especially in the south tend to look more like cambodian,thais. While northen vietnamese tend to look more east asians. The more south you go the more southeast asian you look. Although there always acceptions
Indegious north americans and south americans are genetically very similar.However the north tend to look more east asians, while south americans tend to to look southeast asians.South americans are the result of northern eskimos who migrated to south THOUSANDS OF YEARS AGO.SO WHY DO THEY LOOK SO DIFFERENT? the answer is simple and obvious.If you just look at the map.Btw Native american indians are mongoloid but not asian at all,they've evolved seperatelty from the rest of us.
North americans close to canada
South americans close to mexico,brazil,peru.
