Like, I know every race in the world is different, blah blah blah, but surely the 'oriental eye' is a result of evolution. We (my housemates and I) thought it could have been due to sunlight but then thered be so man other races with slanty eyes.
Any ideas

You've gotten the theories. I just want to add that I don't think their eyes are slanted. Just take a look at them. Jim z mentioned the thicker layer of skin. I think that is what makes their eyes different from the other races.

Oh my goodness - a valid question, if possibly put in a manner that some people ought to in comparison to (slit eyes), yet why the hell each and every physique is attacking you for being racist is previous me! i think of that they trawl throught those questions searching for words, that as quickly as utilized in a appropriate context prefer purely be somewhat naive, yet all of them swap off THEIR brains and cry 'racist' in unison!!! You lot are pathetic. See previous the wording for as quickly as on your pointless little lives, answer the questions in the event that they are properly worth answering or commenting on, and in case you disagree with wording you are able to possibly gently recommend the asker fairly than being entire obnoxious pillocks!

No one knows for sure. It seems just like a genetic phenomenon which has affected two groups of people: Asians and Bushmen. Because Bushmen inhabit South Africa and their population never mixed with Asians, it seems like it is just something that has occurred randomly on two continents.

I pondered this very question when I was pretty young. I knew that blacks were dark because of their need for extra protection from the tropical sun and that Eskimos were robust to better help them cope with the cold (I am simplifying for brevity). I wondered why Orientals developed an extra fat layer in their eye, resulting in the "slit eyes" which I read was evolved to help cope with cold, yet they retained black hair which seemed to be to cope with sun. It struck me that there is a place where sun and cold are very great, in the Himalaya Mountains. I theorized, to myself, that Oriental race probably evolved in Tibet, and then because they needed a very good technology to survive there, were very successful when they migrated out of there. I discovered decades later that language studies indicated Orientals did indeed come from Tibet and migrated from there.
I see the PC patrol arrived. Actually Asia is a continent and oriental is a race. Asia actually has many races.

Living for a long time in a sandy desert might do it. Wind storms would happen once in a while. Narrower eyes might be a defense against being blinded by blowing dust and sand. I don't know, really. That's just a guess.

The slanted eye you refer to is called an eye with an epicanthal fold. There are theories that support that this is an adaptation to climate.
The maintenance of the epicanthic fold into adulthood in many populations is believed to be an evolutionary defense against both the extreme cold as well as the extreme light that occurs in the Eurasian arctic and north. It has also been suggested that the fold provides some protection against dust in areas of desert such as that found in the deserts of northern China and Mongolia as well as parts of Africa.
There is a wide distribution of the epicanthic fold across the world. It is found in significant numbers amongst Native Americans, the Khoisan of Southern Africa, many Central Asians and some people of Sami origin. The presence of epicanthal folds is common in people of many, though not all, groups of East Asian and Southeast Asian descent. It also occurs sometimes on people of South Asian descent. Due to classic genetics children of a parent with a pronounced epicanthal fold and one without an epicanthal fold will have varying degrees of epicanthal folds as a result.
In Asian cultures, the presence of an epicanthal fold is associated with the lack of an upper eyelid crease, commonly termed "single eyelids" as opposed to "double eyelids". The two features are distinct; a person may have both epicanthal fold and upper eyelid crease, one and not the other, or neither.
In other populations the epicanthic fold goes away when the nasal bridge starts to jut out, pulling the skin causing the epicanthic fold to become taut.(Gould) Unlike other populations, Far East and Southeast Asian populations do not have their nasal bridge project out, resulting in the retention of this childish physical trait.
Tripartite Asian eyes vary because they are adapted to different climates. In the cold climate of the Far East, Far East Asians have more fat on their eyelids which causes an inner eyelid fold. (Coon, paragraph 28) This fat warms the eyes, conserving body heat.(Wilson, paragraph 20)(Hotep, paragraph 4) Conversely, in the hot climates of Southeast Asia and the Indian Subcontinent Tripartite Asians have eyes adapted to heat. These eyes have limited fat above their eyes. This makes their eyeballs look sunken into their skull and the spherical shape of their eyes to stand out clearly.

They are called "Asians," not "orientals." RUGS are oriental, people are Asian.(I'm not trying to be a condescending "know-it-all," but many Asian people get offended if they are referred to as "Oriental," just thought you should know.) More than likely the eye shape is a genetic variant that became dominant in the regions populated by their ancestors. There is most likely no evolutionary purpose for this eye shape, just as there would be no purpose for round eyes, almond eyes, etc.

I image whatever race of people lived in colder climates needed to protect their eyes. Asian people and certain Indians and Eskimos probably came from the same people.

It has always been blamed on the bright sun, but I have my doubts also. Good luck. Pops
