This is a loaded question, but based on DNA, they have have actually come from Southeast Asia, then India, then Arabian Peninsula then from East Africa before that. This may be based on studying genetic diversity.
East Asian and Europeans have a common ancestor somewhere in Eurasia before splitting off some 40,000 years ago (as what I have read).
Yes . But the evolution of distinctive East Asian traits where did it occurred??
Siberia?? Mongolia?? It seems a cold place of continuous ice

Where did the East Asian feature come from or first appear? Again, this is all speculation. I know, again we are deviating from your original post about what latitude we live in (in relation to Europe). I don’t think they came from Eskimos. I have read up on this subject in various places.
I personally believe it first appeared in Southeast Asia, then the feature further developed in East Asia somewhere perhaps in China. There is something called Sundadont and Sindodont-that has something to do with the jaws and teeth that are unique to people in Southeast Asia and East Asia. (See: Sinodonty and Sundadonty - Wikipedia, the free encyclopedia) I think it may relate also the skull formation. In general, East Asians have higher checkbones, lower nose bridges compared to Europeans who have narrower faces, higher nose bridges and pointer or stronger chins.
It has been speculated East Asians came from Southeast Asia. The Sundadont (dental type) first appeared there. The name comes of Sundaland (See: Sundaland - Wikipedia, the free encyclopedia ) which was the landmass of Southeast Asia when sea levels were lower. While Sindodont (literally means “Chinese teeth”). The Sundadont features appeared first, then when people migrated to East Asia, the Sindodont features emerge out of the Sundadont. There is evidence the Sundadont feature is older than the Sindodont. This may correspond to Proto Mongoloid features which came earlier than the Neo Mongoloid features which is more predominate among the Chinese, Japanese (though the Ainu people of Japan are more Proto or Paleo Mongoloid), Koreans. (See: Mongoloid - Wikipedia, the free encyclopedia) The Neo Mongoloid feature may have developed from the Proto Mongoloid and deviate due to climate (Neo-Mongoloid features may be more cold adapted than the earlier Mongoloid from Southeast Asia), environment, genetic drift/mutation, and sexual selection (e.g., some males may have thought the Neo Mongoloid feature were attractive and chose mates with those features- further spreading the population- I have heard something similar regarding blond hair in Europeans- it first appeared via a mutation, but then further spread because some people thought those features were attractive and choosing mates with that). There is also something called neoteny which developed in East Asians which I am not sure why that developed-neoteny may results in a more youthful appearance- larger heads, smaller nose, higher cheekbones). (See: http://en.wikipedia.org/wiki/Neoteny)- read that article as it has some interesting theories.
Ok, sorry for deviating from the original subject, but responding to your question. Perhaps you can also post your questions on the Asia section of this forum.
The Almond shaped eyes isn't unique to Asians it can be found in Africa among some ethnic groups same with the blond hair gene, a Nigerian mother gave birth to a blue eyed, blond eyes baby.
Those genes are embedded in Africans, when Homo Sapiens migrated out of Africa around 70,000 years ago some traits were more useful than others, those traits didn't ''evolve'' evolving means evolving means mutating we didn't mutant!
True, the San people in Africa supposedly one of the oldest people in the world (having the most genetic diversity among people around the world) have "almond shaped eyes" See: San people - Wikipedia, the free encyclopedia where you can view photos of them.
In terms of blond hair or blue eyes-yes they are not unique to Europeans. However, the SNP (single nucleotide polymorphism) that gave rise to it in Europeans are different from say people from Papua New Guinea or the Australian aborigines. They arose independently of each other, but I do agree with your point that since Africans such as the San people have the most genetic diversity-these traits were in them genetically and would give rise when people migrated out of Africa due to various conditions. See: https://www.google.com/search?q=blon...w=1280&bih=891
There are also reported some people in Afghanistan with light color eyes, but I think they are partially descendant of the Eurasian group of people who gave rise to Europeans
There are Mongolians and Kazakh people with green eyes with seemingly Mongol features. I believe they may have some mix, as they are close to the Silk Road. See: https://www.google.com/search?q=mong...w=1280&bih=891
