East Asians are the indigenous people of China, Japan and Korea.
In classical anthropology, these peoples were recognized as one of the major races in the early taxonomies of Linnaeus (1758) and Blumenbach (1776) and are one of the seven major races in the classification proposed by Coon, Garn and Birdsell (1950).
Their identity as a genetic “cluster” was confirmed by CavalliSforza, Menozzi and Piazza (1994). The most distinctive features of East Asians are their straight black hair, flat noses, yellowish skin color, and the epicanthic fold that gives their eyes a narrow appearance.

East Asians (Mongoloid) are natives of China, Japan, Korea and Taiwan. They also populate mainly Singapore (which explains the high average I.Q of this state).
The median value is 105.

4. I.Q and Brain Size of East Asian-European Hybrids
The mean I.Q of hybrids and their cranial capacity are intermediate between those of Europeans and those of Mongoloid, as we could expect.
5. East Asians-Europeans Differences in Reaction Time
Mongoloids have a faster reaction time than Europeans, consequence of the positive correlation between I.Q and reaction time.
6. Brain Size of East Asians
Only Gould finds an absence of difference, but we know that Stephen J. Gould has many times delicately deceived his results to support his egalitarian ideology. A new measurement of skulls analyzed by Gould also found a significant difference.
