The higher IQ of yellow race people in Northeast Asia is caused by many factors such as heredity, environment and social choice.
The yellow race in Northeast Asia with Y chromosome O mutation may have more advantages in cognition and coping with the environment.
In cold regions, human intelligence to cope with environmental challenges will be significantly enhanced in evolution.
At the same time, the attention paid by East Asian society to education and knowledge makes people more curious.
Gene difference theory is an important reason for the international differences in IQ and cognitive level. These genetic differences are supported by evolutionary theory and a large number of IQ test data. Genetic differences are not the only reason, but also environmental factors.
The genetic changes caused by temperature changes are stronger among IQ-related genes than those caused by other environmental factors. A colder environment is considered to have more cognitive needs than a milder environment.
A related but different theory is the difference K theory (high K chooses R-k theory in human beings; Rushton, 2004, Rushton, 20 12), which points out that a more stable environment, such as that found in East Asia in the north and northeast of the world, promotes the evolution of cognitive mechanism to predict the future situation and take precautions.
In this time span of 6.5438 million years, those primitive people in Africa stayed in a warm environment, made no progress, did not increase their IQ, and did not evolve advanced civilization. The ancestors of the yellow race are farther and farther away from the African continent, constantly coping with the challenges brought by various strange and harsh environments, and constantly enhancing their advantages in cognition and coping with the environment in complex environments.
In the process of migration and evolution, the IQ of the ancestors of the yellow race has been greatly improved.
The brain capacity is getting bigger and bigger, and the yellow race in Northeast Asia has the largest brain capacity, nearly 200cm3 more than that in Kenya. At the same time, in order to improve the intelligence level of future generations, the ancestors of the yellow race have the lowest fertility, and the children of the yellow race have the slowest development, taking longer to walk and run, and the slowest sexual maturity.
It takes the longest time and cycle to learn and recognize new things, and the skin aging is slower, followed by white children, black children have the fastest development, the fastest sexual maturity and the shortest time to learn and recognize new things. These are the wealth left by the ancestors of the yellow race in Northeast Asia who fought against nature from generation to generation and continued to evolve.
It makes the yellow race evolve more and get rid of the primitive state of animals, and makes the descendants of the yellow race develop more slowly, mature more slowly, and learn and know new things for a longer time.
