Do Eskimos have high IQ?

Why do Eskimos in cold areas have low IQ? Lynn's explanation is that in the process of early African Homo erectus migrating to other parts of the world, it carried genes that could evolve high IQ and low IQ. And this gene has more chances to evolve in areas with fast population development and large population. Eskimos are vast and sparsely populated, so the chances of genes controlling IQ mutating into high IQ are less than those in Eurasia. Until today, the total population of Eskimos is only 55,000.

We can't deny that the genetic diversity in Jiangsu and Zhejiang is obviously more than that in the north. According to gene theory, the communication with large genetic differences is beneficial to human evolution. As you can see, the big cities in the south, such as Shanghai 109, Jiangsu 107 and Hong Kong 107, have the highest values, from which we can draw a conclusion that intelligence lies in communication.
