Dr. Williamson’s group reported that a version of a gene called DAB1 had become universal in Chinese but not in other populations. DAB1 is involved in organizing the layers of cells in the cerebral cortex, the site of higher cognitive functions.
除此之外，混血兒將喪失中國人一個獨特的DAB1優勢基因，導致混血兒智商低於一般中國人
我想每個人種都有自己獨特的優缺點..混血兒等於是同時放棄優點與缺點...
大自然本身是靠物競天擇的在演化，只想靠混血就來提高，本身就是天方夜譚的想法
