India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples. The grand mediocrity of today —everyone being the same in survival and number of offspring — means that natural selection has lost 80% of its power in upper-middle-class India compared to the tribes.

　　参考译文

　　印度的情况可以说明正在发生的一切。这个国家为大城市的少数人提供了财富，而给予其余的各部落人民以贫穷。今天这种大规模的均一化——每个人在存活几率和子女数量方面都相同——意味着与部落相比，自然选择在印度中上阶层已经失去了80%的作用。
