"Selfish," when applied to genes, doesn't mean "selfish" at all. It means, instead, an extremely important quality for which there is no good word in the English language: "the quality of being copied by a Darwinian selection process." This is a complicated mouthful. There ought to be a better, shorter word – but "selfish" isn't it.

所以，所谓的什么“自然选择，强者生存”是完全不成立的。

而谈论到人类社会、文化的演化，则完完全全是另外一个层面的领域。如果用自然演化的成功和失败来衡量社会的成功和失败，那中国和印度可能是世界上最成功的国家。
