　　There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women have 15 children. Nowadays the number of births, like the age of death, has become average. Most of us have roughly the same number of offspring. Again, differences between people and the opportunity for natural selection to take advantage of it have diminished.

　　【参考译文】进化自杀还有另外一种办法：活得更久，但少生孩子。现在很少有人像过去那样那么能生育。除了在少数宗教团体中，几乎没有女性生15个孩子。现在生育的人数，就像死亡的年龄一样，变得平均化。我们大多数人的子女数大致相同。又一次，人与人之间的差异性和利用其(差异性)进行自然选择的机会已经减少了(自然选择在人与人之间几乎不起作用)。
