1. Is it plausible that the developing brain never evolved to cope with exposure to maltreatment and so is damaged in a nonadaptive manner? 难道说，发育中的脑袋就从未演化出应付不幸遭遇的办法，以至于不能适应这些不幸而遭到伤害？
2. Such nonadaptive chance evolution may be quite rare. But geologic time is so vast, as Darwin himself pointed out, that species pass through countless generations over millions of years. 尽管这种违反适者生存原则的变化很可能是一种极少有的情况，但是正如达尔文本人曾经指出的那样，地质时期是如此之长，以致一个种在亿万年间会经过无数世代。
