Some modern anthropologists hold that biological evolution has shaped not only human morphology but also human behavior. The role those anthropologists ascribe to evolution is not of dictating the details of human behavior but one of imposing constraints—ways of feeling, thinking, and acting that “come naturally” in archetypal situations in any culture. Our “frailties”—emotions and motives such as rage, fear, greed, gluttony, joy, lust, love—may be a very mixed assortment, but they share at least one immediate quality: we are, as we say, “in the grip” of them. And thus they give us our sense of constraints.
Unhappily, some of those frailties—our need for ever-increasing security among them—are presently maladaptive. Yet beneath the overlay of cultural detail, they, too, are said to be biological in direction, and therefore as natural to us as are our appendixes. We would need to comprehend thoroughly their adaptive origins in order to understand how badly they guide us now. And we might then begin to resist their pressure.
--------------------------
It can be inferred that in his discussion of maladaptive frailties the author assumes that
(A) evolution does not favor the emergence of adaptive characteristics over the emergence of maladaptive ones
(B) any structure or behavior not positively adaptive is regarded as transitory in evolutionary theory
(C) maladaptive characteristics, once fixed, make the emergence of other maladaptive characteristics more likely
(D) the designation of a characteristic as being maladaptive must always remain highly tentative
(E) changes in the total human environment can outpace evolutionary change

----------------
答案是E。
求解释为什么A不能？

这个选项： evolution does not favor the emergence of adaptive characteristics over the emergence of maladaptive ones

文章只告诉了我们进化会给我们带来很多不相容的限制。并没有说一定不会带来相容的特性，不要脑补哦。GRE从来是有一说一，有二说二。
