时差N小时:干净的东西更美味?(下)

Infants in the next generation saw their motherswashing potatoes, and virtually all the nextgeneration, both male and female, grew up washingtheir food, but not the older males! Older males wereresistant to the new idea, refusing to wash theirfood even when older females made the change. Itwas as if a new idea from a female, or perhaps alower-ranking member of macaque society, wererejected by older males even though it was a goodidea. They seemed to choose eating sand rather thanadmitting Imo was smarter than they were.

下一代的幼猴看到他们的母亲洗土豆，几乎所有的下一代，无论雄性还是雌性，长大后都会洗食物。但老年雄候不会那样做!老年雄候不赞成洗食物的做法，甚至老年雌候改变时，他们同样会拒绝洗食物。似乎是这样：如果一个新的想法来自一个雌猴，或者一个较低级别的猕猴社会成员，即使那是一个好主意，老年雄猴也会拒绝。他们似乎宁愿选择吃沙子也不愿意承认Imo比他们聪明。
