解析：
关于人类智慧发展的原因，录音中描述了两个理论：“Machiavellian mind”和“mating mind”。在讲到后者时，录音中指出“…the “mating mind”, is that much of human intelligence is about showing off to the opposite sex, in a behavioral equivalent of the peacock’s tail”，因此题干有误。
【录音原文】
Why human intelligence evolved in the first place is controversial. Many researchers feel that it was not so much to deal with the non-human world (e.g., predators and food-gathering) as to deal with other people. One theory, known as the “Machiavellian mind”, is that intelligence is there to analyse, and thus manipulate, the motives of others. Another, known as the “mating mind”, is that much of human intelligence is about showing off to the opposite sex, in a behavioral equivalent of the peacock’s tail. Both could be true. Whether either of these purposes would disappear on an island is moot.
