性行为当前的含义 3:
生殖行为 |

高等哺乳动物的生殖行为 |
|

在高等哺乳动物，性行为的天生固有的生理机制尚不足以保证雌雄动物“成功地”性交合，而必须通过后天学习才得以加强。例如，某些猴类和猿类动物以隔离的方式所饲养，它们没有机会观察或实践交尾行为，直到它们对突然现身的伙伴的“性信号”做出反应时，才会拥有交尾的能力，但是它们也许并不知道如何与伙伴进行性交合。它们的身体动作仍然笨拙不堪和失之协调。其结果是受精便不能发生。因而，显而易见，这些动物“正常的”性行为极大程度上依赖于练习和体验。此外，研究成果清楚地显示，许多高等哺乳动物的性行为类型繁多和行为细节分化相当地大，并且不只是用来完成生殖功能。它们的性行为也有助于维持动物社群的联系纽带和相互的协调。

Higher Mammals

|
|
In the higher mammals, the inborn physiologic controls of sexual behavior are not sufficient to guarantee "successful" mating, but have to be augmented by learning. For example, monkeys and apes raised in isolation who had no opportunity to observe or practice copulation still possess the capacity to respond to the cues of suddenly appearing partners, but may not know how to interact with them. Their body movements remain clumsy and inappropriate. As a result, fertilization cannot take place. Thus, it is obvious that the "normal" sexual behavior of these animals depends, to a great extent on training and experience. Furthermore, it is clear that
the sexual behavior of many higher animals is quite varied and elaborate and serves more than a mere reproductive function. It also helps to maintain social coherence and coordination.
