性行為當前的含義 3:
生殖行為 |

高等哺乳動物的生殖行為 |
|

在高等哺乳動物，性行為的天生固有的生理機制尚不足以保證雌雄動物“成功地”性交合，而必須通過後天學習才得以加強。例如，一些猴類和猿類動物以隔離的方式所飼養，它們沒有機會觀察或實踐交尾行為，直到它們對突然現身的夥伴的“性信號”做出反應時，才會擁有交尾的能力，但是它們也許並不知道如何與夥伴進行性交合。它們的身體動作仍然笨拙不堪和失之協調。其結果是受精便不能發生。因而，顯而易見，這些動物“正常的”性行為極大程度上依賴於練習和體驗。此外，研究成果清楚地顯示，許多高等哺乳動物的性行為類型繁多和行為細節分化相當地大，並且不只是用來完成生殖功能。它們的性行為也有助於維持動物群落的聯繫紐帶和相互的協調。 |

Current Meanings of the Term 3: Reproductive Behavior

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.
