摘　　要：同性间爬跨行为在非人灵长类动物中普遍存在。对 30种灵长类的研究认为 ,该行为发生是正常的 ,具有一定的社会功能。其社会功能有 :1 )玩耍 ,多见于少年个体 ;2 )侵犯 ,发生在群体中具有社会等级关系的个体之间 ,爬跨者通过爬跨对被爬跨者进行安慰 ,或加强其优势地位 ;3)性兴奋 ,常发生在交配高峰期 ,同性爬跨可能是找不到异性对象所致 ;4 )打招呼 ,此过程不涉及插入 ,只是身体接触 ,行为持续短暂 ,表现温和友好 ;5 )性技能训练 ,这是一种人为推测 ,尚未得到证实。Homosexual mounting behavior has been reported in 30 non-human primate species both in captivity and in the wild, but it was usually considered to result from stressful and abnormal conditions or from misapplication of the term “homosexual' to sex-derived ritualized patterns. Its social functions were summarized as follows: 1) Play, occurs more common in young, often in play, than in adults; 2) Aggression, often correlated with dominance among males, and sexual conditions in females; 3) Sexual excitement; 4) Physical contact; 5) Sexual skill training. Five reasons were listed in the article, but there is some overlap between the categories.
