大量关于杂交猴的实地报告和持续杂交区的记录表明，自然杂交在非洲猕猴中很常见。这两个理论的考虑和审查的情况下，我们得出结论，parapatric杂交密切相关的allotaxa之间是一个普遍的，通常是自然的过程，其发病率可能会修改人类的影响。同域杂交，物种之间的生态差异足以有重叠的范围，是罕见的，并在猴子往往发生在设置自然或人为栖息地的边缘限制迁移，因此获得无关的同种配偶。虽然同域杂交发生在没有人类干扰的情况下，甚至可能是猕猴进化的创造性力量，但人为栖息地破碎化可能会增加其发生率。与更丰富的形式杂交可能会增加其数量和范围已受到严重限制的物种所面临的威胁水平，无论是自然还是人为的。
Numerous field reports of hybrid monkeys and documented cases of persistent hybrid zones suggest that natural hybridization is common among African cercopithecines. Both theoretical considerations and a review of cases lead us to conclude that parapatric hybridization among closely related allotaxa is a widespread, usually natural process whose incidence may be modified by human influence. Sympatric hybridization, between species ecologically distinct enough to have overlapping ranges, is rarer, and in monkeys tends to occur in settings where natural or anthropogenic habitat edges restrict migration and hence access to unrelated conspecific mates. Although sympatric hybridization occurs in the absence of human disturbance, and may even have been a creative force in cercopithecine evolution, anthropogenic habitat fragmentation may increase its incidence. Hybridization with a more abundant form may increase the level of threat faced by a species whose numbers and range have been severely restricted, either naturally or artificially.
