To ascertain the social significance of male genital colouration two troops of vervets, one free-ranging and one caged, were observed. It was found that genital signals were associated with intermale agonism. It is suggested that this communicatory system regulates the behaviour of competitors and may thereby have facilitated the evolution of a multimale social system.
为了确定雄性生殖器颜色的社会意义，观察了两群绿猴，一群自由放养，一群圈养。研究发现，生殖器信号与雄性间的争斗行为有关。有人认为，这种交流系统调节着竞争者的行为，从而可能促进了多雄性社会系统的进化。
