pheromone

As they groom themselves, the tears—and the pheromone—get spread around their bodies and nests.

随着他们刷洗全身，眼泪——还有信息素——就会散布到它们的全身和窝里。

Although the classical pheromone pathway in both Old World primates and humans is dysfunctional, the mechanism for producing pheromones still works.

虽然在古代灵长类和人类身上，这种典型的信息素途径失去了作用，制造信息素的功能还继续存在。
