时差N小时 猴子如何示爱?(上)（在线收听）

Marmosets are small primates.

绒猴是小型灵长类动物。

Think of a monkey with huge fuzzy ears.

想象一只有巨大、毛绒绒耳朵的猴子。

Primatologists have often wondered whether nonhuman males evaluated their potential mates, or whether their sex drive was more like an on/off switch.

动物学家时常困惑：雄性动物选择“另一半”或者控制性欲是否更像是一个开关键。

We may think of animals as just responding to sexual invitations without thinking, but a study conducted in both the U.S. and Germany shows this isn't necessarily so.

我们可能认为动物只是不假思索地对性邀请做出反应，但美国和德国的一项研究表明，事实并非如此。

Male marmosets having their brains scanned were given sniffs of genital-gland secretions from ovulating females.

雄性绒猴开始用大脑扫描，嗅着正在排卵的雌性动物生殖腺的分泌物。

That's a scent that should trigger a mating response in the brain, and it did!

这种气味会引起大脑里的交配反应，这样它们才会进行交配。

But guess what else happened?

但你猜还会发生什么情况?
