Marmosets are small primates.
絨猴是小型靈長類動物。
Think of a monkey with huge fuzzy ears.
想象一只有巨大、毛絨絨耳朵的猴子。
Primatologists have often wondered whether nonhuman males evaluated their potential mates,or whether their sex drive was more like an on/off switch.
動物學家時常困惑：雄性動物選擇“另一半”或者控制性欲是否更像是一個開關(guān)鍵。
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.
我們可能認為動物只是不假思索地對性邀請做出反應(yīng)，但美國和德國的一項研究表明，事實并非如此。
Male marmosets having their brains scanned were given sniffs of genital-gland secretions from ovulating females.
雄性絨猴開始用大腦掃描，嗅著正在排卵的雌性動物生殖腺的分泌物。
That's a scent that should trigger a mating response in the brain, and it did!
這種氣味會引起大腦里的交配反應(yīng)，這樣它們才會進行交配。
But guess what else happened?
但你猜還會發(fā)生什么情況?
