絨猴是很小的靈長(zhǎng)類。

Think of a monkey with huge fuzzy ears.

試想一下，猴子長(zhǎng)者一對(duì)大大的毛絨絨的耳朵。

Primatologists have oftenwondered whethernonhuman males evaluated their potential mates,or whether their sex drivewas more like an on/offswitch.

動(dòng)物學(xué)家時(shí)常有這樣的疑惑：雄性動(dòng)物選擇“另一半”或者控制性欲是否更像是一個(gè)開關(guān)鍵。

We may think of animals as just responding to sexualinvitations without thinking, but a studyconducted in both the U.S. and Germany shows thisisn't necessarily so.

我們也許會(huì)認(rèn)為動(dòng)物對(duì)于性邀請(qǐng)基本是不假思索的，但最近美國(guó)和德國(guó)有研究稱事實(shí)并非如此。

Male marmosets havingtheir brains scanned were given sniffs of genital-gland secretions fromovulating females.

雄性絨猴用它們的大腦掃描，聞?wù)谂怕训拇判詣?dòng)物生殖腺的分泌物。

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

有一種氣味會(huì)引起大腦里的交配反應(yīng)，這樣它們才會(huì)進(jìn)行交配。

But guess what elsehappened?

但你猜還會(huì)發(fā)生什么情況?

Many other brain areas lit up as well, such as memory formation, informationintegration–inother words, areas associated with decision-making.

很多其它的大腦葉都會(huì)被“激活”，像信息形成，信息整合，也就是說(shuō)，所有和決策相關(guān)的區(qū)域。

Researchers are still studying the effect, but apparently a lot more happens in a marmosetbrainthan a simple “have sex now” program.

研究人員還在觀察其影響，但很顯然，絨猴的腦部有很多活動(dòng)而不是一個(gè)簡(jiǎn)單的“性行為”指定。

The specific areas of brain activity suggest that the malesare evaluating potential matesbefore agreeing to a sexual union.

特定區(qū)域的大腦活動(dòng)暗示雄性絨猴在性結(jié)合之前會(huì)評(píng)估潛在的交配對(duì)象。

This makes special sense for marmosets, because they are monogamous and both partners raisethe offspring.

這對(duì)于絨猴有特殊的意義，因?yàn)樗鼈兪菃闻渲?，并且共同撫養(yǎng)后代。

Under those circumstances you wouldn't want to enter into a relationship without any thought.

在這種情況下，就不會(huì)不假思索地介入這段關(guān)系了。
