如果你養(yǎng)狗,你可能已經(jīng)有所發(fā)覺,這只汪星人有時(shí)似乎在微笑。
But, of course, we know that dogs don't really smile.
但是,當(dāng)然,我們清楚狗是不會笑的。
That's just how dog mouths appear sometimes,right?
狗狗的嘴有時(shí)會張開,對嗎?
Perhaps, but according to neuroscientist JaakPanksepp of Bowling Green State University, someanimals do laugh.
也許的確如此,但按照博林格林州立大學(xué)神經(jīng)系統(tǒng)科學(xué)家賈克·潘克斯皮的理論,一些動物確實(shí)會笑。
When chimps play, Panksepp notes, they make panting sounds that could be a form of laughter.
當(dāng)黑猩猩玩耍的時(shí)候, 潘克斯皮指出,他們發(fā)出氣喘吁吁的聲音可能就是一種形式的笑聲。
Even rats have a way of laughing-by chirping when they're playing with each other or beingtickled by humans.
即使老鼠也有辦法—彼此嬉戲或被人類逗樂時(shí)候通過鳴叫就可以愉悅自己。
But, if animals do in fact laugh, what are they laughing at?
但是,如果動物事實(shí)上真的在笑,他們是在笑什么?
Scientists have long known that for many animals, life isn't all about hunting, foraging,fighting, and sleeping.
科學(xué)家已經(jīng)知曉對于許多動物而言,生活不僅僅是狩獵,覓食,爭斗及睡覺。
Young animals also play a lot, which suggests that animal laughter is related to playful joy.
年輕的動物也會玩耍,這意味著動物笑的原因與嬉戲快樂有關(guān)。
How is this possible?
這怎么可能?
Human laughter originates in veryancient areas of the brain.
人類的笑聲起源于大腦非常古老的區(qū)域。
This suggests that mammalian brains were wired for playful joy long before the rise of modernhumans.
這表明,哺乳動物的大腦在現(xiàn)代人類崛起前就已經(jīng)對嬉戲快樂有所感覺。
So it's not too much of a stretch to claim that pre-human forms of laughter may exist.
因此,對于可能存在的遠(yuǎn)古人類的笑沒有太多的觀點(diǎn)延伸。
To be clear, it's not certain that animals really laugh like humans, at least not in response tohumor.
需要明確的是,動物的笑不一定像人類一樣,至少不是對幽默的回應(yīng)。
However, many studies suggest that animals are capable of complex emotions such as fear,anger, and even joy and sadness.
然而,許多研究表明,動物本身擁有如恐懼、憤怒,甚至快樂和悲傷等復(fù)雜的情緒。
So your dog's grin may not be a real human-type smile.
所以你的狗狗咧開嘴并不是真正意義的微笑。
But it now seems likely that deep in brain regions that animals share with humans, the abilityfor joy and ancients forms of laughter do exist.
但現(xiàn)在看來動物和人類共享大腦的深處區(qū)域,高興的能力及遠(yuǎn)古笑的形式的確存在。
