Language and Humanity
語言和人類
Good morning, everyone.
大家早上好。
In today's lecture, we're going to discuss the relationship between language and humanity. As we all know, language is very powerful.
在今天的課上，我們將討論語言和人類之間的關(guān)系。眾所周知，語言是非常強大的。
It allows you to put a thought from your mind directly in someone else's mind.
它可以讓你把你的想法直接放在別人的大腦里。
Languages are like genes talking, getting things they want.
語言就像會說話的基因，得到他們想要的東西。
And you just imagine the sense of wonder in a baby when it first discovers that, merely by uttering a sound, it can get objects to move across a room as if by magic, and maybe even into its mouth.
你可以想象，當一個嬰兒第一次發(fā)現(xiàn)，僅僅通過發(fā)出一個聲音，它就能讓物體像中了魔法一樣在房間里移動，甚至可能進入它的嘴里。
Now we need to explain how and why this remarkable trait, you know, human's ability to do things with language, has evolved, and why did this trait evolve only in our species?

In order to get an answer to the question, we have to go to tool use in the chimpanzees.
為了得到這個問題的答案，我們必須研究黑猩猩的工具使用。
Chimpanzees can use tools, and we take that phenomenon as a sign of their intelligence.
黑猩猩可以使用工具，我們把這種現(xiàn)象作為它們智力的標志。
But if they really were intelligent, why would they crack open nuts with a rock?
但如果他們真的聰明，他們?yōu)槭裁匆檬^砸開堅果呢？
Why wouldn't they just go to a shop and buy a bag of nuts that somebody else had already cracked open for them?
他們?yōu)槭裁床蝗ド痰曩I一袋別人已經(jīng)打開的堅果呢？
Why not? I mean, that's what we do.
為什么不呢？我是說，我們就是這么做的。
