As I said at the beginning, language really is the voice of our genes. 正如我一开始所说的，语言确实是我们基因的声音。
But, as we spread out around the world, we developed thousands of different languages. 但是，我们散落到世界各地，发展出数千种不同的语言。
Currently, there are about seven or eight thousand different languages spoken on Earth. And then another problem occurred. 目前，地球上大约有七千到八千种不同的语言。然后另一个问题出现了。
It seems that we use our language, not just to cooperate, but to draw rings around our cooperative groups and to establish identities, and perhaps to protect our knowledge and wisdom and skills from being stolen from outside. 似乎我们使用语言，不仅仅是为了合作，而且是为了围绕我们的合作群体建立联系，建立身份，也许是为了保护我们的知识、智慧和技能不被外界窃取。
And we know this because when we study different language groups and associate them with their cultures, we see that different languages slow the flow of ideas between groups. 我们之所以知道这一点，是因为当我们研究不同的语言群体并将他们与他们的文化联系起来时，我们发现不同的语言阻碍了群体之间的思想交流。
Okay, this tendency we have, this seemingly natural tendency we have, goes towards isolation, towards keeping everything to ourselves, whereas our modern world is communicating with itself and with each other more than it has at any time in its past. 好了，我们的这种倾向，这种看起来很自然的倾向，趋向于孤立，趋向于把所有的东西都留给我们自己，而我们的现代世界更多的是在和自己交流，和彼此交流，比过去任何时候都要多。
