I started doing some research then, and this was the 25-year journey, and started finding out that actually
我從那時起開始從事相關的研究，到現在已經二十五年了我最早的發現就是
human beings as primates have far smaller stomachs than should be the size for our body weight and far larger brains.
若以體重為標準，身為靈長類動物的人類胃很小，大腦卻很大。
And as I went to research that even further, I got to a point where I discovered something called the expensive tissue hypothesis.
深入研究之后我發現了一種名為昂貴組織的假說。
That actually for a given body mass of a primate the metabolic rate was static. What changed was the balance of the tissues available.
這種假說認為：對于一定體重的靈長類動物來說新陳代謝率是一定的。不同的是體內各種組織的平衡。
And two of the most expensive tissues in our human body are nervous tissue and digestive tissue.
而人體內兩種最為昂貴的組織是神經組織和消化組織。
And what transpired was that people had put forward a hypothesis that was apparently coming up with some fabulous results by about 1995.
因此人們提出了一個假設，1995年的時候這個假設衍生出了不少精彩的成果。
It's a lady named Leslie Aiello. And the paper then suggested that you traded one for the other.
這些成果背后的功臣是一位名叫LeslieAiello的女士。
If you wanted your brain for a particular body mass to be large, you had to live with a smaller gut.
相關的論文顯示，胃和大腦，不可兼得。在體重一定的情況下，如果你希望擁有更大的大腦的話，就只能擁有一個比較小的胃。
That then set me off completely to say, Okay, these two are connected.
這種觀點讓我確信食物和信息一定有關聯。
So I looked at the cultivation of information as if it were food and said,
因此我把信息當成食物，研究了它的生產過程我的結論是，
So we were hunter-gathers of information. We moved from that to becoming farmers and cultivators of information.
我們都是信息的捕獵者和采集者。后來我們逐漸成為培育信息的農民和生產者。
