I started doing some research then, and this was the 25-year journey, and started finding out that actuallyhuman beings as primates have far smaller stomachs than should be the size for our body weight and far larger brains.And as I went to research that even further, I got to a point where I discovered something called the expensive tissue hypothesis.That actually for a given body mass of a primate the metabolic rate was static. What changed was the balance of the tissues available.And two of the most expensive tissues in our human body are nervous tissue and digestive tissue.And what transpired was that people had put forward a hypothesis that was apparently coming up with some fabulous results by about 1995.It's a lady named Leslie Aiello. And the paper then suggested that you traded one for the other.If you wanted your brain for a particular body mass to be large, you had to live with a smaller gut.That then set me off completely to say, Okay, these two are connected.So I looked at the cultivation of information as if it were food and said,So we were hunter-gathers of information. We moved from that to becoming farmers and cultivators of information.
