Biology is a software process. Our bodies are made up of trillions of cells, each governed by this process. You and I are walking around with outdated software running in our bodies, which evolved in a very different era.
The ethical debates are like stones in a stream. The water runs around them. You haven't seen any biological technologies held up for one week by any of these debates.
The software programs that make our body run ... were evolved in very different times. We'd like to actually change those programs. One little software program, called the fat insulin receptor gene, basically says, 'Hold onto every calorie, because the next hunting season may not work out so well.' That was in the interests of the species tens of thousands of years ago. We'd like to turn that program off.
What we found was that rather than being haphazardly arranged or independent pathways, we find that all of the pathways of the brain taken together fit together in a single exceedingly simple structure. They basically look like a cube. They basically run in three perpendicular directions, and in each one of those three directions the pathways are highly parallel to each other and arranged in arrays. So, instead of independent spaghettis, we see that the connectivity of the brain is, in a sense, a single coherent structure.
