Look – All I can say, it's early days. One group in Holland has been trying to work on that. But it's... I'm a theoretician, so I run away from experimental problems. So I can't deal with – can't make experimental suggestions as to how that might be done. But all I'm saying is we at least have an outline, a direction to think about in order to somehow create –

a system that could, once it replicates, it can evolve. And let me say here clearly, once it evolves, it will evolve in a direction that complexifies, that leads to not simplicity, but to complexity, because just as the second law is quantitative, there is a tiny quantitative element to the DKS system as well.

When you do the differential equation that describes the formation of a system in the decay state, it's just the predator, the classic predator-prey equation, formation and decay. But once you have two... DKS systems competing for the same resource, the math says quite explicitly that the more stable, the more persistent one will drive the less persistent one into extinction.

In other words, once you have a mutation in the DKS system, it will drive, it will be encouraged, and it'll push away. It, if you like, saps the water out of the other fountain, so the other fountain just collapses. And what will it do? it will take on characteristics that enable it to deal better with its environment.

So here is the beginning of memory, because the fact that it changes in a way that makes it more stable, that greater stability is not inherent to the system. It's environmentally dependent. It's stable for that particular environment. Just like, you know... A tiger might be stable in Africa, but if you put him in Alaska on an iceberg, it's not doing too well.

The thing that has to be stated is that that will only happen for a limited period of time as long as energy is available. Once the energy stops, everything stops. Now, look, the fact that we build houses, we build lots of things, that's all counter thermodynamic because we're utilizing energy in order to bring about these systems that are counter thermodynamic.

But we can only do that as long as energy is available. And most of the energy that enables life to proceed and develop on Earth is solar energy. Once the solar energy stops, and that will happen eventually, then all life will, just like if you stop pumping water into your fountain, the fountain will die and all of life in that same way will die.

It'll collapse because you don't have the source of energy. So there'll be no life when we get to that state you physicists love to talk about, heat death. It's not going to be fun there. We won't have any No pleasure in being in heat, dear.

I have to say that my understanding from the work of people in the field that making these DKS chemical systems is not easy. And that has to be worked on more as well. And I can't comment too much on that because... I'm the guy that doesn't dare go into the lab. So I can't say much on that. But just to say that it is being done, but the systems that arise have an extraordinary –

Dynamic capability, flexibility, because as I say, the fact that for every thermodynamic state there are thousands of kinetic states means that once there's a driving force for change, and there is one, and we'll talk about that in a moment maybe because it's very important, Because biologists tend to think of evolution as without direction. That is not true. Evolution definitely has a direction.
