A polymer is when two ping-pong balls, if you like, are able to come together and rather than bounce off one another they connect and then there’s two ping-pong balls connected together, so you have double the information before and so on, and you get the sort of daisy-chaining. Nothing is ‘truly’ random. That’s the point. But the reason I sent it to you is that it has two full chapters, 5 and 6, which is about a new theory of biological evolution, which places this in an entirely new context. Absolutely so, and that’s why I say DNA requires teleology first. What do you reckon about that, Perry? Our immune systems are doing that now as we talk.If a new invader comes and invades our body – another virus or bacterium that we haven’t met before – what do we do? We await his submission.
I like Sarah Walker, of course, who you co-authored that paper with.Just for everybody’s benefit, what pathway assembly says is there’s a certain minimal set of instructions necessary to assemble chemicals in certain orders and certain sequences. You’re not going across the ocean in that.So what I’m trying to find out is the lineage of chemistry that makes the most primitive rubbish machine that isn’t a machine, it’s a random ensemble, but as soon as that random mess is able to copy itself – and we’ve actually got one, I’m just publishing it right now – salt that makes itself, actual table salt that can self-replicate from nothing.Think about that for a second. They’re both very excited that this occurs because the autocatalytic sets today – I’ll tell you about them quickly for your listeners.An autocatalytic set is a bit like a mutual carpenter. If you’re not subscribed to the channel, go and do that because you’ll join thousands of people who are doing that these days, and watching these shows on video as well.Can chemistry crack the mystery of the origin of life?

It will be interesting to see how the Discovery Institute and its allied publications and affiliates spin this discussion.The part that sets me off and this is when he says it’s evolving UD did a piece on this a while back toThat article is based on a paper that is over 10 years old.There is now a coronavirus case at Lackland Air Force Base, where I did basic training many decades ago.A living cell is a description based organization; having the dynamic freedom to describe itself as well as any variation of itself. That’s the idea, yes indeed, and there is evidence for that because some of the meteorites that have come down onto earth from somewhere up there – we don’t know where from – contain organic chemicals and they can contain up to 70 different amino acids. Together with concepts and tools developed in other areas of nonequilibrium physics, significant progress has been made in unraveling the principles underlying efficient energy transport in photosynthesis, cellular regulatory networks, cellular movements and organization, embryonic development and cancer, neural network dynamics, population dynamics and ecology, as well as aging, immune responses, and evolution. First of all, the code itself between the sequence of DNA and sequence of proteins we know, as Perry has already referred to, that particular triplets n important fact about that code is its redundant. Now if you want to have a handle that is ‘credible’ might I suggest “Robert Boyle” as a handle? What’s the benefit of that happening? Those stars burned, exploded, and produced carbon, and that carried on, which produced some heavy ele and the material on those planets turned into biology.I agree with Perry about being annoyed and confused by the assertion that life was a happy chemical accident. You’re one of the judges as well. Because inevitably we tend to anthropomorphize this salt as though, “Oh, the salt wants to do this and it’s going to….” and that’s unhelpful, isn’t it. We speak different languages, so I’ll let the chemists duke it out about chemistry.a lot of origin of life people make it sound as though, “All we need to do is get a little replicator started and it’s all going to go from there,” and most of the time they’re being dishonest even about the word ‘replicator.’ If you want to replicate the way a cell does, you have to have symbolic code that stores information about how the organism is supposed to be put together, and that’s completely different than RNA strands making copies of each other, which is like crystals forming.I’ve got to say there’s a lot of dishonesty in the origin of life field, and James Tour and I at least salute him for doing that.
It gives you a metric and then says, “There’s this thing called life.

That’s what the spot on Jupiter also tells us. Now, there is a theory that some forms of life can go completely dry and survive in space. Cronin highlights the inception of a new programmable robot for molecular discovery with the aim of ushering in a new golden age of reproducible, open-source chemistry to save thousands of hours of time spent on repetitive routine chemical syntheses. I had mentioned the Unbelievable programme in another thread and thought I’d talk it up again.“How many more questions do you want me to answer before you respect your side of the deal?”So what now, you want me to go through Martin_r’s statements and tell you exactly what I disagree with? I think that’s got the point.

In fact, maybe Lee and James could have a debate on this show.

When something from that randomness finds a use, it is then trapped and promoted, and that process is the emergence of encoding and decoding.It’s so super exciting because I think I will be able to convince Perry and Denis and anyone else who cares that we’ve got systems that can do that. It’s a really interesting way of putting it.
