You're talkin about either meteors hitting or comets or something,

you know, volcanic o we think the rments were very volcanically active. There having been lava floes would be something very common that can transform the perasinides. Ony later on, things cool down, rain falls dissolves these compounds again into a shallow lake, a pond. Now we're a little closer to darwin's a warm little pond. And now sunlight has a critical role beca the many, many photo chemical reactions that are needed, at least in the southerland chemistry, to bring you up to the level of nucletides, meno acids, lipids. But essentially, the ideas you make all f these compounds from cyanide incredible.

So maybe we should return then to this theme of, you know, now that we've got syanide world, we can somehow go up are in a world, except that, apparently, that's, that's a big mystery still, right? Well,

i think th the pathway to get into two of the four building blocks of arna is maybe 90 % worked out. And i'd say one of the biggest steps. We have all this energy from sunlight, right? But the question is, how do you transform that energy into energy that's in a useful form, a kind of chemical energy that can drive these building blocks to condense into long rana chains? I think we would all agree that that has not been solved. So

you've spoken to us a lot about the virtues of r and a is a sort of a triple threat. All these things it does in modern biology, but it's a little surprising to not hear about its more famous an dna. Is there something wrong with dna compared to or na for early life? So

that's actually a superinteresting question. We used to think that life definitely started with just arnay, because we were thinking about ribazims, arna, catalus, arnas, rolls an, modern cells.
