The Martin Lewis podcast is now twice weekly, helping you navigate our complex consumer world.

In one, I'll walk you through a big money saving topic step by step. Then in the new

question time, you set the agenda and ask whatever's on your mind. Within reason, the Martin

Lewis podcast, now twice weekly. Listen on BBC Sounds.

You're about to listen to a brand new episode of Curious Cases.

Shows are going to be released weekly, wherever you get your podcast.

But if you're in the UK, you can listen to the latest episodes first on BBC Sounds.

I'm Hannah Fry.

And I'm Dara O'Brien. And this is Curious Cases. The show will we take your quirkiest questions? Your crudious conundrums. And then we solve them. With the power of science.

I mean, do we always solve them? I mean, the hit rate's pretty low. But it is with science.

It is with science. Here's an interesting I did recently. I was, did something with the Natural History Museum, just in a kind of standing in the room while they're doing proper work, like whatever. For a new exhibit that's running at the moment, but space, right? Is there life in outer space? But as part of it, I was nudging them, and they went for this, that they'd have a speculative bit at the end, they were thinking of doing this, where they would basically say, well, what might life be like under different gravitational conditions and different stars? Exactly, in different plans what it might look like. So they kind of went, okay, what could be fairly safe to make a guess that an alien life might look like, right it's not going to be Chewbacca, right? You can't say that for sure. I'm fairly sure I can say. It's not all going to be what looks like a person in a suit. And so they have this kind of like, you know, nicely presented to kind of a vague sense of what these things might look like. And a lot of them look like paramecium. A lot of them look like, you know, very, very evolutionary, very kind of simple cell of life. Like, and you're kind of going, okay, grand, that makes sense. But the only really recognisable thing was a crap. A crab? A crab. Yeah, yeah, that'd be a crap. No, there'll definitely be a crap. The most evolutionary, stable possible. Seems to be like a very evolutionary friendly thing, a crap. You're low?

You're low. You're low. You're hard. You can walk sideways. Oh, look, no one's expecting that. That's the weird thing about it. No one is expecting that. Oi, where'd you go? No idea. I'm looking at you. I'm looking at you. I'm looking at you. I'm looking at you. I'm looking at staying your right. No, I'm now going left. Yeah.

Also, the crab eyes can move around. I mean, independent of the crab legs. I mean, we don't acclaim them enough. They're amazing. I think you're absolutely right. Which is why there's an excellent question about crab. Certainly is. Hello, we are Carston and Emily from Cornwall. and we're interested in the weird and wacky nature of evolution.

We read about carcinisation, which is when non-crack and Emily from Cornwall and we're interested in the weird and wacky nature of evolution.

We read about carcinisation, which is when non-crab organisms evolved to have crab-like bodies.

Why have so many different species evolved into crabs?

Does this mean that crabs are the ideal life form? And if so, could humans eventually become crabs? Okay, how cool do they sound? And also I really like the fact that there is implicit in this a sense of these two young women are going, will this happen in our life? I mean, what year are we talking? We're young and we're staring at our old future ahead of us but it it's part of it going to be a click-click-click-click.

Are we going to be castanetting with our claws, you know. 20-60. Yeah. Everything's craps. There's a meme about this. I don't know if you've seen this. No, I haven't. All the people on the internet have been making jokes about how eventually everything's going to involve into crabs. There was Monterey Bay Aquarium, for example,

one of the most prestigious and respected marine institutions on the planet.
