In Our Time · Seashells · 30 Jul 2026 podcast

We've used them as decoration, currency, musical instruments. voice-verified

But shells aren't just beautiful objects washed up on our beaches. voice-verified

Many belong to one of the most diverse groups of the animal kingdom, growing remarkable shapes, patterns and structures which tell us about the Earth's oceans – past, present and future. voice-verified

With me to discuss seashells are Suzanne Williams, merit researcher at the Natural History Museum, Liz Harper, professor of evolutionary malacology in the Department of Earth Sciences and fellow at Gonville and Caius College, University of Cambridge, and Helen Scales, marine biologist and author. voice-verified

Helen, I'm going to come to you first. voice-verified

The word seashells is not really a scientific term, is it? voice-verified

So what are we talking about when we say seashells? voice-verified

So how have we humans used shells throughout history? voice-verified

Liz Harper, let's get back to the mollusks themselves. voice-verified

How and why did they start to evolve these shells? voice-verified

So what actually is a shell physically? voice-verified

What makes it up? voice-verified

And how do you develop one if you're a mollusk? voice-verified

Just to be clear, they process the calcium and the carbon together... voice-verified

and then introduce the organics. voice-verified

And we can see the organic layer on top. voice-verified

Suzanne Williams, can you tell us about the differences between the different classes of mollusks and their respective shells? voice-verified

We'll talk about the ditons later on because they really are fascinating. voice-verified

But tell us also about the function of colour. voice-verified

Colour and mollusks is a fascinating subject. voice-verified
