Encore: The misfit mammal that defies biological conventions

We've got about two million specimens covering the whole of the animal kingdom, the whole of geological time, or biological time, I should say, the whole of the world.

Conversations
Encore: The misfit mammal that defies biological conventions

So, as you say, we've got a lot of Darwin specimens here.

Conversations
Encore: The misfit mammal that defies biological conventions

He was a student at Cambridge for a few years, and...

Conversations

ended up leaving his collections to the Cambridge Philosophical Society, which is one of the founding parts of our museum.

Conversations
Encore: The misfit mammal that defies biological conventions

We have, and we've got... What Darwin did when he came back from the Beagle is to partition off different groups of animals to different experts in those fields.

Conversations
Encore: The misfit mammal that defies biological conventions

And we ended up, or Cambridge ended up, with the fishes, which might not be the sexiest part of the Beagle collection, but...

Conversations
Encore: The misfit mammal that defies biological conventions

So we've got Darwin's Fishes from the Beagle.

Conversations
Encore: The misfit mammal that defies biological conventions

We've also got the finches that came back from the Beagle, which are probably the most famous thing to come off the Beagle because Darwin's finches, I'm doing air quotes around Darwin's finches here, are perhaps the best example of how evolution worked in Darwin's eyes.

Conversations
Encore: The misfit mammal that defies biological conventions

So these are...

Conversations
Encore: The misfit mammal that defies biological conventions

The Galapagos finches.

Conversations
Encore: The misfit mammal that defies biological conventions

A finch, it turns out, or one species of finch, flew from South America to the Galapagos Islands and there evolved into 14 different species with different beaks.

Conversations
Encore: The misfit mammal that defies biological conventions

Some beaks for big nut-cracking beaks for smashing seeds.

Conversations
Encore: The misfit mammal that defies biological conventions

Some really fine beaks for pecking flowers.

Conversations
Encore: The misfit mammal that defies biological conventions

And

Conversations
Encore: The misfit mammal that defies biological conventions

And Darwin used this as an example of adaptive radiation, to say this is how it evolved.

Conversations
Encore: The misfit mammal that defies biological conventions

But the reason I did air quotes is because our finches aren't actually collected by Darwin.

Conversations
Encore: The misfit mammal that defies biological conventions

They were collected by the captain Fitzroy and one of the crew, Fuller, who actually did a far better job than Darwin of labelling the specimens and where they came from.

Conversations
Encore: The misfit mammal that defies biological conventions

The first platypus specimen I saw was actually in the museum in which I now work in Cambridge as an undergraduate many years ago.

Conversations
Encore: The misfit mammal that defies biological conventions

And our course in zoology was essentially you were given one group of animals per week and we'd have a load of lectures about that group and then we'd go to the museum for practical sessions with the specimens.

Conversations
Encore: The misfit mammal that defies biological conventions

Absolutely.
