MONKEYS CHATTER

0:00:480:00:51

Today we bring you a man who, 150 years ago,

0:01:190:01:22

changed the way we understand the entire world around us.

0:01:220:01:25

Yeah, if there was ever a Champions League of Geniuses,

0:01:250:01:28

this guy would qualify every season.

0:01:280:01:30

Ladies and gentlemen, we bring you the great,

0:01:300:01:32

the incredible, Charles Darwin!

0:01:320:01:34

Greetings, gentlemen!

0:01:340:01:35

Inspired by this man's sheer brilliance and genius,

0:01:350:01:38

we're going to be coming up with our own daring genius idea

0:01:380:01:41

later on in the show.

0:01:410:01:43

We'll be taking the plunge, going face-to-face

0:01:430:01:46

with one of the most perfectly evolved predators on the planet.

0:01:460:01:49

But first, let's find out a bit more about this revolutionary chap.

0:01:500:01:54

Charles Darwin was born in 1809.

0:01:550:01:58

From an early age, he was fascinated in the world around him.

0:01:580:02:02

He became a naturalist, someone who studies everything in nature.

0:02:020:02:06

He would gaze for hours at rocks, plants and flowers,

0:02:060:02:10

and loved collecting all kinds of living things.

0:02:100:02:12

From wiggly worms to feisty little critters like this.

0:02:120:02:16

DOM LAUGHS

0:02:160:02:17

Then, in 1831, Darwin went on a five-year voyage,

0:02:170:02:21

in a ship called the Beagle, to South America.

0:02:210:02:25

What he learnt on his travels and the years of research that followed

0:02:250:02:28

would lead him to come up with

0:02:280:02:29

one of the most important ideas there has ever been.

0:02:290:02:32

And the idea is STILL amazing now!

0:02:320:02:35

Darwin said that everything in nature

0:02:350:02:37

was connected in a kind of giant family tree,

0:02:370:02:41

and started from a single living organism

0:02:410:02:44

that lived millions of years ago.

0:02:440:02:46

His genius idea is known as the theory of evolution.

0:02:460:02:50

It's based on something he called "natural selection".

0:02:500:02:54

Different kinds or species of animal, insect, fish, bird, plant -

0:02:540:02:59

every living thing - would, over thousands of years,

0:02:590:03:02

adapt and slowly change,

0:03:020:03:04

until sometimes an entire new species would come into being.

0:03:040:03:08

Ah, good morning!

0:03:080:03:10

Evolution was a revolutionary idea

0:03:100:03:13

because, in Darwin's day, most Europeans believed

0:03:130:03:16

that EVERYTHING was created by God, as told in the Bible.

0:03:160:03:19

To start to find out how Darwin came up with his theory of evolution,

0:03:190:03:23

we've come here, to the magnificent Natural History Museum in London.

0:03:230:03:28

In here are some of the actual things he collected

0:03:280:03:31

on his travels and lots more besides.

0:03:310:03:33

This is the Tank Room.

0:03:330:03:36

And, to show us some of the amazing creatures in here,

0:03:370:03:41

it's Genius Helper Jon Ablett.

0:03:410:03:43

CHAINS RATTLE

0:03:440:03:47

-Lovely.

-Urgh!

0:03:470:03:48

What is THAT?!

0:03:480:03:50

These are some of our fish specimens

0:03:500:03:51

that we keep in the Tank Room of the Natural History Museum.

0:03:510:03:54

-Oh, bleurgh!

-It stinks!

0:03:540:03:55

And I just breathed in through me nose!

0:03:550:03:57

-DOM COUGHS

-Is that like just pickling vinegar?

0:03:570:04:00

Yeah, well, we use alcohol and they should keep for hundreds of years.

0:04:000:04:03

But why do you preserve them?

0:04:030:04:04

Scientists from inside the museum and around the world

0:04:040:04:07

can come here and study them.

0:04:070:04:08

Are we...? Are we allowed?

0:04:080:04:09

You're not going to touch one of them. Don't do it!

0:04:090:04:11

Blargh!

0:04:110:04:12

It feels like...leather.

0:04:120:04:14

Let it swim away. Let it swim away.

0:04:140:04:16

Right, swim away.

0:04:160:04:18

DEEP VOICE: "All right? My name's Dave."

0:04:180:04:20

All right, Dave?

0:04:200:04:21

Argh...it's heavy! What is that?

0:04:210:04:23

It's me mother. THEY LAUGH

0:04:230:04:25

What's she doing in this tank?

0:04:250:04:26

-It's a monkfish?

-It's a monkfish, yeah.

0:04:260:04:28

These are brilliant, but have you got anything

0:04:280:04:30

that Darwin brought back from his travels all those years ago?

0:04:300:04:33

Yeah, we've got lots of different specimens. Let's go.

0:04:330:04:35

This is Darwin's pet tortoise.

0:04:370:04:39

-This is actually...

-This is it?

-This is HIS pet tortoise?

0:04:390:04:42

And what about the octopus in this jar?

0:04:420:04:44

Pet octopus? It's not very cuddly, is it?!

0:04:440:04:46

It's one of the first things that he collected on his Beagle voyage.

0:04:460:04:50

Darwin wanted to know how the octopus

0:04:500:04:52

fitted into his theory of evolution.

0:04:520:04:55

Octopuses are part of a group of creatures called molluscs

0:04:550:04:58

that also includes squid, slugs and snails.

0:04:580:05:02

But how do we know that?

0:05:020:05:04

What we do is we look at the shared characteristics they had.

0:05:040:05:07

On a snail, for example, it's very easy to see they have a shell.

0:05:070:05:10

All right, fellas?

0:05:100:05:11

But squid and octopus are a bit more like a slug.

0:05:110:05:13

The shell has been reduced through evolution -

0:05:130:05:15

it's actually on the inside of the body.

0:05:150:05:17

So these have a shell inside them.

0:05:170:05:19

Look, it's part of your family.

0:05:190:05:21

-It's a bit older than you, though!

-DOM CHUCKLES

0:05:210:05:24

Darwin was fascinated by the way different animals were related.

0:05:240:05:28

But there was one bizarre sea creature,

0:05:280:05:30

with over 1,000 species, that he was obsessed with.

0:05:300:05:34

To show us is Miranda Lowe, Curator of Crustacea.

0:05:350:05:39

These look like birds' claws. What are they?

0:05:400:05:42

These are actually barnacles.

0:05:420:05:44

-What exactly are barnacles?

-They're creatures that live in the sea.

0:05:440:05:47

They're in the family crustacea,

0:05:470:05:48

which include shrimps, crabs, lobsters.

0:05:480:05:51

Darwin studied them obsessively for eight years.

0:05:510:05:54

Eight years?!

0:05:540:05:56

He studied them so much that his children

0:05:560:05:58

actually thought that everybody's dad did that.

0:05:580:06:02

So, when they went to visit their friends,

0:06:020:06:04

they would say, "Where does your father do barnacles?"

0:06:040:06:06

Yeah, "Where's your dad's barnacles?"

0:06:060:06:08

Why for so long?

0:06:080:06:09

He studied them for so long

0:06:090:06:11

because he wanted to accurately describe them or classify them.

0:06:110:06:14

And, from that, he found out there was one barnacle

0:06:140:06:17

that was the basis for all the other species.

0:06:170:06:20

So, if you trace back time far enough,

0:06:200:06:23

there would be one grandaddy of all barnacles

0:06:230:06:26

-and that's where it all started, right?

-Absolutely.

0:06:260:06:28

That idea - of every living thing

0:06:280:06:30

being descended from a single ancestor -

0:06:300:06:33

was a key part of Darwin's theories.

0:06:330:06:35

And there's one interesting thing about barnacles.

0:06:350:06:39

When they're small, they secrete something similar to concrete,

0:06:390:06:44

which will attach them to a rock for the rest of their lives.

0:06:440:06:48

And, because of that, it's very difficult for them to reproduce.

0:06:480:06:51

Yeah, of course, cos you need to contact each other to reproduce.

0:06:510:06:54

So, if they're separate here and here, what happens?

0:06:540:06:56

They are known in the animal kingdom of having the largest willy

0:06:560:07:00

so that they can reproduce with other barnacles...

0:07:000:07:03

Hold on a minute, Miranda!

0:07:030:07:04

Are you saying that the barnacle...?

0:07:040:07:06

The reproductive organ came out of here

0:07:060:07:08

and travelled all the way round, to one round here and...?

0:07:080:07:10

It can.

0:07:100:07:12

Because they're cemented to a rock, so that's the only way to reproduce.

0:07:120:07:16

DOM, AS DAVID ATTENBOROUGH: And here we see the barnacle mating.

0:07:170:07:21

A lovely example of evolution there!

0:07:210:07:23

Barnacles evolved so they could mate whilst stuck to a rock.

0:07:230:07:27

In the same way, giraffes have evolved long necks

0:07:270:07:30

to reach food that other animals can't,

0:07:300:07:33

and some lizards have grown very long tongues to catch insects.

0:07:330:07:37

OK, so Darwin was onto something pretty big back then.

0:07:380:07:42

Yeah, because Darwin's evolutionary theories

0:07:420:07:44

weren't just about octopuses and barnacles.

0:07:440:07:46

Oh, no, no!

0:07:460:07:48

It was about every living thing on the planet,

0:07:480:07:51

including human beings.

0:07:510:07:53

This is the Grant Museum of Zoology in London.

0:07:530:07:57

Here there are tons of preserved animals and skeletons -

0:07:570:08:00

more examples of how different species

0:08:000:08:02

are connected through evolution.

0:08:020:08:04

Smile!

0:08:040:08:05

Show us your teeth.

0:08:050:08:06

That's it. Lovely. CAMERA CLICKS

0:08:060:08:08

Meet Professor Steve Jones.

0:08:110:08:14

He's an expert in biology

0:08:140:08:15

and knows all about how one species can evolve into another.

0:08:150:08:20

So, Steve, obviously Darwin's theories changed the way

0:08:200:08:23

that we look at animals, humans, the human race, biology.

0:08:230:08:27

But what did we think of animals beforehand?

0:08:270:08:31

I mean, if you look at this lion, for example.

0:08:310:08:34

Now, when you look at it,

0:08:340:08:35

that looks like a very big cat when you think about it, a domestic cat.

0:08:350:08:38

And, of course, it is.

0:08:380:08:40

There's evidence now that cats are related to lions.

0:08:400:08:43

And we know that dogs have evolved from wolves.

0:08:430:08:46

But these were radical new ideas in Darwin's time.

0:08:460:08:49

To people of that day, either God had done it

0:08:490:08:52

or, somehow, it just kind of happened.

0:08:520:08:55

It just was.

0:08:550:08:56

People interested in lions knew a lot about lions

0:08:560:08:59

but they didn't know anything about wolves.

0:08:590:09:01

And what Darwin did was to connect everything together.

0:09:010:09:05

And he connected them together with his genius idea, natural selection.

0:09:050:09:10

Natural selection, remember, is Darwin's way

0:09:100:09:12

of explaining how evolution can change one creature,

0:09:120:09:16

so much so that it becomes a whole new species.

0:09:160:09:19

Like this one, called the dugong.

0:09:190:09:21

Believe it or not, this used to be a completely different animal

0:09:210:09:25

that lived on land and even had arms and legs.

0:09:250:09:29

But, through evolution, it slowly lost them over millions of years.

0:09:290:09:33

And the evidence is these rather eccentric-looking bones here.

0:09:330:09:37

Oh, yeah.

0:09:370:09:38

And what that is is what we call the pelvis.

0:09:380:09:40

The part of your body which your legs are attached to.

0:09:400:09:43

But there's nothing attached to the pelvis here.

0:09:430:09:46

It's been reduced to almost nothing.

0:09:460:09:47

And you can see another example.

0:09:470:09:49

If you look at a living dugong,

0:09:490:09:51

it's got nice flippers, a bit like a seal.

0:09:510:09:53

But, if you look at the bones, that flipper is in fact a hand...

0:09:530:09:56

Wow, look!

0:09:560:09:57

..with one, two, three, four, five digits and a little tiny thumb.

0:09:570:10:01

Now in this glass case is a series of skulls

0:10:010:10:03

showing how human beings have evolved from apes.

0:10:030:10:07

And today there's lots of evidence that we are related to chimpanzees.

0:10:070:10:12

But, back in Darwin's time, this was a difficult idea to accept.

0:10:130:10:18

Why were people uncomfortable with the idea

0:10:180:10:19

that humans were related to apes?

0:10:190:10:21

I think it's because they seemed to think that this dragged them down,

0:10:210:10:26

this made them less human than they had thought they were.

0:10:260:10:29

But we have all kinds of things that these creatures simply don't have.

0:10:290:10:33

As far as we can tell, they're unique to us.

0:10:330:10:35

We have a sense of beauty, a sense of history, a sense of the future.

0:10:350:10:38

Some people have a sense of religion.

0:10:380:10:40

To me, you needed the theory of evolution

0:10:400:10:43

to make us feel truly human.

0:10:430:10:45

Darwin's theories were really controversial at the time

0:10:450:10:48

because they conflicted with religious views,

0:10:480:10:51

like those in the Bible about the creation of the world

0:10:510:10:54

and the creatures in it.

0:10:540:10:55

And his ideas can still cause controversy today

0:10:550:10:58

for the same reasons.

0:10:580:10:59

So I'm starting to understand Darwin's genius idea

0:11:000:11:03

and this process of natural selection,

0:11:030:11:05

but we could do with seeing it in action.

0:11:050:11:07

Yeah, if only Fran, our friendly scientist, was here to help.

0:11:070:11:11

Fran!

0:11:110:11:12

Hello!

0:11:120:11:13

'This is Fran.'

0:11:130:11:15

'She just loves experimenting...'

0:11:150:11:17

Wow!

0:11:170:11:18

'..to help explain the ideas of our geniuses.'

0:11:180:11:20

Argh!

0:11:200:11:22

'And she's sure to pop up just when you really need her.'

0:11:220:11:25

Fran, what on earth are you doing in there?

0:11:250:11:27

I'm testing my camouflage.

0:11:270:11:28

-So camouflage... You know camouflage, right?

-Yeah, yeah.

0:11:280:11:31

Characteristics that a lot of animals use to try and blend in

0:11:310:11:34

with their background to hide from their predators.

0:11:340:11:36

What's this got to do with natural selection?

0:11:360:11:38

Well, I've got an experiment that involves camouflage

0:11:380:11:41

that's going to show us exactly how natural selection works.

0:11:410:11:45

Lots of animals have natural camouflage.

0:11:450:11:48

And, over years and years, nature "selects" the best kind.

0:11:480:11:52

Creatures with good camouflage are more likely to survive.

0:11:520:11:56

We're going to play a kind of experimental hide-and-seek

0:11:560:11:59

to show how this works.

0:11:590:12:00

Right then, Fran, what do you think?

0:12:030:12:05

-Well, you-you're camouflaged, sort of.

-Yup.

0:12:050:12:08

-By the way, you look ridiculous.

-I mean, look at that.

-Stupid!

0:12:080:12:11

Imagine we're a species of woodland creature.

0:12:110:12:14

-Quite a timid woodland creature.

-Oh, timid.

0:12:140:12:16

-We're scared of the Predator.

-Oh.

-Yeah.

0:12:160:12:18

-So meet the Predator.

-The Predator?

-The Predator?

0:12:180:12:21

Ooh, this is going to be nasty, isn't it?

0:12:210:12:24

All right, mate? Apparently, there's a predator turning up in a minute.

0:12:240:12:28

Be careful.

0:12:280:12:29

Where is it? Eh?

0:12:290:12:32

THEY LAUGH YOU'RE the Predator?!

0:12:320:12:34

Look - little fella, wearing an orange jumper!

0:12:340:12:37

-Brilliant, can't wait for this.

-Easy.

0:12:370:12:39

Well, this Predator is going to hunt us.

0:12:390:12:41

So we're going to see who's selected the best camouflage.

0:12:410:12:45

'While we look for hiding places...'

0:12:450:12:46

One, two...

0:12:460:12:48

'..the Predator counts to 100.

0:12:480:12:50

'He's going to try to find us

0:12:520:12:54

'and splat us with orange paintball pellets.'

0:12:540:12:56

'Fran's camouflage hides her really well.'

0:13:070:13:11

He can't see me - it's brilliant!

0:13:110:13:13

'But pink camouflage can't hide you for long in these woods.'

0:13:180:13:21

He's seen me.

0:13:250:13:26

Agh!

0:13:260:13:27

Urgh...

0:13:270:13:28

'My yellow camouflage is better than pink in these surroundings.

0:13:300:13:34

'But it's only a matter of time...'

0:13:340:13:35

Spotted him.

0:13:350:13:37

Ah, yes. Now, Tom, you see, I know I was taking the mick earlier.

0:13:370:13:40

But, to be honest, I love orange. It's my favourite colour.

0:13:400:13:43

Get away...! Ooh! ARGH!

0:13:430:13:44

-Gentlemen, you've been splatted!

-HE LAUGHS

0:13:440:13:46

What does that all mean?

0:13:460:13:48

This is natural selection in action.

0:13:480:13:50

So it means that, in our species,

0:13:500:13:51

animals with my colouring would be more likely to survive -

0:13:510:13:55

because I didn't get shot - to an age where we could reproduce.

0:13:550:13:59

This means that, over time,

0:13:590:14:01

our species would all have Fran's colouring.

0:14:010:14:04

We've seen how important camouflage is to survive in the wild.

0:14:040:14:07

So which creatures have the best camouflage?

0:14:070:14:11

It's the Genius Top Five.

0:14:130:14:15

At five, the polar bear.

0:14:150:14:17

That furry white coat is perfect for hunting in the snow.

0:14:170:14:20

Let's get out of here!

0:14:200:14:22

Four, the slipper sole.

0:14:220:14:24

A sandy-coloured flatfish

0:14:240:14:25

that blends in brilliantly with the sea bed.

0:14:250:14:27

Mwahahaha!

0:14:270:14:29

Three, the leopard.

0:14:290:14:30

Dark spots and a yellowy-brown coat

0:14:300:14:32

for hiding under the hot African sun.

0:14:320:14:35

Yum, yum, yum, yum.

0:14:350:14:37

Two, the walking leaf.

0:14:370:14:39

This isn't part of a tree, it's actually an insect.

0:14:390:14:41

That's a leaf, or I'm a monkey!

0:14:410:14:43

One, the chameleon.

0:14:430:14:45

A lizard that changes its colour depending on how it's feeling.

0:14:450:14:49

Greeny-brown is great camouflage in the jungle

0:14:490:14:51

but red means, "Danger! Keep your distance!"

0:14:510:14:55

You should be seeing red, mate!

0:14:550:14:56

So we're starting to understand Darwin's theory of evolution,

0:14:580:15:01

how everything in nature is connected and changes over time.

0:15:010:15:05

And, later on, we'll be coming face-to-face

0:15:050:15:08

with a perfectly-evolved predator.

0:15:080:15:11

THEY BOTH YELL

0:15:110:15:12

It's got the pole!

0:15:120:15:14

When Darwin got back from South America,

0:15:140:15:16

he continued his naturalist studies here in Britain.

0:15:160:15:18

Yeah, he settled down, had a family, got married

0:15:180:15:21

and lived HERE for 40 years, in this beautiful house.

0:15:210:15:25

This is Down House in Kent,

0:15:250:15:27

where Darwin worked and where he lived...

0:15:270:15:30

with his wife and ten children.

0:15:300:15:32

Yes, TEN!

0:15:320:15:35

Darwin's little 'uns used to like to play a trick on their dad.

0:15:350:15:38

Yeah. Now, Darwin was the kind of guy

0:15:380:15:39

that liked a fixed daily routine.

0:15:390:15:42

And, every single day, he would walk around this part of the garden

0:15:420:15:45

five times, which meant he would have walked exactly one mile.

0:15:450:15:49

He measured his walk by placing five stones at a certain point

0:15:490:15:53

and then kicking one away each time he went round.

0:15:530:15:57

His children, though, would hide in the undergrowth,

0:15:570:15:59

sneak out once he had gone by and replace the stone.

0:15:590:16:03

Naughty children!

0:16:030:16:04

But, when he was at home,

0:16:040:16:06

Darwin spent most of his time in this study.

0:16:060:16:09

It's here that he wrote down all his ground-breaking ideas.

0:16:090:16:13

And giving us access-all-areas is Annie Kemkaran-Smith,

0:16:140:16:18

Curator of Down House.

0:16:180:16:20

Annie, it's incredible being in this room.

0:16:200:16:22

But it's actually quite... small and modest,

0:16:220:16:24

considering the amount of AMAZING work that came out of here.

0:16:240:16:27

He spent an awful lot of time in this room.

0:16:270:16:29

He wrote all of his 19 books in this room,

0:16:290:16:31

including this one, On The Origin Of Species,

0:16:310:16:34

which was published in 1859.

0:16:340:16:36

-BOTH:

-Can we?

-Yes.

0:16:360:16:38

DOM CHUCKLES

0:16:380:16:39

-Don't touch it with your finger!

-Argh!

0:16:390:16:42

DOM LAUGHS

0:16:420:16:44

"When on board HMS Beagle as a naturalist,

0:16:440:16:47

"I was much struck with certain facts in the distribution

0:16:470:16:49

"of the inhabitants of South America."

0:16:490:16:51

-That's enough for today. More tomorrow!

-Lovely.

0:16:510:16:54

'On The Origin Of Species

0:16:540:16:55

'is Darwin's most famous book about evolution.

0:16:550:16:58

'But he delayed publishing it for 15 years.'

0:16:580:17:02

Annie, why have you taken us to a cupboard under the stairs?

0:17:020:17:05

This is possibly one of the most important cupboards in history,

0:17:050:17:08

because, in here, Darwin put his rough version of his book -

0:17:080:17:12

On The Origin Of Species -

0:17:120:17:14

and, in 1844, packaged it up, put it under the stairs,

0:17:140:17:18

with a note to his wife, Emma, saying,

0:17:180:17:20

"If I'm to die, you're to get this published,"

0:17:200:17:22

because he realised how important it was.

0:17:220:17:24

What he had here in this package was the very beginnings

0:17:240:17:28

of questioning the story that the Bible set out.

0:17:280:17:31

He knew that people weren't going to be very happy about that.

0:17:310:17:33

So he needed to have absolute 100% evidence to back that up

0:17:330:17:38

before he put it in the public domain.

0:17:380:17:40

Darwin realised that his theories would only be accepted

0:17:400:17:43

if he could explain the relationship of everything in nature.

0:17:430:17:48

He had to show how even the really weird stuff fitted in.

0:17:480:17:52

Why, for instance, would a plant evolve to eat insects?

0:17:520:17:56

Like this one, the Venus fly trap.

0:17:560:17:59

Meet Rowan Blaik, Head Gardener at Down House.

0:17:590:18:03

He works here, in Darwin's original greenhouse.

0:18:030:18:07

Why was Darwin so interested in carnivorous plants?

0:18:070:18:10

What was he trying to discover about them?

0:18:100:18:12

He knew that carnivorous plants live in really poor soil

0:18:120:18:15

with very few nutrients,

0:18:150:18:16

and he wanted to show that they're just like other living plants -

0:18:160:18:21

they need nitrogen to survive.

0:18:210:18:23

But they're getting their nitrogen from the bugs that they catch.

0:18:230:18:27

Darwin tested lots of carnivorous plants

0:18:270:18:29

including this one, called the sundew.

0:18:290:18:31

We're going to do an experiment to find out

0:18:310:18:33

how the sundew is related to other plants

0:18:330:18:36

and why it evolved into a meat eater!

0:18:360:18:38

With the sundew, what Darwin did was he would feed them cheese,

0:18:400:18:44

and cooked meat, and toenail clippings.

0:18:440:18:46

Ah, right. Well, it just so happens

0:18:460:18:48

I've got my ham sandwich here from lunch.

0:18:480:18:49

-Can we feed the plant a bit of this ham?

-Yeah, sure.

0:18:490:18:52

So we've got meat for our sundew plant.

0:18:520:18:55

That's got nitrogen.

0:18:550:18:56

And so have my nail clippings.

0:18:560:18:58

There we go.

0:19:000:19:01

And, believe it or not, something else Darwin tried with the sundew

0:19:010:19:04

was his own urine.

0:19:040:19:06

Yes, piddle is full of nitrogen!

0:19:060:19:09

Time for a tinkle.

0:19:090:19:11

Oh, I know. Do bogies have nitrogen?

0:19:110:19:13

-They do a bit, yeah.

-Ahh!

-Do they?!

-Yeah.

0:19:130:19:16

It's all in the name of science.

0:19:160:19:18

Hold your wee in one hand. Hold my nails here.

0:19:180:19:20

Sorry, viewer, it's all in the name of science!

0:19:200:19:23

'Don't try this at home.'

0:19:230:19:24

Goodness' sake!

0:19:240:19:25

It's black! You've got black bogies!

0:19:250:19:27

I work down the mines.

0:19:270:19:29

Now to put the ham,

0:19:290:19:31

nail clippings,

0:19:310:19:33

bogey,

0:19:330:19:34

and piddle on the sundew and see if it tries to eat them.

0:19:340:19:37

To compare, we're also putting sugar on the plant

0:19:370:19:40

because that doesn't contain nitrogen.

0:19:400:19:43

While we wait for the sundew plant to do its stuff...

0:19:430:19:46

..it's time for the Not So Genius Idea!

0:19:460:19:50

Darwin's great ideas came from hours of thinking,

0:19:500:19:53

often on long walks on his own.

0:19:530:19:55

But thinking can be dangerous.

0:19:550:19:57

One time, he was so preoccupied in his thoughts,

0:19:570:20:00

he walked right off the edge of a wall and fell.

0:20:000:20:03

Fortunately, the drop wasn't very far and he wasn't seriously hurt.

0:20:030:20:06

But he was thinking while falling! Later, he wrote...

0:20:060:20:11

"The number of thoughts which passed through my mind

0:20:110:20:14

"during this very short but sudden and wholly unexpected fall,

0:20:140:20:18

"was astonishing."

0:20:180:20:20

-SPLAT!

-Urgh!

0:20:200:20:22

24 hours later, has the sundew plant experiment worked?

0:20:220:20:25

Well, yes. Mostly.

0:20:250:20:27

Unsurprisingly, it didn't fancy nitrogen-free sugar or the nails.

0:20:270:20:31

But, on this special camera,

0:20:310:20:33

we can see how the sundew's hairs wrap greedily around my bogey

0:20:330:20:37

and slurp up the nitrogen from Dick's wee.

0:20:370:20:41

So, Darwin's experiment shows why the sundew evolved

0:20:410:20:44

into a carnivorous species and how it's related to other plant life.

0:20:440:20:49

-Pumpkins.

-It was great to recreate one of Darwin's experiments.

0:20:510:20:54

And I think it's given us some ideas for our own Genius Challenge!

0:20:540:20:57

It really has. When Darwin was off on his voyage,

0:20:570:20:59

he got up close and personal

0:20:590:21:00

with all of the wildlife he was documenting.

0:21:000:21:02

Yeah, I think we need to find an animal that's hungry, more ravenous,

0:21:020:21:05

-top of the food chain!

-I know it!

0:21:050:21:07

-Sharks!

-Yes!

0:21:070:21:08

But where will we find sharks? Where do we go?

0:21:080:21:10

-Do we go to Sydney, Australia?

-No.

0:21:100:21:11

-Do we go to the Caribbean?

-No. I've got somewhere better in mind.

0:21:110:21:14

-Hm?

-Cheshire.

-Cheshire...

0:21:140:21:16

-THINKS:

-'I love Cheshire.'

0:21:160:21:18

Our Genius Idea, to go diving with sharks.

0:21:180:21:21

These terrifying fish are one of the most perfect examples

0:21:210:21:24

of evolution in the animal kingdom.

0:21:240:21:26

Our challenge - to come face-to-face with these mighty marine predators,

0:21:260:21:30

to find out for ourselves why they're top of the food chain!

0:21:300:21:33

Our problem - can we pluck up the courage to get in the water

0:21:330:21:37

with these fearsome fish?!

0:21:370:21:38

BUUUURP!

0:21:380:21:40

Right. Sharks!

0:21:440:21:45

-Come on.

-OK, I'm coming.

0:21:480:21:49

-No.

-Come on.

-All right, yes.

0:21:510:21:53

Helping us with our challenge is marine biology dude,

0:21:540:21:57

and heavy rock fan, the Blowfish.

0:21:570:21:59

His favourite shark is, of course, the guitar shark.

0:21:590:22:03

That's just one of eight different kinds of shark

0:22:050:22:07

here at the Blue Planet Aquarium in Cheshire.

0:22:070:22:11

But before we get in the water with these fellas,

0:22:110:22:13

Blowfish is going to show us some other examples of perfect evolution,

0:22:130:22:18

creatures that brilliantly adapted to their environment

0:22:180:22:20

millions of years ago.

0:22:200:22:22

First up is the spider crab.

0:22:240:22:26

This is a crustacean and, believe it or not,

0:22:260:22:28

these guys are related to the gooseneck barnacle.

0:22:280:22:32

Ah! Darwin's favourite little pet.

0:22:320:22:34

That's the one!

0:22:340:22:35

Next, a reptile that's as old as the dinosaurs.

0:22:350:22:39

These guys are cayman. They belong to the alligator family.

0:22:390:22:43

They look like dinosaurs, right?

0:22:430:22:45

Well, essentially, they ARE dinosaurs.

0:22:450:22:47

They're not as big as they used to be

0:22:470:22:49

but they have not changed in any other way.

0:22:490:22:52

And they share their pond with this turtle.

0:22:520:22:55

-You cheeky so and so!

-Look at that!

0:22:550:22:57

Believe it or not, long, long ago, snakes used to have legs.

0:22:570:23:02

This reticulated python is perfectly evolved for slithering.

0:23:020:23:06

WHY...?! DICK LAUGHS

0:23:060:23:08

Why is it after me?!

0:23:080:23:09

But, just like the dugong we saw earlier, it once had legs,

0:23:110:23:14

but lost them through evolution.

0:23:140:23:16

And so to the kings of perfect evolution.

0:23:170:23:21

SHARKS!

0:23:210:23:23

HE GASPS What the...?!

0:23:230:23:25

Sharks have been around for an incredible 420 million years -

0:23:250:23:30

that's long before the dinosaurs even arrived.

0:23:300:23:33

So they've spent all that time on the planet being honed by evolution.

0:23:330:23:37

But very, very quickly, they hit a winning formula.

0:23:370:23:40

The thing that really changed the game was those jaws -

0:23:400:23:43

when a shark opens its mouth,

0:23:430:23:45

special muscles on either side of its jaw lock into place,

0:23:450:23:49

throwing the mouth forward, up and down.

0:23:490:23:52

Just about the size of your head.

0:23:520:23:54

Time to see those jaws in action.

0:23:560:23:59

That fish is surrounded. It's got no chance.

0:24:020:24:04

Oh, my goodness! Look at the size of that.

0:24:040:24:07

Oh, look. Look, look, look, look.

0:24:100:24:13

-Ah!

-Oh!

0:24:130:24:14

It's got the pole.

0:24:140:24:16

-Ah!

-Ho!

0:24:160:24:18

Look at the teeth!

0:24:180:24:20

-It's ripped the bit of wood!

-Look!

0:24:210:24:23

Like a saw!

0:24:230:24:24

We've seen that they like their food

0:24:250:24:27

and that they're very feisty predators.

0:24:270:24:30

And now...

0:24:300:24:31

we're going to swim with them.

0:24:310:24:33

This is it. The moment of truth.

0:24:350:24:38

I am absolutely terrified.

0:24:380:24:41

For the first time on this show,

0:24:410:24:44

I'm looking forward to doing a challenge.

0:24:440:24:46

I'm not that scared.

0:24:460:24:48

And look...

0:24:480:24:49

HE is in my boat for once.

0:24:490:24:53

Mm. Yeah. It's absolutely awful.

0:24:530:24:55

'But there's no turning back now.'

0:24:550:24:57

There he goes, look at him. He's gone!

0:25:020:25:04

Underwater, it's a whole new world...

0:25:060:25:08

Oh, no, my turn. All right.

0:25:120:25:14

-BLOWFISH:

-See you on the other side, Dom.

0:25:140:25:17

Oh, man...

0:25:170:25:18

Down on the bottom, we look out for our first shark.

0:25:280:25:31

Here it is -

0:25:350:25:36

a massive sand tiger shark!

0:25:360:25:38

It looks terrifying.

0:25:400:25:43

And it's not just sharks swimming around our heads.

0:25:430:25:46

That is a deadly stingray.

0:25:460:25:48

We're surrounded!

0:25:490:25:51

But, after a few minutes down here,

0:25:550:25:57

you realise that the sharks aren't really interested in us.

0:25:570:26:01

Knowing that, I finally begin to relax

0:26:020:26:05

and admire all these fantastic creatures.

0:26:050:26:08

All of them the result of millions of years of evolution.

0:26:080:26:12

And, soon, we forget about the danger altogether.

0:26:120:26:15

But, when our air runs low, it's time to come back to the surface.

0:26:190:26:22

-How was that, Dom?

-Absolutely brilliant!

0:26:260:26:29

Really, it was.

0:26:290:26:31

It was like being in someone else's universe.

0:26:400:26:44

-I'm almost speechless.

-Incredible!

-Like walking into a different world.

0:26:440:26:47

And they didn't care.

0:26:470:26:49

And there's us being really stressed before and it was actually possibly

0:26:490:26:52

0:27:210:27:24

Boys, you've just been in the water with 420 million years of evolution!

0:27:240:27:28

-THEY LAUGH

-Thank you, Charles Darwin.

0:27:280:27:31

Jolly kind of you to say so.

0:27:330:27:35

Argh!
