Today we bring you a man who, 150 years ago, | 0:01:19 | 0:01:22 | |
changed the way we understand the entire world around us. | 0:01:22 | 0:01:25 | |
Yeah, if there was ever a Champions League of Geniuses, | 0:01:25 | 0:01:28 | |
this guy would qualify every season. | 0:01:28 | 0:01:30 | |
Ladies and gentlemen, we bring you the great, | 0:01:30 | 0:01:32 | |
the incredible, Charles Darwin! | 0:01:32 | 0:01:34 | |
Greetings, gentlemen! | 0:01:34 | 0:01:35 | |
Inspired by this man's sheer brilliance and genius, | 0:01:35 | 0:01:38 | |
we're going to be coming up with our own daring genius idea | 0:01:38 | 0:01:41 | |
later on in the show. | 0:01:41 | 0:01:43 | |
We'll be taking the plunge, going face-to-face | 0:01:43 | 0:01:46 | |
with one of the most perfectly evolved predators on the planet. | 0:01:46 | 0:01:49 | |
But first, let's find out a bit more about this revolutionary chap. | 0:01:50 | 0:01:54 | |
Charles Darwin was born in 1809. | 0:01:55 | 0:01:58 | |
From an early age, he was fascinated in the world around him. | 0:01:58 | 0:02:02 | |
He became a naturalist, someone who studies everything in nature. | 0:02:02 | 0:02:06 | |
He would gaze for hours at rocks, plants and flowers, | 0:02:06 | 0:02:10 | |
and loved collecting all kinds of living things. | 0:02:10 | 0:02:12 | |
From wiggly worms to feisty little critters like this. | 0:02:12 | 0:02:16 | |
DOM LAUGHS | 0:02:16 | 0:02:17 | |
Then, in 1831, Darwin went on a five-year voyage, | 0:02:17 | 0:02:21 | |
in a ship called the Beagle, to South America. | 0:02:21 | 0:02:25 | |
What he learnt on his travels and the years of research that followed | 0:02:25 | 0:02:28 | |
would lead him to come up with | 0:02:28 | 0:02:29 | |
one of the most important ideas there has ever been. | 0:02:29 | 0:02:32 | |
And the idea is STILL amazing now! | 0:02:32 | 0:02:35 | |
Darwin said that everything in nature | 0:02:35 | 0:02:37 | |
was connected in a kind of giant family tree, | 0:02:37 | 0:02:41 | |
and started from a single living organism | 0:02:41 | 0:02:44 | |
that lived millions of years ago. | 0:02:44 | 0:02:46 | |
His genius idea is known as the theory of evolution. | 0:02:46 | 0:02:50 | |
It's based on something he called "natural selection". | 0:02:50 | 0:02:54 | |
Different kinds or species of animal, insect, fish, bird, plant - | 0:02:54 | 0:02:59 | |
every living thing - would, over thousands of years, | 0:02:59 | 0:03:02 | |
adapt and slowly change, | 0:03:02 | 0:03:04 | |
until sometimes an entire new species would come into being. | 0:03:04 | 0:03:08 | |
Ah, good morning! | 0:03:08 | 0:03:10 | |
Evolution was a revolutionary idea | 0:03:10 | 0:03:13 | |
because, in Darwin's day, most Europeans believed | 0:03:13 | 0:03:16 | |
that EVERYTHING was created by God, as told in the Bible. | 0:03:16 | 0:03:19 | |
To start to find out how Darwin came up with his theory of evolution, | 0:03:19 | 0:03:23 | |
we've come here, to the magnificent Natural History Museum in London. | 0:03:23 | 0:03:28 | |
In here are some of the actual things he collected | 0:03:28 | 0:03:31 | |
on his travels and lots more besides. | 0:03:31 | 0:03:33 | |
This is the Tank Room. | 0:03:33 | 0:03:36 | |
And, to show us some of the amazing creatures in here, | 0:03:37 | 0:03:41 | |
it's Genius Helper Jon Ablett. | 0:03:41 | 0:03:43 | |
CHAINS RATTLE | 0:03:44 | 0:03:47 | |
-Lovely. -Urgh! | 0:03:47 | 0:03:48 | |
What is THAT?! | 0:03:48 | 0:03:50 | |
These are some of our fish specimens | 0:03:50 | 0:03:51 | |
that we keep in the Tank Room of the Natural History Museum. | 0:03:51 | 0:03:54 | |
-Oh, bleurgh! -It stinks! | 0:03:54 | 0:03:55 | |
And I just breathed in through me nose! | 0:03:55 | 0:03:57 | |
-DOM COUGHS -Is that like just pickling vinegar? | 0:03:57 | 0:04:00 | |
Yeah, well, we use alcohol and they should keep for hundreds of years. | 0:04:00 | 0:04:03 | |
But why do you preserve them? | 0:04:03 | 0:04:04 | |
Scientists from inside the museum and around the world | 0:04:04 | 0:04:07 | |
can come here and study them. | 0:04:07 | 0:04:08 | |
Are we...? Are we allowed? | 0:04:08 | 0:04:09 | |
You're not going to touch one of them. Don't do it! | 0:04:09 | 0:04:11 | |
Blargh! | 0:04:11 | 0:04:12 | |
It feels like...leather. | 0:04:12 | 0:04:14 | |
Let it swim away. Let it swim away. | 0:04:14 | 0:04:16 | |
Right, swim away. | 0:04:16 | 0:04:18 | |
DEEP VOICE: "All right? My name's Dave." | 0:04:18 | 0:04:20 | |
All right, Dave? | 0:04:20 | 0:04:21 | |
Argh...it's heavy! What is that? | 0:04:21 | 0:04:23 | |
It's me mother. THEY LAUGH | 0:04:23 | 0:04:25 | |
What's she doing in this tank? | 0:04:25 | 0:04:26 | |
-It's a monkfish? -It's a monkfish, yeah. | 0:04:26 | 0:04:28 | |
These are brilliant, but have you got anything | 0:04:28 | 0:04:30 | |
that Darwin brought back from his travels all those years ago? | 0:04:30 | 0:04:33 | |
Yeah, we've got lots of different specimens. Let's go. | 0:04:33 | 0:04:35 | |
This is Darwin's pet tortoise. | 0:04:37 | 0:04:39 | |
-This is actually... -This is it? -This is HIS pet tortoise? | 0:04:39 | 0:04:42 | |
And what about the octopus in this jar? | 0:04:42 | 0:04:44 | |
Pet octopus? It's not very cuddly, is it?! | 0:04:44 | 0:04:46 | |
It's one of the first things that he collected on his Beagle voyage. | 0:04:46 | 0:04:50 | |
Darwin wanted to know how the octopus | 0:04:50 | 0:04:52 | |
fitted into his theory of evolution. | 0:04:52 | 0:04:55 | |
Octopuses are part of a group of creatures called molluscs | 0:04:55 | 0:04:58 | |
that also includes squid, slugs and snails. | 0:04:58 | 0:05:02 | |
But how do we know that? | 0:05:02 | 0:05:04 | |
What we do is we look at the shared characteristics they had. | 0:05:04 | 0:05:07 | |
On a snail, for example, it's very easy to see they have a shell. | 0:05:07 | 0:05:10 | |
All right, fellas? | 0:05:10 | 0:05:11 | |
But squid and octopus are a bit more like a slug. | 0:05:11 | 0:05:13 | |
The shell has been reduced through evolution - | 0:05:13 | 0:05:15 | |
it's actually on the inside of the body. | 0:05:15 | 0:05:17 | |
So these have a shell inside them. | 0:05:17 | 0:05:19 | |
Look, it's part of your family. | 0:05:19 | 0:05:21 | |
-It's a bit older than you, though! -DOM CHUCKLES | 0:05:21 | 0:05:24 | |
Darwin was fascinated by the way different animals were related. | 0:05:24 | 0:05:28 | |
But there was one bizarre sea creature, | 0:05:28 | 0:05:30 | |
with over 1,000 species, that he was obsessed with. | 0:05:30 | 0:05:34 | |
To show us is Miranda Lowe, Curator of Crustacea. | 0:05:35 | 0:05:39 | |
These look like birds' claws. What are they? | 0:05:40 | 0:05:42 | |
These are actually barnacles. | 0:05:42 | 0:05:44 | |
-What exactly are barnacles? -They're creatures that live in the sea. | 0:05:44 | 0:05:47 | |
They're in the family crustacea, | 0:05:47 | 0:05:48 | |
which include shrimps, crabs, lobsters. | 0:05:48 | 0:05:51 | |
Darwin studied them obsessively for eight years. | 0:05:51 | 0:05:54 | |
Eight years?! | 0:05:54 | 0:05:56 | |
He studied them so much that his children | 0:05:56 | 0:05:58 | |
actually thought that everybody's dad did that. | 0:05:58 | 0:06:02 | |
So, when they went to visit their friends, | 0:06:02 | 0:06:04 | |
they would say, "Where does your father do barnacles?" | 0:06:04 | 0:06:06 | |
Yeah, "Where's your dad's barnacles?" | 0:06:06 | 0:06:08 | |
Why for so long? | 0:06:08 | 0:06:09 | |
He studied them for so long | 0:06:09 | 0:06:11 | |
because he wanted to accurately describe them or classify them. | 0:06:11 | 0:06:14 | |
And, from that, he found out there was one barnacle | 0:06:14 | 0:06:17 | |
that was the basis for all the other species. | 0:06:17 | 0:06:20 | |
So, if you trace back time far enough, | 0:06:20 | 0:06:23 | |
there would be one grandaddy of all barnacles | 0:06:23 | 0:06:26 | |
-and that's where it all started, right? -Absolutely. | 0:06:26 | 0:06:28 | |
That idea - of every living thing | 0:06:28 | 0:06:30 | |
being descended from a single ancestor - | 0:06:30 | 0:06:33 | |
was a key part of Darwin's theories. | 0:06:33 | 0:06:35 | |
And there's one interesting thing about barnacles. | 0:06:35 | 0:06:39 | |
When they're small, they secrete something similar to concrete, | 0:06:39 | 0:06:44 | |
which will attach them to a rock for the rest of their lives. | 0:06:44 | 0:06:48 | |
And, because of that, it's very difficult for them to reproduce. | 0:06:48 | 0:06:51 | |
Yeah, of course, cos you need to contact each other to reproduce. | 0:06:51 | 0:06:54 | |
So, if they're separate here and here, what happens? | 0:06:54 | 0:06:56 | |
They are known in the animal kingdom of having the largest willy | 0:06:56 | 0:07:00 | |
so that they can reproduce with other barnacles... | 0:07:00 | 0:07:03 | |
Hold on a minute, Miranda! | 0:07:03 | 0:07:04 | |
Are you saying that the barnacle...? | 0:07:04 | 0:07:06 | |
The reproductive organ came out of here | 0:07:06 | 0:07:08 | |
and travelled all the way round, to one round here and...? | 0:07:08 | 0:07:10 | |
It can. | 0:07:10 | 0:07:12 | |
Because they're cemented to a rock, so that's the only way to reproduce. | 0:07:12 | 0:07:16 | |
DOM, AS DAVID ATTENBOROUGH: And here we see the barnacle mating. | 0:07:17 | 0:07:21 | |
A lovely example of evolution there! | 0:07:21 | 0:07:23 | |
Barnacles evolved so they could mate whilst stuck to a rock. | 0:07:23 | 0:07:27 | |
In the same way, giraffes have evolved long necks | 0:07:27 | 0:07:30 | |
to reach food that other animals can't, | 0:07:30 | 0:07:33 | |
and some lizards have grown very long tongues to catch insects. | 0:07:33 | 0:07:37 | |
OK, so Darwin was onto something pretty big back then. | 0:07:38 | 0:07:42 | |
Yeah, because Darwin's evolutionary theories | 0:07:42 | 0:07:44 | |
weren't just about octopuses and barnacles. | 0:07:44 | 0:07:46 | |
Oh, no, no! | 0:07:46 | 0:07:48 | |
It was about every living thing on the planet, | 0:07:48 | 0:07:51 | |
including human beings. | 0:07:51 | 0:07:53 | |
This is the Grant Museum of Zoology in London. | 0:07:53 | 0:07:57 | |
Here there are tons of preserved animals and skeletons - | 0:07:57 | 0:08:00 | |
more examples of how different species | 0:08:00 | 0:08:02 | |
are connected through evolution. | 0:08:02 | 0:08:04 | |
Smile! | 0:08:04 | 0:08:05 | |
Show us your teeth. | 0:08:05 | 0:08:06 | |
That's it. Lovely. CAMERA CLICKS | 0:08:06 | 0:08:08 | |
Meet Professor Steve Jones. | 0:08:11 | 0:08:14 | |
He's an expert in biology | 0:08:14 | 0:08:15 | |
and knows all about how one species can evolve into another. | 0:08:15 | 0:08:20 | |
So, Steve, obviously Darwin's theories changed the way | 0:08:20 | 0:08:23 | |
that we look at animals, humans, the human race, biology. | 0:08:23 | 0:08:27 | |
But what did we think of animals beforehand? | 0:08:27 | 0:08:31 | |
I mean, if you look at this lion, for example. | 0:08:31 | 0:08:34 | |
Now, when you look at it, | 0:08:34 | 0:08:35 | |
that looks like a very big cat when you think about it, a domestic cat. | 0:08:35 | 0:08:38 | |
And, of course, it is. | 0:08:38 | 0:08:40 | |
There's evidence now that cats are related to lions. | 0:08:40 | 0:08:43 | |
And we know that dogs have evolved from wolves. | 0:08:43 | 0:08:46 | |
But these were radical new ideas in Darwin's time. | 0:08:46 | 0:08:49 | |
To people of that day, either God had done it | 0:08:49 | 0:08:52 | |
or, somehow, it just kind of happened. | 0:08:52 | 0:08:55 | |
It just was. | 0:08:55 | 0:08:56 | |
People interested in lions knew a lot about lions | 0:08:56 | 0:08:59 | |
but they didn't know anything about wolves. | 0:08:59 | 0:09:01 | |
And what Darwin did was to connect everything together. | 0:09:01 | 0:09:05 | |
And he connected them together with his genius idea, natural selection. | 0:09:05 | 0:09:10 | |
Natural selection, remember, is Darwin's way | 0:09:10 | 0:09:12 | |
of explaining how evolution can change one creature, | 0:09:12 | 0:09:16 | |
so much so that it becomes a whole new species. | 0:09:16 | 0:09:19 | |
Like this one, called the dugong. | 0:09:19 | 0:09:21 | |
Believe it or not, this used to be a completely different animal | 0:09:21 | 0:09:25 | |
that lived on land and even had arms and legs. | 0:09:25 | 0:09:29 | |
But, through evolution, it slowly lost them over millions of years. | 0:09:29 | 0:09:33 | |
And the evidence is these rather eccentric-looking bones here. | 0:09:33 | 0:09:37 | |
Oh, yeah. | 0:09:37 | 0:09:38 | |
And what that is is what we call the pelvis. | 0:09:38 | 0:09:40 | |
The part of your body which your legs are attached to. | 0:09:40 | 0:09:43 | |
But there's nothing attached to the pelvis here. | 0:09:43 | 0:09:46 | |
It's been reduced to almost nothing. | 0:09:46 | 0:09:47 | |
And you can see another example. | 0:09:47 | 0:09:49 | |
If you look at a living dugong, | 0:09:49 | 0:09:51 | |
it's got nice flippers, a bit like a seal. | 0:09:51 | 0:09:53 | |
But, if you look at the bones, that flipper is in fact a hand... | 0:09:53 | 0:09:56 | |
Wow, look! | 0:09:56 | 0:09:57 | |
..with one, two, three, four, five digits and a little tiny thumb. | 0:09:57 | 0:10:01 | |
Now in this glass case is a series of skulls | 0:10:01 | 0:10:03 | |
showing how human beings have evolved from apes. | 0:10:03 | 0:10:07 | |
And today there's lots of evidence that we are related to chimpanzees. | 0:10:07 | 0:10:12 | |
But, back in Darwin's time, this was a difficult idea to accept. | 0:10:13 | 0:10:18 | |
Why were people uncomfortable with the idea | 0:10:18 | 0:10:19 | |
that humans were related to apes? | 0:10:19 | 0:10:21 | |
I think it's because they seemed to think that this dragged them down, | 0:10:21 | 0:10:26 | |
this made them less human than they had thought they were. | 0:10:26 | 0:10:29 | |
But we have all kinds of things that these creatures simply don't have. | 0:10:29 | 0:10:33 | |
As far as we can tell, they're unique to us. | 0:10:33 | 0:10:35 | |
We have a sense of beauty, a sense of history, a sense of the future. | 0:10:35 | 0:10:38 | |
Some people have a sense of religion. | 0:10:38 | 0:10:40 | |
To me, you needed the theory of evolution | 0:10:40 | 0:10:43 | |
to make us feel truly human. | 0:10:43 | 0:10:45 | |
Darwin's theories were really controversial at the time | 0:10:45 | 0:10:48 | |
because they conflicted with religious views, | 0:10:48 | 0:10:51 | |
like those in the Bible about the creation of the world | 0:10:51 | 0:10:54 | |
and the creatures in it. | 0:10:54 | 0:10:55 | |
And his ideas can still cause controversy today | 0:10:55 | 0:10:58 | |
for the same reasons. | 0:10:58 | 0:10:59 | |
So I'm starting to understand Darwin's genius idea | 0:11:00 | 0:11:03 | |
and this process of natural selection, | 0:11:03 | 0:11:05 | |
but we could do with seeing it in action. | 0:11:05 | 0:11:07 | |
Yeah, if only Fran, our friendly scientist, was here to help. | 0:11:07 | 0:11:11 | |
Fran! | 0:11:11 | 0:11:12 | |
Hello! | 0:11:12 | 0:11:13 | |
'This is Fran.' | 0:11:13 | 0:11:15 | |
'She just loves experimenting...' | 0:11:15 | 0:11:17 | |
Wow! | 0:11:17 | 0:11:18 | |
'..to help explain the ideas of our geniuses.' | 0:11:18 | 0:11:20 | |
Argh! | 0:11:20 | 0:11:22 | |
'And she's sure to pop up just when you really need her.' | 0:11:22 | 0:11:25 | |
Fran, what on earth are you doing in there? | 0:11:25 | 0:11:27 | |
I'm testing my camouflage. | 0:11:27 | 0:11:28 | |
-So camouflage... You know camouflage, right? -Yeah, yeah. | 0:11:28 | 0:11:31 | |
Characteristics that a lot of animals use to try and blend in | 0:11:31 | 0:11:34 | |
with their background to hide from their predators. | 0:11:34 | 0:11:36 | |
What's this got to do with natural selection? | 0:11:36 | 0:11:38 | |
Well, I've got an experiment that involves camouflage | 0:11:38 | 0:11:41 | |
that's going to show us exactly how natural selection works. | 0:11:41 | 0:11:45 | |
Lots of animals have natural camouflage. | 0:11:45 | 0:11:48 | |
And, over years and years, nature "selects" the best kind. | 0:11:48 | 0:11:52 | |
Creatures with good camouflage are more likely to survive. | 0:11:52 | 0:11:56 | |
We're going to play a kind of experimental hide-and-seek | 0:11:56 | 0:11:59 | |
to show how this works. | 0:11:59 | 0:12:00 | |
Right then, Fran, what do you think? | 0:12:03 | 0:12:05 | |
-Well, you-you're camouflaged, sort of. -Yup. | 0:12:05 | 0:12:08 | |
-By the way, you look ridiculous. -I mean, look at that. -Stupid! | 0:12:08 | 0:12:11 | |
Imagine we're a species of woodland creature. | 0:12:11 | 0:12:14 | |
-Quite a timid woodland creature. -Oh, timid. | 0:12:14 | 0:12:16 | |
-We're scared of the Predator. -Oh. -Yeah. | 0:12:16 | 0:12:18 | |
-So meet the Predator. -The Predator? -The Predator? | 0:12:18 | 0:12:21 | |
Ooh, this is going to be nasty, isn't it? | 0:12:21 | 0:12:24 | |
All right, mate? Apparently, there's a predator turning up in a minute. | 0:12:24 | 0:12:28 | |
Be careful. | 0:12:28 | 0:12:29 | |
Where is it? Eh? | 0:12:29 | 0:12:32 | |
THEY LAUGH YOU'RE the Predator?! | 0:12:32 | 0:12:34 | |
Look - little fella, wearing an orange jumper! | 0:12:34 | 0:12:37 | |
-Brilliant, can't wait for this. -Easy. | 0:12:37 | 0:12:39 | |
Well, this Predator is going to hunt us. | 0:12:39 | 0:12:41 | |
So we're going to see who's selected the best camouflage. | 0:12:41 | 0:12:45 | |
'While we look for hiding places...' | 0:12:45 | 0:12:46 | |
One, two... | 0:12:46 | 0:12:48 | |
'..the Predator counts to 100. | 0:12:48 | 0:12:50 | |
'He's going to try to find us | 0:12:52 | 0:12:54 | |
'and splat us with orange paintball pellets.' | 0:12:54 | 0:12:56 | |
'Fran's camouflage hides her really well.' | 0:13:07 | 0:13:11 | |
He can't see me - it's brilliant! | 0:13:11 | 0:13:13 | |
'But pink camouflage can't hide you for long in these woods.' | 0:13:18 | 0:13:21 | |
He's seen me. | 0:13:25 | 0:13:26 | |
Agh! | 0:13:26 | 0:13:27 | |
Urgh... | 0:13:27 | 0:13:28 | |
'My yellow camouflage is better than pink in these surroundings. | 0:13:30 | 0:13:34 | |
'But it's only a matter of time...' | 0:13:34 | 0:13:35 | |
Spotted him. | 0:13:35 | 0:13:37 | |
Ah, yes. Now, Tom, you see, I know I was taking the mick earlier. | 0:13:37 | 0:13:40 | |
But, to be honest, I love orange. It's my favourite colour. | 0:13:40 | 0:13:43 | |
Get away...! Ooh! ARGH! | 0:13:43 | 0:13:44 | |
-Gentlemen, you've been splatted! -HE LAUGHS | 0:13:44 | 0:13:46 | |
What does that all mean? | 0:13:46 | 0:13:48 | |
This is natural selection in action. | 0:13:48 | 0:13:50 | |
So it means that, in our species, | 0:13:50 | 0:13:51 | |
animals with my colouring would be more likely to survive - | 0:13:51 | 0:13:55 | |
because I didn't get shot - to an age where we could reproduce. | 0:13:55 | 0:13:59 | |
This means that, over time, | 0:13:59 | 0:14:01 | |
our species would all have Fran's colouring. | 0:14:01 | 0:14:04 | |
We've seen how important camouflage is to survive in the wild. | 0:14:04 | 0:14:07 | |
So which creatures have the best camouflage? | 0:14:07 | 0:14:11 | |
It's the Genius Top Five. | 0:14:13 | 0:14:15 | |
At five, the polar bear. | 0:14:15 | 0:14:17 | |
That furry white coat is perfect for hunting in the snow. | 0:14:17 | 0:14:20 | |
Let's get out of here! | 0:14:20 | 0:14:22 | |
Four, the slipper sole. | 0:14:22 | 0:14:24 | |
A sandy-coloured flatfish | 0:14:24 | 0:14:25 | |
that blends in brilliantly with the sea bed. | 0:14:25 | 0:14:27 | |
Mwahahaha! | 0:14:27 | 0:14:29 | |
Three, the leopard. | 0:14:29 | 0:14:30 | |
Dark spots and a yellowy-brown coat | 0:14:30 | 0:14:32 | |
for hiding under the hot African sun. | 0:14:32 | 0:14:35 | |
Yum, yum, yum, yum. | 0:14:35 | 0:14:37 | |
Two, the walking leaf. | 0:14:37 | 0:14:39 | |
This isn't part of a tree, it's actually an insect. | 0:14:39 | 0:14:41 | |
That's a leaf, or I'm a monkey! | 0:14:41 | 0:14:43 | |
One, the chameleon. | 0:14:43 | 0:14:45 | |
A lizard that changes its colour depending on how it's feeling. | 0:14:45 | 0:14:49 | |
Greeny-brown is great camouflage in the jungle | 0:14:49 | 0:14:51 | |
but red means, "Danger! Keep your distance!" | 0:14:51 | 0:14:55 | |
You should be seeing red, mate! | 0:14:55 | 0:14:56 | |
So we're starting to understand Darwin's theory of evolution, | 0:14:58 | 0:15:01 | |
how everything in nature is connected and changes over time. | 0:15:01 | 0:15:05 | |
And, later on, we'll be coming face-to-face | 0:15:05 | 0:15:08 | |
with a perfectly-evolved predator. | 0:15:08 | 0:15:11 | |
THEY BOTH YELL | 0:15:11 | 0:15:12 | |
It's got the pole! | 0:15:12 | 0:15:14 | |
When Darwin got back from South America, | 0:15:14 | 0:15:16 | |
he continued his naturalist studies here in Britain. | 0:15:16 | 0:15:18 | |
Yeah, he settled down, had a family, got married | 0:15:18 | 0:15:21 | |
and lived HERE for 40 years, in this beautiful house. | 0:15:21 | 0:15:25 | |
This is Down House in Kent, | 0:15:25 | 0:15:27 | |
where Darwin worked and where he lived... | 0:15:27 | 0:15:30 | |
with his wife and ten children. | 0:15:30 | 0:15:32 | |
Yes, TEN! | 0:15:32 | 0:15:35 | |
Darwin's little 'uns used to like to play a trick on their dad. | 0:15:35 | 0:15:38 | |
Yeah. Now, Darwin was the kind of guy | 0:15:38 | 0:15:39 | |
that liked a fixed daily routine. | 0:15:39 | 0:15:42 | |
And, every single day, he would walk around this part of the garden | 0:15:42 | 0:15:45 | |
five times, which meant he would have walked exactly one mile. | 0:15:45 | 0:15:49 | |
He measured his walk by placing five stones at a certain point | 0:15:49 | 0:15:53 | |
and then kicking one away each time he went round. | 0:15:53 | 0:15:57 | |
His children, though, would hide in the undergrowth, | 0:15:57 | 0:15:59 | |
sneak out once he had gone by and replace the stone. | 0:15:59 | 0:16:03 | |
Naughty children! | 0:16:03 | 0:16:04 | |
But, when he was at home, | 0:16:04 | 0:16:06 | |
Darwin spent most of his time in this study. | 0:16:06 | 0:16:09 | |
It's here that he wrote down all his ground-breaking ideas. | 0:16:09 | 0:16:13 | |
And giving us access-all-areas is Annie Kemkaran-Smith, | 0:16:14 | 0:16:18 | |
Curator of Down House. | 0:16:18 | 0:16:20 | |
Annie, it's incredible being in this room. | 0:16:20 | 0:16:22 | |
But it's actually quite... small and modest, | 0:16:22 | 0:16:24 | |
considering the amount of AMAZING work that came out of here. | 0:16:24 | 0:16:27 | |
He spent an awful lot of time in this room. | 0:16:27 | 0:16:29 | |
He wrote all of his 19 books in this room, | 0:16:29 | 0:16:31 | |
including this one, On The Origin Of Species, | 0:16:31 | 0:16:34 | |
which was published in 1859. | 0:16:34 | 0:16:36 | |
-BOTH: -Can we? -Yes. | 0:16:36 | 0:16:38 | |
DOM CHUCKLES | 0:16:38 | 0:16:39 | |
-Don't touch it with your finger! -Argh! | 0:16:39 | 0:16:42 | |
DOM LAUGHS | 0:16:42 | 0:16:44 | |
"When on board HMS Beagle as a naturalist, | 0:16:44 | 0:16:47 | |
"I was much struck with certain facts in the distribution | 0:16:47 | 0:16:49 | |
"of the inhabitants of South America." | 0:16:49 | 0:16:51 | |
-That's enough for today. More tomorrow! -Lovely. | 0:16:51 | 0:16:54 | |
'On The Origin Of Species | 0:16:54 | 0:16:55 | |
'is Darwin's most famous book about evolution. | 0:16:55 | 0:16:58 | |
'But he delayed publishing it for 15 years.' | 0:16:58 | 0:17:02 | |
Annie, why have you taken us to a cupboard under the stairs? | 0:17:02 | 0:17:05 | |
This is possibly one of the most important cupboards in history, | 0:17:05 | 0:17:08 | |
because, in here, Darwin put his rough version of his book - | 0:17:08 | 0:17:12 | |
On The Origin Of Species - | 0:17:12 | 0:17:14 | |
and, in 1844, packaged it up, put it under the stairs, | 0:17:14 | 0:17:18 | |
with a note to his wife, Emma, saying, | 0:17:18 | 0:17:20 | |
"If I'm to die, you're to get this published," | 0:17:20 | 0:17:22 | |
because he realised how important it was. | 0:17:22 | 0:17:24 | |
What he had here in this package was the very beginnings | 0:17:24 | 0:17:28 | |
of questioning the story that the Bible set out. | 0:17:28 | 0:17:31 | |
He knew that people weren't going to be very happy about that. | 0:17:31 | 0:17:33 | |
So he needed to have absolute 100% evidence to back that up | 0:17:33 | 0:17:38 | |
before he put it in the public domain. | 0:17:38 | 0:17:40 | |
Darwin realised that his theories would only be accepted | 0:17:40 | 0:17:43 | |
if he could explain the relationship of everything in nature. | 0:17:43 | 0:17:48 | |
He had to show how even the really weird stuff fitted in. | 0:17:48 | 0:17:52 | |
Why, for instance, would a plant evolve to eat insects? | 0:17:52 | 0:17:56 | |
Like this one, the Venus fly trap. | 0:17:56 | 0:17:59 | |
Meet Rowan Blaik, Head Gardener at Down House. | 0:17:59 | 0:18:03 | |
He works here, in Darwin's original greenhouse. | 0:18:03 | 0:18:07 | |
Why was Darwin so interested in carnivorous plants? | 0:18:07 | 0:18:10 | |
What was he trying to discover about them? | 0:18:10 | 0:18:12 | |
He knew that carnivorous plants live in really poor soil | 0:18:12 | 0:18:15 | |
with very few nutrients, | 0:18:15 | 0:18:16 | |
and he wanted to show that they're just like other living plants - | 0:18:16 | 0:18:21 | |
they need nitrogen to survive. | 0:18:21 | 0:18:23 | |
But they're getting their nitrogen from the bugs that they catch. | 0:18:23 | 0:18:27 | |
Darwin tested lots of carnivorous plants | 0:18:27 | 0:18:29 | |
including this one, called the sundew. | 0:18:29 | 0:18:31 | |
We're going to do an experiment to find out | 0:18:31 | 0:18:33 | |
how the sundew is related to other plants | 0:18:33 | 0:18:36 | |
and why it evolved into a meat eater! | 0:18:36 | 0:18:38 | |
With the sundew, what Darwin did was he would feed them cheese, | 0:18:40 | 0:18:44 | |
and cooked meat, and toenail clippings. | 0:18:44 | 0:18:46 | |
Ah, right. Well, it just so happens | 0:18:46 | 0:18:48 | |
I've got my ham sandwich here from lunch. | 0:18:48 | 0:18:49 | |
-Can we feed the plant a bit of this ham? -Yeah, sure. | 0:18:49 | 0:18:52 | |
So we've got meat for our sundew plant. | 0:18:52 | 0:18:55 | |
That's got nitrogen. | 0:18:55 | 0:18:56 | |
And so have my nail clippings. | 0:18:56 | 0:18:58 | |
There we go. | 0:19:00 | 0:19:01 | |
And, believe it or not, something else Darwin tried with the sundew | 0:19:01 | 0:19:04 | |
was his own urine. | 0:19:04 | 0:19:06 | |
Yes, piddle is full of nitrogen! | 0:19:06 | 0:19:09 | |
Time for a tinkle. | 0:19:09 | 0:19:11 | |
Oh, I know. Do bogies have nitrogen? | 0:19:11 | 0:19:13 | |
-They do a bit, yeah. -Ahh! -Do they?! -Yeah. | 0:19:13 | 0:19:16 | |
It's all in the name of science. | 0:19:16 | 0:19:18 | |
Hold your wee in one hand. Hold my nails here. | 0:19:18 | 0:19:20 | |
Sorry, viewer, it's all in the name of science! | 0:19:20 | 0:19:23 | |
'Don't try this at home.' | 0:19:23 | 0:19:24 | |
Goodness' sake! | 0:19:24 | 0:19:25 | |
It's black! You've got black bogies! | 0:19:25 | 0:19:27 | |
I work down the mines. | 0:19:27 | 0:19:29 | |
Now to put the ham, | 0:19:29 | 0:19:31 | |
nail clippings, | 0:19:31 | 0:19:33 | |
bogey, | 0:19:33 | 0:19:34 | |
and piddle on the sundew and see if it tries to eat them. | 0:19:34 | 0:19:37 | |
To compare, we're also putting sugar on the plant | 0:19:37 | 0:19:40 | |
because that doesn't contain nitrogen. | 0:19:40 | 0:19:43 | |
While we wait for the sundew plant to do its stuff... | 0:19:43 | 0:19:46 | |
..it's time for the Not So Genius Idea! | 0:19:46 | 0:19:50 | |
Darwin's great ideas came from hours of thinking, | 0:19:50 | 0:19:53 | |
often on long walks on his own. | 0:19:53 | 0:19:55 | |
But thinking can be dangerous. | 0:19:55 | 0:19:57 | |
One time, he was so preoccupied in his thoughts, | 0:19:57 | 0:20:00 | |
he walked right off the edge of a wall and fell. | 0:20:00 | 0:20:03 | |
Fortunately, the drop wasn't very far and he wasn't seriously hurt. | 0:20:03 | 0:20:06 | |
But he was thinking while falling! Later, he wrote... | 0:20:06 | 0:20:11 | |
"The number of thoughts which passed through my mind | 0:20:11 | 0:20:14 | |
"during this very short but sudden and wholly unexpected fall, | 0:20:14 | 0:20:18 | |
"was astonishing." | 0:20:18 | 0:20:20 | |
-SPLAT! -Urgh! | 0:20:20 | 0:20:22 | |
24 hours later, has the sundew plant experiment worked? | 0:20:22 | 0:20:25 | |
Well, yes. Mostly. | 0:20:25 | 0:20:27 | |
Unsurprisingly, it didn't fancy nitrogen-free sugar or the nails. | 0:20:27 | 0:20:31 | |
But, on this special camera, | 0:20:31 | 0:20:33 | |
we can see how the sundew's hairs wrap greedily around my bogey | 0:20:33 | 0:20:37 | |
and slurp up the nitrogen from Dick's wee. | 0:20:37 | 0:20:41 | |
So, Darwin's experiment shows why the sundew evolved | 0:20:41 | 0:20:44 | |
into a carnivorous species and how it's related to other plant life. | 0:20:44 | 0:20:49 | |
-Pumpkins. -It was great to recreate one of Darwin's experiments. | 0:20:51 | 0:20:54 | |
And I think it's given us some ideas for our own Genius Challenge! | 0:20:54 | 0:20:57 | |
It really has. When Darwin was off on his voyage, | 0:20:57 | 0:20:59 | |
he got up close and personal | 0:20:59 | 0:21:00 | |
with all of the wildlife he was documenting. | 0:21:00 | 0:21:02 | |
Yeah, I think we need to find an animal that's hungry, more ravenous, | 0:21:02 | 0:21:05 | |
-top of the food chain! -I know it! | 0:21:05 | 0:21:07 | |
-Sharks! -Yes! | 0:21:07 | 0:21:08 | |
But where will we find sharks? Where do we go? | 0:21:08 | 0:21:10 | |
-Do we go to Sydney, Australia? -No. | 0:21:10 | 0:21:11 | |
-Do we go to the Caribbean? -No. I've got somewhere better in mind. | 0:21:11 | 0:21:14 | |
-Hm? -Cheshire. -Cheshire... | 0:21:14 | 0:21:16 | |
-THINKS: -'I love Cheshire.' | 0:21:16 | 0:21:18 | |
Our Genius Idea, to go diving with sharks. | 0:21:18 | 0:21:21 | |
These terrifying fish are one of the most perfect examples | 0:21:21 | 0:21:24 | |
of evolution in the animal kingdom. | 0:21:24 | 0:21:26 | |
Our challenge - to come face-to-face with these mighty marine predators, | 0:21:26 | 0:21:30 | |
to find out for ourselves why they're top of the food chain! | 0:21:30 | 0:21:33 | |
Our problem - can we pluck up the courage to get in the water | 0:21:33 | 0:21:37 | |
with these fearsome fish?! | 0:21:37 | 0:21:38 | |
BUUUURP! | 0:21:38 | 0:21:40 | |
Right. Sharks! | 0:21:44 | 0:21:45 | |
-Come on. -OK, I'm coming. | 0:21:48 | 0:21:49 | |
-No. -Come on. -All right, yes. | 0:21:51 | 0:21:53 | |
Helping us with our challenge is marine biology dude, | 0:21:54 | 0:21:57 | |
and heavy rock fan, the Blowfish. | 0:21:57 | 0:21:59 | |
His favourite shark is, of course, the guitar shark. | 0:21:59 | 0:22:03 | |
That's just one of eight different kinds of shark | 0:22:05 | 0:22:07 | |
here at the Blue Planet Aquarium in Cheshire. | 0:22:07 | 0:22:11 | |
But before we get in the water with these fellas, | 0:22:11 | 0:22:13 | |
Blowfish is going to show us some other examples of perfect evolution, | 0:22:13 | 0:22:18 | |
creatures that brilliantly adapted to their environment | 0:22:18 | 0:22:20 | |
millions of years ago. | 0:22:20 | 0:22:22 | |
First up is the spider crab. | 0:22:24 | 0:22:26 | |
This is a crustacean and, believe it or not, | 0:22:26 | 0:22:28 | |
these guys are related to the gooseneck barnacle. | 0:22:28 | 0:22:32 | |
Ah! Darwin's favourite little pet. | 0:22:32 | 0:22:34 | |
That's the one! | 0:22:34 | 0:22:35 | |
Next, a reptile that's as old as the dinosaurs. | 0:22:35 | 0:22:39 | |
These guys are cayman. They belong to the alligator family. | 0:22:39 | 0:22:43 | |
They look like dinosaurs, right? | 0:22:43 | 0:22:45 | |
Well, essentially, they ARE dinosaurs. | 0:22:45 | 0:22:47 | |
They're not as big as they used to be | 0:22:47 | 0:22:49 | |
but they have not changed in any other way. | 0:22:49 | 0:22:52 | |
And they share their pond with this turtle. | 0:22:52 | 0:22:55 | |
-You cheeky so and so! -Look at that! | 0:22:55 | 0:22:57 | |
Believe it or not, long, long ago, snakes used to have legs. | 0:22:57 | 0:23:02 | |
This reticulated python is perfectly evolved for slithering. | 0:23:02 | 0:23:06 | |
WHY...?! DICK LAUGHS | 0:23:06 | 0:23:08 | |
Why is it after me?! | 0:23:08 | 0:23:09 | |
But, just like the dugong we saw earlier, it once had legs, | 0:23:11 | 0:23:14 | |
but lost them through evolution. | 0:23:14 | 0:23:16 | |
And so to the kings of perfect evolution. | 0:23:17 | 0:23:21 | |
SHARKS! | 0:23:21 | 0:23:23 | |
HE GASPS What the...?! | 0:23:23 | 0:23:25 | |
Sharks have been around for an incredible 420 million years - | 0:23:25 | 0:23:30 | |
that's long before the dinosaurs even arrived. | 0:23:30 | 0:23:33 | |
So they've spent all that time on the planet being honed by evolution. | 0:23:33 | 0:23:37 | |
But very, very quickly, they hit a winning formula. | 0:23:37 | 0:23:40 | |
The thing that really changed the game was those jaws - | 0:23:40 | 0:23:43 | |
when a shark opens its mouth, | 0:23:43 | 0:23:45 | |
special muscles on either side of its jaw lock into place, | 0:23:45 | 0:23:49 | |
throwing the mouth forward, up and down. | 0:23:49 | 0:23:52 | |
Just about the size of your head. | 0:23:52 | 0:23:54 | |
Time to see those jaws in action. | 0:23:56 | 0:23:59 | |
That fish is surrounded. It's got no chance. | 0:24:02 | 0:24:04 | |
Oh, my goodness! Look at the size of that. | 0:24:04 | 0:24:07 | |
Oh, look. Look, look, look, look. | 0:24:10 | 0:24:13 | |
-Ah! -Oh! | 0:24:13 | 0:24:14 | |
It's got the pole. | 0:24:14 | 0:24:16 | |
-Ah! -Ho! | 0:24:16 | 0:24:18 | |
Look at the teeth! | 0:24:18 | 0:24:20 | |
-It's ripped the bit of wood! -Look! | 0:24:21 | 0:24:23 | |
Like a saw! | 0:24:23 | 0:24:24 | |
We've seen that they like their food | 0:24:25 | 0:24:27 | |
and that they're very feisty predators. | 0:24:27 | 0:24:30 | |
And now... | 0:24:30 | 0:24:31 | |
we're going to swim with them. | 0:24:31 | 0:24:33 | |
This is it. The moment of truth. | 0:24:35 | 0:24:38 | |
I am absolutely terrified. | 0:24:38 | 0:24:41 | |
For the first time on this show, | 0:24:41 | 0:24:44 | |
I'm looking forward to doing a challenge. | 0:24:44 | 0:24:46 | |
I'm not that scared. | 0:24:46 | 0:24:48 | |
And look... | 0:24:48 | 0:24:49 | |
HE is in my boat for once. | 0:24:49 | 0:24:53 | |
Mm. Yeah. It's absolutely awful. | 0:24:53 | 0:24:55 | |
'But there's no turning back now.' | 0:24:55 | 0:24:57 | |
There he goes, look at him. He's gone! | 0:25:02 | 0:25:04 | |
Underwater, it's a whole new world... | 0:25:06 | 0:25:08 | |
Oh, no, my turn. All right. | 0:25:12 | 0:25:14 | |
-BLOWFISH: -See you on the other side, Dom. | 0:25:14 | 0:25:17 | |
Oh, man... | 0:25:17 | 0:25:18 | |
Down on the bottom, we look out for our first shark. | 0:25:28 | 0:25:31 | |
Here it is - | 0:25:35 | 0:25:36 | |
a massive sand tiger shark! | 0:25:36 | 0:25:38 | |
It looks terrifying. | 0:25:40 | 0:25:43 | |
And it's not just sharks swimming around our heads. | 0:25:43 | 0:25:46 | |
That is a deadly stingray. | 0:25:46 | 0:25:48 | |
We're surrounded! | 0:25:49 | 0:25:51 | |
But, after a few minutes down here, | 0:25:55 | 0:25:57 | |
you realise that the sharks aren't really interested in us. | 0:25:57 | 0:26:01 | |
Knowing that, I finally begin to relax | 0:26:02 | 0:26:05 | |
and admire all these fantastic creatures. | 0:26:05 | 0:26:08 | |
All of them the result of millions of years of evolution. | 0:26:08 | 0:26:12 | |
And, soon, we forget about the danger altogether. | 0:26:12 | 0:26:15 | |
But, when our air runs low, it's time to come back to the surface. | 0:26:19 | 0:26:22 | |
-How was that, Dom? -Absolutely brilliant! | 0:26:26 | 0:26:29 | |
Really, it was. | 0:26:29 | 0:26:31 | |
It was like being in someone else's universe. | 0:26:31 | 0:26:34 | |
Here he comes. | 0:26:34 | 0:26:35 | |
DOM LAUGHS | 0:26:38 | 0:26:40 | |
Wasn't that AMAZING, eh?! | 0:26:40 | 0:26:44 | |
-I'm almost speechless. -Incredible! -Like walking into a different world. | 0:26:44 | 0:26:47 | |
And they didn't care. | 0:26:47 | 0:26:49 | |
And there's us being really stressed before and it was actually possibly | 0:26:49 | 0:26:52 | |
-one of the most peaceful things you could ever do. -Yeah. | 0:26:52 | 0:26:56 | |
Like... Oh! | 0:26:56 | 0:26:57 | |
'What a journey this has been! | 0:26:57 | 0:26:59 | |
'We've seen pickled monsters and live snakes...' | 0:26:59 | 0:27:02 | |
Why is after me?! | 0:27:02 | 0:27:03 | |
'..and creatures Darwin brought back from his travels.' | 0:27:03 | 0:27:06 | |
'We've learned how Darwin's theory of evolution | 0:27:06 | 0:27:09 | |
'explains how every living thing on the planet has evolved...' | 0:27:09 | 0:27:12 | |
'..how humans came from apes, how barnacles have babies... | 0:27:12 | 0:27:16 | |
Clever old chap, really! | 0:27:16 | 0:27:18 | |
'..but how some, like sharks, | 0:27:18 | 0:27:21 | |
'got everything just right a long, long time ago...' | 0:27:21 | 0:27:24 | |
Boys, you've just been in the water with 420 million years of evolution! | 0:27:24 | 0:27:28 | |
-THEY LAUGH -Thank you, Charles Darwin. | 0:27:28 | 0:27:31 | |
Yeah. I think you're an Absolute Genius! | 0:27:31 | 0:27:33 | |
Jolly kind of you to say so. | 0:27:33 | 0:27:35 | |
Argh! | 0:27:40 | 0:27:41 | |
Wargh! | 0:27:41 | 0:27:43 | |
It smacked me in the face! | 0:27:43 | 0:27:44 | |
-Dom's... -Oh, no! | 0:27:44 | 0:27:45 | |
THEY LAUGH | 0:27:45 | 0:27:47 | |
What are you doing?! | 0:27:47 | 0:27:49 | |
-THEY LAUGH -Let me get it straight! | 0:27:49 | 0:27:52 | |
Oh! | 0:27:52 | 0:27:53 | |
Oh, what's all that?! What's all the black stuff?! | 0:27:53 | 0:27:55 | |
-Ha-hey! -WHY...?! | 0:27:55 | 0:27:58 | |
