-Hey, everybody, look what I've got.
-Professor, where on Earth did you find that?
I just found it, you know?
Hmm, a likely story.
Wow! It's so beautiful.
Yeah, it's all right, I suppose. Here, have a go of it if you like.
Positions, everybody! We're going live.
This is Brain Freeze!
With Dr Knowles...
Colin the floor manager.
Hello and welcome to Brain Freeze.
It's time for...
Today's Big Question!
Today we're asking, why did the dinosaurs become extinct?
Oh, I love dinosaurs. They make me feel so young.
Long before humans ever appeared,
dinosaurs roamed the Earth for over 160 million years.
In order to survive, they developed different characteristics
to best suit the environment they lived in.
Fierce teeth for hunting, long necks for feeding,
tough armour for protection.
Skinny legs for dancing, squinty eyes for lying,
bonny bellies for tickling.
Professor, what have I told you before about making up science?
Erm, was it to stop making up science?
Oh, sorry, Doctor.
I think it's time for a short break.
And we're clear!
Well, how's the egg doing?
Erm, I think there's something you two should see.
Look! Something's hatching!
BIRD SQUAWKS "COLIN"
-Oh! It said my name!
It thinks you're its mammy, that's brilliant.
-Uh-oh, erm, guys...
Here comes another one.
McCork, what have you done?!
Come on, let's get out of here.
Oh, crumpets! Positions, everyone!
Welcome back, everyone.
I think it's time we got straight to the bottom of this one.
Today's Big Answer!
So, Dr Knowles, why did the dinosaurs become extinct?
There are several theories,
but most scientists agree that it was probably triggered by a large
asteroid that struck the Earth about 65 million years ago.
Those that survived the initial impact
faced a dramatic change in the Earth's climate -
an impact winter -
which may have lasted for thousands of years.
Most dinosaurs just weren't able to cope
with such a rapid change in their environment.
That's so sad, but what do you mean "most" dinosaurs?
Well, numerous fossil findings have confirmed that a group of
dinosaurs known as theropods actually had feathers.
-Feathers? On a dinosaur, are you serious?
Most scientist believed that during this time, certain smaller dinosaurs
were evolving into early forms of the birds we see today.
Well, it's good to know I'm not the only dinosaur left around the place.
See you next time, folks.
You know, Dr Knowles, you're probably right.
I'd say I shouldn't have brought that egg in at all.
Really? You reckon?
Anyway, Colin seems to have the whole thing under control.
Don't you, Colin?
BIRDS SQUAWK "COLIN"
-He's a natural.
-Yeah. You look like you're in a zoo, Colin.
Believe me, McCork, this place feels like a zoo every single day.
