0:12:02 > 0:12:05- Hey, everybody, look what I've got.- What the...?
0:12:05 > 0:12:08- Professor, where on Earth did you find that?- Erm, nowhere.
0:12:08 > 0:12:10I just found it, you know?
0:12:16 > 0:12:18Hmm, a likely story.
0:12:18 > 0:12:21Wow! It's so beautiful.
0:12:21 > 0:12:26Yeah, it's all right, I suppose. Here, have a go of it if you like.
0:12:26 > 0:12:29Positions, everybody! We're going live.
0:12:29 > 0:12:32This is Brain Freeze!
0:12:32 > 0:12:35With Dr Knowles...
0:12:35 > 0:12:37Professor McCork...
0:12:37 > 0:12:39and...
0:12:39 > 0:12:40Colin the floor manager.
0:12:42 > 0:12:44Stand by!
0:12:52 > 0:12:54Hello and welcome to Brain Freeze.
0:12:54 > 0:12:55It's time for...
0:12:55 > 0:12:57Today's Big Question!
0:12:57 > 0:13:01Today we're asking, why did the dinosaurs become extinct?
0:13:01 > 0:13:05Oh, I love dinosaurs. They make me feel so young.
0:13:05 > 0:13:07Long before humans ever appeared,
0:13:07 > 0:13:12dinosaurs roamed the Earth for over 160 million years.
0:13:12 > 0:13:15In order to survive, they developed different characteristics
0:13:15 > 0:13:17to best suit the environment they lived in.
0:13:17 > 0:13:20Fierce teeth for hunting, long necks for feeding,
0:13:20 > 0:13:21tough armour for protection.
0:13:21 > 0:13:24Skinny legs for dancing, squinty eyes for lying,
0:13:24 > 0:13:26bonny bellies for tickling.
0:13:27 > 0:13:30Professor, what have I told you before about making up science?
0:13:30 > 0:13:33Erm, was it to stop making up science?
0:13:33 > 0:13:36Oh, sorry, Doctor.
0:13:36 > 0:13:38I think it's time for a short break.
0:13:40 > 0:13:41And we're clear!
0:13:41 > 0:13:43Well, how's the egg doing?
0:13:43 > 0:13:46Erm, I think there's something you two should see.
0:13:46 > 0:13:47THEY GASP
0:13:47 > 0:13:50Look! Something's hatching!
0:13:51 > 0:13:53BIRD SQUAWKS "COLIN"
0:13:53 > 0:13:56Ahhhh.
0:13:56 > 0:13:59- Oh! It said my name!- Ha!
0:13:59 > 0:14:02It thinks you're its mammy, that's brilliant.
0:14:02 > 0:14:05- Ouch!- Uh-oh, erm, guys...
0:14:06 > 0:14:08Here comes another one.
0:14:09 > 0:14:12McCork, what have you done?!
0:14:12 > 0:14:14Come on, let's get out of here.
0:14:14 > 0:14:16Oh, crumpets! Positions, everyone!
0:14:18 > 0:14:19Welcome back, everyone.
0:14:19 > 0:14:22I think it's time we got straight to the bottom of this one.
0:14:22 > 0:14:24Today's Big Answer!
0:14:24 > 0:14:28So, Dr Knowles, why did the dinosaurs become extinct?
0:14:28 > 0:14:29There are several theories,
0:14:29 > 0:14:33but most scientists agree that it was probably triggered by a large
0:14:33 > 0:14:37asteroid that struck the Earth about 65 million years ago.
0:14:38 > 0:14:40Those that survived the initial impact
0:14:40 > 0:14:43faced a dramatic change in the Earth's climate -
0:14:43 > 0:14:44an impact winter -
0:14:44 > 0:14:47which may have lasted for thousands of years.
0:14:47 > 0:14:49Most dinosaurs just weren't able to cope
0:14:49 > 0:14:52with such a rapid change in their environment.
0:14:52 > 0:14:56That's so sad, but what do you mean "most" dinosaurs?
0:14:56 > 0:14:59Well, numerous fossil findings have confirmed that a group of
0:14:59 > 0:15:02dinosaurs known as theropods actually had feathers.
0:15:02 > 0:15:05- Feathers? On a dinosaur, are you serious?- Yeah.
0:15:05 > 0:15:09Most scientist believed that during this time, certain smaller dinosaurs
0:15:09 > 0:15:12were evolving into early forms of the birds we see today.
0:15:12 > 0:15:15Well, it's good to know I'm not the only dinosaur left around the place.
0:15:15 > 0:15:17See you next time, folks.
0:15:19 > 0:15:21You know, Dr Knowles, you're probably right.
0:15:21 > 0:15:23I'd say I shouldn't have brought that egg in at all.
0:15:23 > 0:15:25Really? You reckon?
0:15:25 > 0:15:28Anyway, Colin seems to have the whole thing under control.
0:15:28 > 0:15:29Don't you, Colin?
0:15:29 > 0:15:31BIRDS SQUAWK "COLIN"
0:15:35 > 0:15:39- He's a natural.- Yeah. You look like you're in a zoo, Colin.
0:15:39 > 0:15:44Believe me, McCork, this place feels like a zoo every single day.
