:05:04
	What the hell is it?
:05:06
	Could be a rock or some sort of fossil.
:05:08
	We picked it up in the Landsat satellite.
:05:10
	First we thought it was a cap deposit,
but the resolution is definitely solid.
:05:14
	How deep in the ice is it?
:05:15
	- Four, maybe five meters.
- What do we do about it?
:05:18
	I talked to the NASA research station
at Rundell Peak.
:05:21
	They'll take it until it melts,
and then decide what to do with it.
:05:24
	All right. Dig it up.
:05:30
	Language is a signaling system that uses
sounds to convey thoughts and emotions.
:05:34
	What makes humans unique
is our ability to introduce into language...
:05:38
	thoughts about the past,
present, or future...
:05:42
	at any point in time and space.
:05:44
	He'll call you back.
:05:49
	Not all language is based on sound.
:05:53
	We communicate in other ways...
:05:55
	that are much less overt
than the spoken word.
:05:58
	So do animals.
:06:00
	The only difference between them and us
can be summarized in one word: Novelty.
:06:05
	When an animal gives a warning
that danger is imminent...
:06:08
	it uses a series
of fairly predictable calls or signals...
:06:13
	that animals of its kind have used before.
:06:15
	This is decidedly not the case with humans.
:06:17
	Oxford English Dictionary
lists 615,000 words...
:06:21
	in the English language.
That's 3,000 more than five years ago...
:06:25
	and thousands less
than a few years from now.
:06:28
	On the other hand...
:06:30
	there's little or no novelty
in animal language.
:06:33
	Tragically, English cows
make the same sounds as French cows.
:06:47
	- Julian.
- Sam.
:06:49
	Listen. Bachman called.
He wants to see you right away.
:06:52
	- Why?
- I don't know.
:06:59
	Did he sound like there was a problem?
