0:35

of the week from the

0:38

Naked Scientists. Hello

0:44

and welcome to Question of the Week

0:47

this week Where answering this question sent

0:49

in by The Smith Fattier, she asks

0:51

why do languages evolve completely differently between

0:54

countries, even when they directly border each

0:56

other? Why do they have such different

0:58

dialects? Good. Question Satya and

1:00

to answer it. We'd enlisted the

1:02

help of offer and British linguist

1:05

David Crystal. Languages are different because

1:07

people are different. As

1:09

soon as one group of people move

1:11

away from another or or separated from

1:14

another by a barrier like a mountain

1:16

range, a river, then in a short

1:18

time they'll begin to speak in a

1:20

different way. They'll. Have new

1:22

words to reflect the new surroundings.

1:25

Their accent will change. It doesn't

1:27

take long. When people

1:29

from England move to America

1:32

in the seventeenth century, within

1:34

a few decades, British visitors

1:36

were remarking on an American

1:38

twine and all the new

1:40

words to do with the

1:42

American Indians or local wildlife.

1:45

You know, words like wigwam

1:47

and moccasin and skunk. Over

1:49

time, these differences increase and

1:51

eventually they're so noticeable that

1:53

we call them different dialects.

1:56

But at least with dialects, the people

1:58

understand each other. Over hundreds

2:00

maybe thousands of years the

2:02

differences become so great of

2:04

the speakers no longer understand

2:06

each other and then we

2:09

call them different languages. It's

2:11

all a matter of identity. A

2:14

community can show it's identity and

2:16

all kinds of ways searches how

2:18

they dress, but speech is the

2:20

easiest way to show that you

2:23

belong to a particular community. And

2:26

today, there are over six

2:28

thousand languages in the world,

2:30

And within that six thousand

2:32

there are in an uncountable

2:34

number of dialects. Remember, each

2:36

community is proud of it's

2:38

language or dialect. And

2:40

we should all be proud of this

2:43

diversity. Each language is a unique vision

2:45

of the world and of what it

2:47

means to be human. The. Bad

2:49

news is at this a language

2:52

disappearing in the world every three

2:54

months or so. The

2:56

good news is that organizations

2:58

like The Foundation for Endangered Languages

3:00

in the Uk are trying

3:02

to do something about it. For.

3:07

And. Next

3:10

week we answering this question sent in from

3:12

this that he and he asked has

3:14

anyone ever wondered when or why human started

3:16

eating sex education or we just copying

3:18

until cities were created and we lived

3:20

in isolated ring? How did we survive through

3:23

the transition from instinct to learning. And

3:25
