00:00:00,000 --> 00:00:03,610
Did you guys know that chickens
are made out of magic?

2
00:00:03,798 --> 00:00:05,398
(Music)

3
00:00:06,968 --> 00:00:07,856
Hey guys!

4
00:00:07,856 --> 00:00:09,906
So, is a Mercedes-Benz
like a chicken

5
00:00:09,906 --> 00:00:12,550
or is a chicken like a Mercades-Benz?

6
00:00:12,699 --> 00:00:13,796
Confused?

7
00:00:13,796 --> 00:00:14,912
Watch this.

8
00:00:15,162 --> 00:00:16,117
(Music)

9
00:00:23,572 --> 00:00:25,612
Its a new Mercedes-Benz ad

10
00:00:25,622 --> 00:00:28,542
which features a new stabilization system

11
00:00:28,542 --> 00:00:30,708
as advanced as a chicken's head.

12
00:00:30,718 --> 00:00:34,681
These chickens are demonstrating
their vestibulo-ocular reflex

13
00:00:34,681 --> 00:00:36,563
It's the ability that chickens use

14
00:00:36,563 --> 00:00:39,408
to stabilize their vision
while their body moves.

15
00:00:39,963 --> 00:00:41,333
Allow me to demonstrate.

16
00:00:41,333 --> 00:00:42,663
Stare at this eye

17
00:00:42,663 --> 00:00:44,804
while moving your head around in circles

18
00:00:44,804 --> 00:00:46,315
like a crazy person.

19
00:00:46,337 --> 00:00:47,502
What did you notice?

20
00:00:47,552 --> 00:00:49,454
While your head moves every which way,

21
00:00:49,454 --> 00:00:52,346
your eyes stayed
in relatively the same position.

22
00:00:52,407 --> 00:00:54,483
This is how we stabilize our eyes

23
00:00:54,483 --> 00:00:56,478
in order to process an image.

24
00:00:56,548 --> 00:00:58,423
Light shines through our pupil

25
00:00:58,423 --> 00:01:00,798
into the retina in the back of our eye,

26
00:01:00,798 --> 00:01:02,808
creating a retinal image.

27
00:01:02,988 --> 00:01:04,943
If our eyes move too quickly,

28
00:01:04,943 --> 00:01:06,940
we do not give ourself
enough time

29
00:01:06,940 --> 00:01:08,695
to process the retinal image,

30
00:01:08,755 --> 00:01:10,905
therefore, giving us blurry vision.

31
00:01:10,955 --> 00:01:12,479
We stabilize our vision

32
00:01:12,479 --> 00:01:14,522
through maintaining our eye position.

33
00:01:14,522 --> 00:01:16,715
and chickens stabilize their vision

34
00:01:16,715 --> 00:01:19,148
through maintaining their head position.

35
00:01:19,148 --> 00:01:22,010
Chickens don't have the same
ocular motor control as us.

36
00:01:22,114 --> 00:01:26,111
So, they have evolved the muscles
in their neck and their head

37
00:01:26,179 --> 00:01:28,118
to stabilize what they see.

38
00:01:28,178 --> 00:01:30,572
Not only do birds have stabilized heads,

39
00:01:30,572 --> 00:01:33,645
but other animals do too, like cats.

40
00:01:33,687 --> 00:01:35,167
It just doesn't look as cool

41
00:01:35,167 --> 00:01:36,382
When you move them around

42
00:01:36,382 --> 00:01:38,593
because chickens have that long neck!

43
00:01:38,593 --> 00:01:41,197
Allright, well, I'll see
you, hairy mammals, tomorrow.

44
00:01:41,204 --> 00:01:43,926

Bye!!!

48
00:01:48,763 --> 00:01:51,398
I want to know 
what your favorite animal eye is.

49
00:01:51,468 --> 00:01:53,647
Mine is the chameleon.
