1
00:00:12,600 --> 00:00:16,200
Of over a million species of animals on our planet, one species
2
00:00:16,200 --> 00:00:19,600
has come to dominate all other life-forms, and altered
3
00:00:19,600 --> 00:00:21,400
dramatically the face of the Earth.
4
00:00:22,000 --> 00:00:25,000
It's a species that, if we remove its protective layer of clothing,
5
00:00:25,000 --> 00:00:29,500
reveals a rather strange anatomy.
6
00:00:29,500 --> 00:00:35,200
A species I once referred to as the Naked Ape. Physically, the human being is
7
00:00:35,200 --> 00:00:40,200
a puny primate, with a vulnerable unprotected skin, with no natural weapon.
8
00:00:40,200 --> 00:00:40,300
9
00:00:40,300 --> 00:00:41,800
No armor, no sharp spines.
10
00:00:42,100 --> 00:00:47,800
No venom, no fangs or claws.
11
00:00:47,800 --> 00:00:49,700
Yet equipped with little more than an enlarged brain,
12
00:00:49,900 --> 00:00:53,300
this compulsively curious creature has come to dominate the
13
00:00:53,300 --> 00:00:54,400
natural world.
14
00:00:57,400 --> 00:01:00,800
What is the secret of its lavish, unprecedented success?
15
00:01:22,100 --> 00:01:25,400
Anatomically the human animal is unusual to say the least.
16
00:01:25,700 --> 00:01:28,800
Its lack of hair is unique among primates.
17
00:01:30,900 --> 00:01:35,000
Contrasting with other apes, its face has a protruding nose
18
00:01:35,000 --> 00:01:38,800
whites to the eyes and lips that are turned inside out.
19
00:01:42,200 --> 00:01:45,500
It's legs are long and straight and unlike any other mammal,
20
00:01:45,500 --> 00:01:46,900
it walks bipedally.
21
00:01:50,500 --> 00:01:53,100
The breasts of the female remain swollen throughout her
22
00:01:53,100 --> 00:01:57,100
adult life, even when they're not giving milk. Again a unique feature.
23
00:01:57,100 --> 00:02:02,400
There are a few surviving patches of hair including
24
00:02:02,400 --> 00:02:06,000
on the tops of the heads, in the armpits and around the genitals.
25
00:02:07,100 --> 00:02:09,800
The male has the largest penis of any primate.
26
00:02:10,900 --> 00:02:14,200
And the human animal is the only primate that possesses rounded
27
00:02:14,200 --> 00:02:18,000
fleshy buttocks. Altogether, these unique features make us
28
00:02:18,000 --> 00:02:20,200
a very strange ape indeed.
29
00:02:22,100 --> 00:02:25,400
And for a student of animal behavior,
30
00:02:25,400 --> 00:02:28,900
even more peculiar than its anatomy, are its activities in the wild.
31
00:02:37,500 --> 00:02:38,600
I'm a zoologist,
32
00:02:38,600 --> 00:02:42,900
and since man is an animal, I can see no reason why my work
33
00:02:42,900 --> 00:02:46,500
and also in this series, I shouldn't study this particular
34
00:02:46,500 --> 00:02:49,200
species in the same way that I've studied many other animals
35
00:02:49,200 --> 00:02:53,400
in the past. The secret is patient observation.
36
00:02:59,600 --> 00:03:03,100
For me, the ideal method is to go out into the field and study
37
00:03:03,100 --> 00:03:07,000
humans in their natural environment.
In the streets and parks,
38
00:03:07,000 --> 00:03:10,500
the shops and offices, the villages and cities
39
00:03:10,500 --> 00:03:14,300
to analyze their natural behavior as it happens in real life situations
40
00:03:14,300 --> 00:03:15,500
all over the world.
41
00:03:28,300 --> 00:03:31,300
Everywhere I go I'm struck by how similar all human beings
42
00:03:31,300 --> 00:03:34,000
are to one another in all important respects.
43
00:03:34,300 --> 00:03:37,600
Of course, there are many superficial differences and these
44
00:03:37,600 --> 00:03:40,600
are often so impressive that we pay too much attention to them
45
00:03:40,600 --> 00:03:43,900
and start treating one another as if we belong to different species
46
00:03:43,900 --> 00:03:49,600
with disastrous results. But despite all our variations in costume,
47
00:03:49,600 --> 00:03:53,600
ritual and belief, biologically, we're all astonishingly close
48
00:03:53,600 --> 00:03:58,800
to one another.
A fact which I find very reassuring.
49
00:03:58,800 --> 00:04:00,200
Back in the late 1960s.
50
00:04:00,200 --> 00:04:03,600
I was sitting in this very restaurant on the island of Malta
51
00:04:04,100 --> 00:04:05,200
talking to my publisher.
52
00:04:06,200 --> 00:04:08,500
I drew his attention to the fact that over the other side
53
00:04:08,500 --> 00:04:11,700
of the road were two men who were gesticulating in a particular way.
54
00:04:11,700 --> 00:04:15,000
The way they were holding their palms to one side was
55
00:04:15,000 --> 00:04:18,200
fascinating me, and he said, you know, you look at people
56
00:04:18,700 --> 00:04:21,390
the way that a bird watcher looks at birds, and I said,
57
00:04:21,390 --> 00:04:25,000
yeah, I suppose you could call me a man watcher.
58
00:04:25,000 --> 00:04:28,000
As soon as I said, it was as if I had fired a starting gun
59
00:04:28,000 --> 00:04:29,200
on a major new project.
60
00:04:29,200 --> 00:04:32,400
One that was to engross me for many years to come,
61
00:04:32,400 --> 00:04:34,100
and take me to over 60 different countries.
62
00:04:40,100 --> 00:04:43,200
It was wildly ambitious, but I decided to make a complete
63
00:04:43,200 --> 00:04:47,800
classification of all human actions, gestures, postures, expressions
64
00:04:48,600 --> 00:04:49,600
all over the world.
65
00:04:50,900 --> 00:04:52,400
And this was going to take a very long time.
66
00:04:53,600 --> 00:04:54,800
I was going to do for actions,
67
00:04:54,800 --> 00:04:57,100
what dictionary makers have done for words.
68
00:04:57,800 --> 00:05:01,100
I began making huge charts naming every facial expression,
69
00:05:01,100 --> 00:05:04,200
every gesticulation, every movement, every posture.
70
00:05:04,700 --> 00:05:08,000
I kept at it for month after month and eight years later,
71
00:05:08,300 --> 00:05:12,000
I'd completed the work and was able at last to introduce
72
00:05:12,000 --> 00:05:15,600
people to the fascinating subject of human body language.
73
00:05:17,400 --> 00:05:20,400
One of the first problems I encountered was that
74
00:05:20,400 --> 00:05:24,900
even the simplest human action, such as the handshake, has countless variations.
75
00:05:28,500 --> 00:05:33,000
Sometimes it's reduced to a mere palm touch,
76
00:05:33,000 --> 00:05:46,400
as with these Maasai elders in East Africa. But in other countries,
77
00:05:46,400 --> 00:05:50,500
it becomes more elaborate.
In Mali, in West Africa, the hand-shaker
78
00:05:50,500 --> 00:05:54,200
briefly touches his own forearm as the palms clasp.
79
00:05:58,000 --> 00:06:01,500
In Morocco, the hand shakers kiss one another's hands
80
00:06:01,500 --> 00:06:03,100
at the same time as clasping them.
81
00:06:06,000 --> 00:06:09,700
And in Turkey, these Kurdish farmers have taken this simple action
82
00:06:09,700 --> 00:06:13,100
and converted it into what amounts to a minor ritual.
83
00:06:14,500 --> 00:06:17,600
It's the local rule that they can't start bargaining until
84
00:06:17,600 --> 00:06:21,200
they're shaking hands and they have to keep on doing so until
85
00:06:21,200 --> 00:06:22,300
the deal is struck.
86
00:06:25,000 --> 00:06:29,000
The essential feature of handshaking is that it's an egalitarian act.
87
00:06:29,000 --> 00:06:32,500
Regardless of the social standing, the two people involved
88
00:06:32,500 --> 00:06:35,700
are momentarily performing identical actions.
89
00:06:38,800 --> 00:06:42,200
This meeting as equals that has spread around the world is
90
00:06:42,200 --> 00:06:46,300
comparatively recent.
In earlier times when greeting,
91
00:06:46,300 --> 00:06:49,700
it was common for the less important individuals to literally lower
92
00:06:49,700 --> 00:06:53,600
themselves as a sign of respect.
In some remote parts of the world
93
00:06:53,600 --> 00:06:57,700
we can still see this even today.
The Toda people of
94
00:06:57,700 --> 00:07:01,300
South India still perform this body lowering ritual with
95
00:07:01,300 --> 00:07:04,800
high status feet placed on low status heads.
96
00:07:23,700 --> 00:07:27,000
Despite their variations,
all these greetings have one thing
97
00:07:27,000 --> 00:07:27,700
in common.
98
00:07:28,000 --> 00:07:31,700
They're all fine-tuned to the precise context in which they occur.
99
00:07:34,700 --> 00:07:37,200
So many gestures have different meanings
in different places,
100
00:07:37,200 --> 00:07:39,900
you have to be quite careful
how you use your hands
101
00:07:40,200 --> 00:07:43,700
when you're in a market place in a foreign country.
102
00:07:43,700 --> 00:07:45,300
Now to me this means everything's fine. OK.
103
00:07:45,300 --> 00:07:48,300
But if I happened to be in the south of France,
104
00:07:48,300 --> 00:07:52,400
it would have a quite different meaning.
There, the ring shape made by the
105
00:07:52,400 --> 00:07:55,100
hand symbolizes a nought or a zero.
106
00:07:55,200 --> 00:07:59,900
So, in south of France it means zero,
or worthless. So you don't
107
00:07:59,900 --> 00:08:02,900
want to say the wine was great,
because in fact you're saying
108
00:08:02,900 --> 00:08:06,600
the wine was worthless.
It gets even worse if you go to Sardinia
109
00:08:06,600 --> 00:08:10,500
because there, the same gesture
is an obscenity, with the ring shape
110
00:08:10,500 --> 00:08:12,000
symbolizing an orifice.
111
00:08:12,400 --> 00:08:14,800
And if you think you're going to say
that something is great
112
00:08:14,800 --> 00:08:17,700
in Sardinia like this,
believe me, you'll be in trouble.
113
00:08:18,600 --> 00:08:20,800
There's another way that you can make mistakes with gestures
114
00:08:20,800 --> 00:08:24,700
as you move from place to place,
because, a single message
115
00:08:24,800 --> 00:08:28,400
is given in a different way
in different countries.
116
00:08:28,400 --> 00:08:31,200
The crazy sign.
How do you say to somebody you're crazy?
117
00:08:31,200 --> 00:08:33,700
Well here in Rome, you do this.
118
00:08:34,600 --> 00:08:38,200
But in England, I would probably do this,
the temple screw,
119
00:08:38,200 --> 00:08:41,700
saying he's got a screw loose.
Or I might say his brain is
120
00:08:41,700 --> 00:08:45,900
going round and round.
Or I might tap my head saying what's
121
00:08:45,900 --> 00:08:48,600
he think he's got inside his skull.
In some countries
122
00:08:48,600 --> 00:08:52,700
you do it with two hands.
It varies from place to place and if you
123
00:08:52,700 --> 00:08:55,600
go to Japan, you have to be careful because if you do it
124
00:08:55,600 --> 00:08:57,700
this way, it means he's intelligent.
125
00:08:57,700 --> 00:09:00,900
You have to do it in an anti-clockwise direction in Japan
126
00:09:01,100 --> 00:09:05,000
if you want to say that somebody is crazy.
So all over world
127
00:09:05,100 --> 00:09:08,200
the same message is given
in a slightly different way.
128
00:09:09,100 --> 00:09:11,900
One of the most obvious examples of this,
and one of the most dangerous
129
00:09:11,900 --> 00:09:16,100
is the insult gesture.
This Turkish pedestrian displays
130
00:09:16,100 --> 00:09:19,600
his anger with the thrust of a stiff forearm using his arm
131
00:09:19,600 --> 00:09:22,500
symbolically as an aggressively erect penis.
132
00:09:26,000 --> 00:09:30,200
A slightly more obscure insult is the corna or horn sign
133
00:09:30,200 --> 00:09:31,600
frequently seen in Italy.
134
00:09:31,800 --> 00:09:34,700
It implies that the victim of the insult is a cuckold.
135
00:09:34,700 --> 00:09:36,300
That his wife is unfaithful to him.
136
00:09:43,600 --> 00:09:46,600
In North America,
the most common insult is the middle finger jerk.
137
00:09:46,600 --> 00:09:50,300
Employing the index finger as a symbolic penis.
138
00:09:51,000 --> 00:09:53,900
This is an ancient Roman gesture
and is well known in many countries.
139
00:09:53,900 --> 00:09:59,100
Much more localized is the Greek muttsir.
140
00:09:59,300 --> 00:10:02,900
This dates back to Byzantine times and symbolizes excrement
141
00:10:02,900 --> 00:10:07,000
being pushed into the victims face.
142
00:10:07,000 --> 00:10:10,400
In Britain, the main insult
is a two-fingered gesture, which dates back
143
00:10:10,400 --> 00:10:11,700
to the Battle of Agincourt.
144
00:10:12,400 --> 00:10:15,400
It's a gesture that foreigners sometimes confuse
145
00:10:15,400 --> 00:10:16,300
with the V for victory sign.
146
00:10:16,300 --> 00:10:19,700
But that's performed with the hand the other way around.
147
00:10:22,500 --> 00:10:26,100
Most regional body language has a long and complicated history
148
00:10:26,200 --> 00:10:28,100
with the origins often forgotten.
149
00:10:29,500 --> 00:10:32,600
One of the special qualities of regional gestures is that
150
00:10:32,600 --> 00:10:34,500
they're amazingly conservative.
151
00:10:34,700 --> 00:10:37,500
They remain confined to their own particular area regardless
152
00:10:37,500 --> 00:10:39,800
of the fact that all around them national boundaries keep changing.
153
00:10:39,800 --> 00:10:43,700
As a result of this, within a particular country
154
00:10:43,700 --> 00:10:47,400
today, you can find what we could call a gesture frontier.
155
00:10:47,900 --> 00:10:51,300
A place where one gesture stops and another one begins.
156
00:10:51,900 --> 00:10:53,600
This is a gesture frontier behind me.
157
00:10:54,000 --> 00:10:58,100
It's a mountain range in central Italy.
And south of here
158
00:10:58,100 --> 00:10:59,000
in Naples,
159
00:10:59,300 --> 00:11:03,300
people use for example the head toss
when they're saying no.
160
00:11:03,300 --> 00:11:06,200
Up in the north, in Rome,
161
00:11:06,300 --> 00:11:08,700
they shake their heads from side to side when they're saying no.
162
00:11:08,700 --> 00:11:12,600
And we were amazed to find that here,
163
00:11:13,000 --> 00:11:16,100
at this mountain range, there's a very narrow area just a few miles
164
00:11:16,100 --> 00:11:20,300
where you get the switch from head tossing to head-shaking.
165
00:11:20,900 --> 00:11:24,600
The explanation of this switch is astonishing.
166
00:11:24,600 --> 00:11:29,100
In origin, the head toss is a Greek gesture
and many centuries ago
167
00:11:29,200 --> 00:11:32,600
the Ancient Greeks colonized
southern Italy and started to move north
168
00:11:32,900 --> 00:11:35,900
and it was here at this range
that they stopped their
169
00:11:35,900 --> 00:11:38,600
advance two and a half thousand years ago.
170
00:11:39,200 --> 00:11:42,800
And to this day, in the north,
people still give the typical
171
00:11:42,800 --> 00:11:45,500
European head shake when saying no.
172
00:11:48,700 --> 00:11:51,900
While in the South,
they still give the ancient Greek head toss
173
00:11:51,900 --> 00:11:55,500
and this difference has survived
despite all the mobility
174
00:11:55,500 --> 00:11:59,000
of modern life, and the spread
of films and television programs.
175
00:11:59,500 --> 00:12:02,000
The old gesture frontier remains.
176
00:12:08,400 --> 00:12:11,600
Yes signals made with the head
are just as complicated as no signals.
177
00:12:11,600 --> 00:12:14,500
In most parts of the world,
178
00:12:14,500 --> 00:12:18,700
people nod the head up and down when saying yes.
Many people mistakenly
179
00:12:18,700 --> 00:12:22,400
assume that this action is completely global,
180
00:12:22,400 --> 00:12:23,100
but this isn't the case.
181
00:12:23,700 --> 00:12:26,300
There are two areas
where something else happens.
182
00:12:26,900 --> 00:12:30,700
One of them is India,
where instead of being nodded,
183
00:12:30,700 --> 00:12:35,300
the head is wobbled from side to side
when saying yes.
184
00:12:35,300 --> 00:12:40,100
To visitors, this looks like a maybe, but it's not.
It's a sign of definite agreement.
185
00:12:47,500 --> 00:12:50,800
When your taxi driver agrees with you,
you can see his head
186
00:12:50,800 --> 00:12:54,200
rolling from side to side.
You get the impression that he's undecided.
187
00:12:54,200 --> 00:13:02,600
But every wobble he makes means "yes".
188
00:13:09,900 --> 00:13:13,200
In another region altogether,
it's not just the visitors
189
00:13:13,200 --> 00:13:16,400
who are confused,
even the inhabitants are not always sure
190
00:13:16,400 --> 00:13:19,000
what's going on. Here in Bulgaria,
191
00:13:19,200 --> 00:13:23,400
they use both the head nod
and the head wobble when saying yes,
192
00:13:23,400 --> 00:13:27,200
which creates total confusion!
Why on earth they should
193
00:13:27,200 --> 00:13:29,500
do this remains a mystery, even to them.
194
00:13:50,300 --> 00:13:52,600
Although gestures often persist for hundreds,
195
00:13:52,600 --> 00:13:54,200
or even thousands of years,
196
00:13:54,500 --> 00:13:57,200
sometimes they may change their meaning as they're passed
197
00:13:57,200 --> 00:13:59,200
on from generation to generation.
198
00:13:59,900 --> 00:14:04,900
We all think we know what the popular thumbs-up and thumbs-down gestures mean.
199
00:14:30,000 --> 00:14:33,800
If we go to the cinema, we're left in little doubt
200
00:14:33,800 --> 00:14:39,200
as to the significance of these gestures.
The thumbs up for good
201
00:14:39,300 --> 00:14:42,800
and the thumbs down for bad
are very well-known gestures,
202
00:14:42,800 --> 00:14:44,600
and many people can tell you how they began.
203
00:14:44,800 --> 00:14:47,400
It was here in the Colosseum in Rome.
204
00:14:48,400 --> 00:14:52,400
If a gladiator at the end of a fight
was to be spared, the crowd
205
00:14:52,400 --> 00:14:55,500
gave him a thumbs up sign.
If he was to be slain,
206
00:14:55,500 --> 00:14:57,100
it was a thumbs-down sign.
207
00:14:57,200 --> 00:14:58,300
That's the popular story.
208
00:14:58,300 --> 00:14:59,500
There's just one catch.
209
00:14:59,500 --> 00:15:00,800
It's completely false.
210
00:15:01,400 --> 00:15:05,000
It never happened like that.
In ancient times if the Gladiator
211
00:15:05,000 --> 00:15:06,400
was to be spared,
212
00:15:06,700 --> 00:15:09,000
they gave him a covered up thumb.
213
00:15:09,300 --> 00:15:13,200
The compressed or squashed sign.
214
00:15:13,200 --> 00:15:14,000
They hid their thumbs.
215
00:15:14,200 --> 00:15:17,700
If he was to be slain, then they mimed the act of stabbing him
216
00:15:17,700 --> 00:15:20,600
with a sword like this.
And because they were high up of course,
217
00:15:20,600 --> 00:15:23,200
they stabbed downwards like that.
218
00:15:23,700 --> 00:15:25,100
That's the truth of the matter.
219
00:15:25,500 --> 00:15:27,600
And the next time you go to the movies,
220
00:15:27,600 --> 00:15:31,100
if you happen to see the thumbs up, you'll just have to take
221
00:15:31,100 --> 00:15:32,400
it with a pinch of salt.
222
00:15:35,900 --> 00:15:39,800
It's almost certain that our ancestors used gestures to communicate
223
00:15:39,800 --> 00:15:43,400
specific information long before they had a spoken language.
224
00:15:43,900 --> 00:15:47,300
Even today, with words as our main form of communication,
225
00:15:47,500 --> 00:15:50,300
there are still situations where gestures have a definite advantage.
226
00:15:54,300 --> 00:15:57,500
For example, they can communicate information
227
00:15:57,500 --> 00:16:01,200
over a far greater distance than would be possible by shouting.
228
00:16:01,800 --> 00:16:05,800
At racetracks in England, the white glove Tic Tac men signal
229
00:16:05,800 --> 00:16:08,400
changes in the betting odds to the bookies so that they can
230
00:16:08,400 --> 00:16:09,800
keep up with the alterations
231
00:16:09,800 --> 00:16:18,900
their rivals may be making.
The flashing movements of the
232
00:16:18,900 --> 00:16:22,800
white gloves can be seen even at night and at a great distance.
233
00:16:42,100 --> 00:16:45,700
In some sports, a gestural sign language not only
234
00:16:45,700 --> 00:16:49,300
conveys information over a great distance, but also allows
235
00:16:49,300 --> 00:16:51,200
messages to be kept secret.
236
00:16:59,400 --> 00:17:03,300
The coach of an American football team transmits complex
237
00:17:03,300 --> 00:17:06,900
signals to his quarterback using coded hand signals that
238
00:17:06,900 --> 00:17:09,900
conceal his intentions from the opposing team.
239
00:17:24,400 --> 00:17:28,500
Even if the opposing team does manage
to crack the gestural code
240
00:17:28,500 --> 00:17:32,000
at any one time, it's being constantly changed to confuse them.
241
00:17:54,000 --> 00:17:58,100
On the floor of the Bombay Stock Exchange,
242
00:17:58,100 --> 00:18:02,300
hand gestures provide a powerful tool
when competing for attention.
243
00:18:02,300 --> 00:18:05,600
The frantic sell and buy signals indicated by the position of
244
00:18:05,600 --> 00:18:08,600
the hands can be the basis of huge deals.
245
00:18:09,100 --> 00:18:12,200
An insistent flick of the fingers
being the only way to attract
246
00:18:12,200 --> 00:18:14,600
attention above the roar of the crowd.
247
00:18:39,400 --> 00:18:42,000
In the eerie silence of the Australian outback
248
00:18:42,000 --> 00:18:46,600
these two Warlpiri women are conversing quite adequately by gestures alone.
249
00:18:46,600 --> 00:18:51,300
Now, they're not deaf,
and they're perfectly capable of speech.
250
00:18:51,300 --> 00:18:54,200
But local custom
demands that as an act of mourning,
251
00:18:54,400 --> 00:18:57,700
they don't utter a word for months
after a tribesman has died.
252
00:18:58,700 --> 00:19:01,100
It's their version of wearing black.
253
00:19:16,500 --> 00:19:18,400
Clearly, gestures are important to us.
254
00:19:18,400 --> 00:19:21,500
But why are we so much better
at signaling with our hands
255
00:19:21,500 --> 00:19:22,900
than other animals?
256
00:19:23,600 --> 00:19:26,900
The answer of course is that
we are the only mammals
257
00:19:26,900 --> 00:19:27,900
that are bipedal.
258
00:19:28,300 --> 00:19:31,800
They are all quadrupedal.
They walk along on all fours.
259
00:19:31,800 --> 00:19:35,500
But when we stood up on our hind legs
millions of years ago
260
00:19:35,500 --> 00:19:39,900
here in Africa, we freed our hands
from the business of walking.
261
00:19:40,200 --> 00:19:41,500
We freed them from the chore
262
00:19:41,800 --> 00:19:44,600
of locomotion and that was
what enabled them to become the
263
00:19:44,800 --> 00:19:48,100
flexible, gesticulating hands that we have today.
264
00:19:59,300 --> 00:20:02,200
In order to appreciate what an immense impact the simple act
265
00:20:02,200 --> 00:20:06,000
of standing up had on our primeval ancestors, it's only
266
00:20:06,000 --> 00:20:09,900
necessary to watch our nearest living relatives,
the chimpanzees.
267
00:20:17,100 --> 00:20:20,900
When they're moving about in their natural habitat, their hands
268
00:20:21,000 --> 00:20:24,200
still have to function for much of the time as plodding front feet
269
00:20:24,200 --> 00:20:27,600
and this prevents them from becoming highly developed
270
00:20:27,700 --> 00:20:29,700
as expressive organs of gesture.
271
00:20:43,600 --> 00:20:47,000
The front feet can operate successfully as grasping hands,
272
00:20:47,000 --> 00:20:50,200
for example, when holding a baby, but they never develop
273
00:20:50,200 --> 00:20:55,200
the subtlety of movement that we see in our own species.
274
00:20:55,200 --> 00:21:01,000
Elegant gesturing remains the prerogative
of the uniquely bipedal naked ape.
275
00:21:01,100 --> 00:21:01,100
276
00:21:05,500 --> 00:21:09,000
So far all the gestures that I've described have been regional,
277
00:21:09,300 --> 00:21:13,200
and they're used consciously
to replace speech, like the deliberate
278
00:21:13,200 --> 00:21:16,100
directions of this policeman,
but there's another type of
279
00:21:16,100 --> 00:21:20,300
gesture all together.
Unconscious hand movements usually
280
00:21:20,300 --> 00:21:22,100
referred to as gesticulation.
281
00:21:25,600 --> 00:21:29,200
Instead of replacing speech,
they accompany it.
282
00:21:43,200 --> 00:21:46,500
This type of hand signal
has been christened the Baton gesture
283
00:21:46,500 --> 00:21:50,000
because it beats time to our words
and emphasizes the points we're making
284
00:21:55,000 --> 00:21:58,300
But Baton gestures do much more than merely beat time.
285
00:21:58,600 --> 00:22:02,100
They also indicate our changing moods.
The posture of the hand
286
00:22:02,100 --> 00:22:06,500
as it beats the air, revealing
the emotional state of the speaker.
287
00:22:06,500 --> 00:22:06,500
288
00:22:35,000 --> 00:22:39,600
Here at Speakers' Corner in London's Hyde Park,
a veritable gallery
289
00:22:39,600 --> 00:22:42,300
of human baton gestures is on display.
290
00:22:42,700 --> 00:22:44,000
Let's watch for a moment.
291
00:22:59,000 --> 00:22:59,800
Now let's take a closer
292
00:22:59,800 --> 00:23:03,200
look at two of his gestures.
Slowing it down,
293
00:23:03,300 --> 00:23:06,800
his first gesture is
a repelling action using his hand as
294
00:23:06,800 --> 00:23:09,700
if it were pushing away the intruder,
295
00:23:09,700 --> 00:23:14,000
but without making physical contact.
These are obvious enough, but what does he do next?
296
00:23:18,000 --> 00:23:22,300
As the intruder leaves,
he draws his chosen audience
297
00:23:22,300 --> 00:23:26,000
back towards him
using an air grasp gesture, there.
298
00:23:29,700 --> 00:23:33,800
Another speaker is about
to mention a precise date, and unconsciously
299
00:23:33,800 --> 00:23:36,900
accompanies this with a precision gesture, as if holding
300
00:23:36,900 --> 00:23:40,800
a small object with great delicacy between his thumb and forefinger.
301
00:23:50,000 --> 00:23:52,400
A third speaker is in a more aggressive mood.
302
00:23:52,900 --> 00:23:56,900
He's using not a precision grip,
but a power grip,
303
00:23:56,900 --> 00:24:00,800
thrusting his clenched fist at the audience. The power of his fist reflecting
304
00:24:00,800 --> 00:24:02,300
the power of his argument.
305
00:24:03,300 --> 00:24:06,700
But now he switches to the raised forefinger.
306
00:24:06,700 --> 00:24:09,400
Beating his listeners over the head with his small symbolic club.
307
00:24:10,500 --> 00:24:14,900
And finally he extends his hands
palm up in an imploring gesture,
308
00:24:15,100 --> 00:24:16,600
begging them to agree with him.
309
00:24:28,600 --> 00:24:32,700
By contrast, this speaker employs the palm down gesture.
310
00:24:32,700 --> 00:24:35,600
A more dominant action in which he attempts to calm his audience
311
00:24:35,600 --> 00:24:38,800
by symbolically patting them on the head, as if they're unruly children.
312
00:24:42,800 --> 00:24:44,000
Finally this man introduces the
313
00:24:44,000 --> 00:24:47,500
hand chop gesture.
A decisive gesture in which his symbolically
314
00:24:47,500 --> 00:24:51,000
tries to cut through the argument as if with a sharp blade.
315
00:25:02,100 --> 00:25:06,000
The urge to express our emotions with our hands is so strong
316
00:25:06,100 --> 00:25:08,900
that we continue to gesticulate even when the person we're
317
00:25:08,900 --> 00:25:10,000
talking to, is miles away,
318
00:25:10,100 --> 00:25:12,500
at the other end of a telephone line.
319
00:25:31,600 --> 00:25:35,200
The urge to communicate by body language is so deeply ingrained
320
00:25:35,400 --> 00:25:39,100
that if we happen to be Japanese, we even bow respectfully
321
00:25:39,100 --> 00:25:41,300
to our remote invisible companion.
322
00:25:44,100 --> 00:25:47,000
But there's another whole facet of body language that conveys
323
00:25:47,000 --> 00:25:49,400
our emotions with even greater subtlety.
324
00:25:50,200 --> 00:25:53,600
We humans have the most expressive faces in the entire animal kingdom.
325
00:25:53,600 --> 00:25:57,500
We take our expressions rather for granted.
326
00:25:57,600 --> 00:26:00,200
But if we trace them back to their origins, it's interesting
327
00:26:00,200 --> 00:26:01,900
to see how they evolved.
328
00:26:06,800 --> 00:26:10,700
The chimpanzee's face is almost as expressive as the human's,
329
00:26:11,000 --> 00:26:14,100
and if we watch these apes in the wild,
we can begin to see
330
00:26:14,100 --> 00:26:17,000
how we acquired our own highly mobile faces.
331
00:26:17,900 --> 00:26:21,400
Originally, facial muscles were needed not for communication,
332
00:26:21,700 --> 00:26:26,800
but for other more basic functions.
333
00:26:26,800 --> 00:26:30,900
To move the lips for instance,
improving their role in drinking and feeding.
334
00:26:30,900 --> 00:26:34,500
As the apes suck, chew and bite,
their powerful, sensitive lips
335
00:26:34,500 --> 00:26:37,800
explore each object as it comes into contact with the mouth.
336
00:26:49,900 --> 00:26:53,000
This involves a great deal of pulling and stretching
337
00:26:53,000 --> 00:26:56,200
and when they're young, the infant apes employ their long lips
338
00:26:56,200 --> 00:26:59,300
as valuable sucking organs,
squeezing milk from their mother's nipples.
339
00:27:06,300 --> 00:27:10,400
But even the chimpanzee is no match
for the rubber faced human being.
340
00:27:10,400 --> 00:27:30,000
341
00:27:34,200 --> 00:27:36,300
If we could see below the surface
342
00:27:36,300 --> 00:27:39,400
of the human face, we'd discover
the most complicated set
343
00:27:39,400 --> 00:27:41,600
of facial muscles in the world.
344
00:27:55,200 --> 00:27:58,000
These muscles give us a huge range of expressions.
345
00:28:02,700 --> 00:28:05,600
Some big and bold. Others extremely subtle.
346
00:28:15,900 --> 00:28:19,000
But humans and chimps don't just share a flexible face.
347
00:28:19,200 --> 00:28:21,700
We also share many of the same expressions.
348
00:28:22,100 --> 00:28:24,000
It's not hard for us to appreciate that
349
00:28:24,000 --> 00:28:28,200
these young apes are in a playful mood
by simply looking at their faces.
350
00:28:28,200 --> 00:28:28,300
351
00:28:36,300 --> 00:28:39,100
And if we watch the way in which chimps work themselves up
352
00:28:39,100 --> 00:28:40,400
into a violent mood,
353
00:28:40,500 --> 00:28:42,900
it's easy for us to understand what's happening.
354
00:28:55,900 --> 00:28:59,100
Whenever an animal goes on the attack,
it's always slightly
355
00:28:59,100 --> 00:29:01,900
fearful of retaliation. As a result,
356
00:29:02,000 --> 00:29:05,900
we see a face in conflict
The tightness of the lips around
357
00:29:05,900 --> 00:29:09,200
the mouth is a sure sign of primate aggression.
358
00:29:09,200 --> 00:29:12,100
While the lowered eyebrows indicate that the attacker is protecting
359
00:29:12,100 --> 00:29:13,600
its eyes in case of a fight.
360
00:29:17,800 --> 00:29:21,500
The same tight-lipped face is also seen in our own species
361
00:29:21,600 --> 00:29:23,800
in moments of great emotional intensity.
362
00:29:28,300 --> 00:29:38,300
363
00:29:38,300 --> 00:29:40,300
There it is.
The tight mouth of animus.
364
00:29:41,900 --> 00:29:43,200
This leaves
365
00:29:43,200 --> 00:29:46,900
no doubt as to the mood of these women, especially when combined
366
00:29:46,900 --> 00:29:48,600
with an intense stare.
367
00:29:50,500 --> 00:29:54,000
One of the most primeval of all facial expressions
is the staring eye.
368
00:29:54,000 --> 00:29:56,600
It's something we share with other animals,
369
00:29:56,600 --> 00:30:01,100
and it's always threatening.
Because of this, in earlier centuries,
370
00:30:01,100 --> 00:30:04,800
people thought there was something they called The Evil Eye.
371
00:30:04,800 --> 00:30:08,500
A mystical force that by staring at them could do them harm.
372
00:30:08,500 --> 00:30:10,000
To protect themselves against this evil eye,
373
00:30:10,200 --> 00:30:13,500
they would often try to out steer it.
To do this,
374
00:30:13,800 --> 00:30:16,700
they made effigies of eyes, which were unblinking and could
375
00:30:16,700 --> 00:30:20,000
perform a permanent stare
to frighten away the evil spirits.
376
00:30:20,600 --> 00:30:23,200
Fishermen when they went to sea, wanted to protect their boats,
377
00:30:23,200 --> 00:30:26,800
and they did so by giving their boats a staring eye.
378
00:30:31,900 --> 00:30:34,900
And all over the Mediterranean, fishing boats are protected
379
00:30:34,900 --> 00:30:38,500
with elaborately painted and eternally unblinking eyes.
380
00:30:41,700 --> 00:30:46,300
Because hard stares are so assertive,
some military and prison
381
00:30:46,300 --> 00:30:50,200
rituals employ them in a special way.
At this correctional
382
00:30:50,200 --> 00:30:51,500
camp in Maryland,
383
00:30:51,600 --> 00:30:54,900
these prisoners are forbidden to stare,
even to glance,
384
00:30:54,900 --> 00:30:55,900
at their prison officers.
385
00:30:56,700 --> 00:30:59,700
The officers, who are not allowed to lay a hand on the prisoners
386
00:31:00,000 --> 00:31:03,200
make their dominance felt by the most direct and intense
387
00:31:03,200 --> 00:31:07,400
staring they can muster.
And the effect is one of acute intimidation
388
00:31:07,700 --> 00:31:09,800
and almost painful humiliation.
389
00:31:11,000 --> 00:31:12,400
390
00:31:12,900 --> 00:31:17,000
391
00:31:17,000 --> 00:31:17,900
392
00:31:17,900 --> 00:31:19,000
393
00:31:19,000 --> 00:31:19,900
394
00:31:19,900 --> 00:31:20,700
395
00:31:21,500 --> 00:31:25,700
396
00:31:25,700 --> 00:31:42,400
397
00:31:42,600 --> 00:31:43,400
398
00:31:43,400 --> 00:31:43,900
399
00:31:44,600 --> 00:31:46,800
400
00:31:47,300 --> 00:31:48,100
401
00:31:48,100 --> 00:31:49,100
402
00:31:49,100 --> 00:31:51,300
403
00:31:51,300 --> 00:31:53,900
404
00:31:55,300 --> 00:31:57,900
405
00:32:05,400 --> 00:32:08,100
If you thought that staring was pretty intimidating,
406
00:32:08,100 --> 00:32:10,400
there's one culture that takes it even further.
407
00:32:22,300 --> 00:32:23,600
408
00:32:23,900 --> 00:32:37,800
409
00:32:37,900 --> 00:32:41,300
This is the Maori Haka.
The aggressive challenge of the
410
00:32:41,300 --> 00:32:43,600
indigenous people of New Zealand.
411
00:32:43,800 --> 00:32:48,200
An ancient threat display,
still employed today in a modern context.
412
00:33:17,200 --> 00:33:20,300
Taking another look at those aggressive chimpanzees, what happens
413
00:33:20,300 --> 00:33:23,700
if they start to become alarmed and fearful.
If the courage
414
00:33:23,700 --> 00:33:25,000
begins to desert them?
415
00:33:34,000 --> 00:33:36,900
As they become more and more afraid, their expressions undergo
416
00:33:36,900 --> 00:33:40,600
an important change.
Their mouth corners are pulled back further
417
00:33:40,600 --> 00:33:41,300
and further.
418
00:33:41,700 --> 00:33:44,900
This is the typical fear face of all primates,
419
00:33:44,900 --> 00:33:46,100
including our own species.
420
00:34:09,600 --> 00:34:13,000
The best way to prove just how closely we share this expression
421
00:34:13,300 --> 00:34:16,500
is to examine the faces of the panic-stricken customers on
422
00:34:16,600 --> 00:34:21,800
the latest fairground terror ride.
The spiralling Nemesis.
423
00:34:21,800 --> 00:34:22,900
Just as with frightened chimps,
424
00:34:22,900 --> 00:34:26,000
these mouth corners are pulled right back, exposing all the teeth.
425
00:34:40,000 --> 00:34:42,690
The strange feature of this expression is that it
426
00:34:42,690 --> 00:34:45,690
looks in some respects like the human smile.
427
00:34:50,500 --> 00:34:54,190
Smiling is a uniquely human expression that has evolved from
428
00:34:54,190 --> 00:34:55,800
the ancient fear face.
429
00:34:56,500 --> 00:34:59,500
This may sound odd because we think of smiling as friendly,
430
00:34:59,500 --> 00:35:03,400
not fearful. But there's a crucial link between the two.
431
00:35:03,400 --> 00:35:07,000
The fear face is sometimes used as a submissive signal saying
432
00:35:07,000 --> 00:35:07,800
in effect.
433
00:35:07,800 --> 00:35:08,700
I'm scared,
434
00:35:08,700 --> 00:35:09,300
therefore
435
00:35:09,500 --> 00:35:10,600
I'm not a threat to you.
436
00:35:10,800 --> 00:35:11,400
In other words,
437
00:35:11,400 --> 00:35:13,500
it's an anti aggressive action.
438
00:35:13,900 --> 00:35:18,000
It's only a small step from "I am not a aggressive"
439
00:35:18,000 --> 00:35:21,000
to "I am friendly".
And that's how the human smile evolved.
440
00:35:24,600 --> 00:35:28,000
Because of the smile's anti aggressive origins,
441
00:35:28,000 --> 00:35:31,700
witnessing it makes onlookers feel at ease and responsive to the smiler
442
00:35:32,000 --> 00:35:32,800
For this reason,
443
00:35:32,900 --> 00:35:36,700
it's been a mainstay of commercial advertising for many years.
444
00:35:40,300 --> 00:35:44,300
445
00:35:44,300 --> 00:35:48,900
446
00:35:50,900 --> 00:35:53,300
447
00:35:53,300 --> 00:35:57,100
The problem for
these professional smilers however,
448
00:35:57,100 --> 00:36:00,700
is that it's difficult to fake the expression perfectly.
449
00:36:01,300 --> 00:36:03,700
The fixed smile gives the game away.
450
00:36:29,300 --> 00:36:32,200
For synchronized swimmers, the physical exertions of their
451
00:36:32,200 --> 00:36:36,000
sport make it even harder to fake a convincing smile.
452
00:36:36,800 --> 00:36:40,300
They have to keep on smiling to impress the judges,
453
00:36:40,300 --> 00:36:41,000
but it's not easy.
454
00:36:44,100 --> 00:36:47,700
One of the best places to observe the false smile is on the
455
00:36:47,700 --> 00:36:50,600
faces of the beachside photographer's customers.
456
00:36:51,900 --> 00:36:54,600
457
00:36:56,800 --> 00:37:00,800
But how precisely do we know that this smile
458
00:37:01,000 --> 00:37:05,200
falls short of being convincing?
The essential feature
459
00:37:05,200 --> 00:37:08,100
is that the specialized muscles that pull the mouth corners up,
460
00:37:08,100 --> 00:37:12,100
and the ones around the eyes that create the smiling eyes
461
00:37:12,300 --> 00:37:13,100
are both much
462
00:37:13,200 --> 00:37:16,400
harder to control consciously, than the more ancient ones that
463
00:37:16,400 --> 00:37:20,100
simply pull the mouth corners back.
No matter how hard we try,
464
00:37:20,100 --> 00:37:23,600
we can't fabricate the perfect smile.
465
00:37:27,100 --> 00:37:30,800
This incredibly strong link between our facial expressions
466
00:37:30,800 --> 00:37:33,900
and the inner workings of our body has been put to very good
467
00:37:33,900 --> 00:37:37,900
use by imaginative doctors in America who've taken the radical
468
00:37:37,900 --> 00:37:41,100
step of clowning in hospital wards.
469
00:37:51,000 --> 00:37:55,300
470
00:37:55,300 --> 00:37:56,900
471
00:37:56,900 --> 00:38:00,400
Although this may appear to be a bizarre form of medical care,
472
00:38:00,400 --> 00:38:04,800
its impact is extraordinary.
By making patients smile and laugh,
473
00:38:05,000 --> 00:38:09,200
their pain levels are reduced.
The happy facial expressions
474
00:38:09,200 --> 00:38:12,500
actually release endorphins,
the body's natural pain killers
475
00:38:12,600 --> 00:38:13,800
into their systems.
476
00:38:17,600 --> 00:38:20,300
477
00:38:20,400 --> 00:38:21,900
478
00:38:32,800 --> 00:38:36,500
479
00:38:36,500 --> 00:38:39,700
Amazingly the laughter created
by this clowning works as well
480
00:38:39,800 --> 00:38:46,100
as any pain-killing drug.
Such is the power of human body language.
481
00:38:46,100 --> 00:38:48,300
482
00:39:02,100 --> 00:39:05,000
Because our body language reveals our true feelings,
483
00:39:05,000 --> 00:39:08,600
we often try to suppress it
To hide our fears and anxieties,
484
00:39:08,600 --> 00:39:12,600
our longings and our hostilities.
But it's such an efficient
485
00:39:12,600 --> 00:39:16,200
communication system that we usually give away a few telltale signs.
486
00:39:16,200 --> 00:39:20,200
Now for most of us, that's an everyday social challenge.
487
00:39:20,800 --> 00:39:21,600
For some people
488
00:39:21,700 --> 00:39:26,000
it's much more than that.
For professional poker players,
489
00:39:26,200 --> 00:39:30,100
the suppression of body language is a way of life.
490
00:39:30,100 --> 00:39:34,100
For them, even the tiniest hint of emotion can cost a fortune.
491
00:39:34,700 --> 00:39:38,600
Here at the annual World Poker contest in Las Vegas
492
00:39:38,600 --> 00:39:42,600
a million dollars in cash is piled onto the table to be won or lost
493
00:39:42,600 --> 00:39:46,900
on the final play of the cards.
The finalists around the table
494
00:39:47,000 --> 00:39:49,900
are the best players in the world and needless to say they
495
00:39:49,900 --> 00:39:52,000
they are masters of body language control.
496
00:39:52,500 --> 00:39:55,200
They epitomize the so-called poker face.
497
00:39:56,100 --> 00:39:59,700
But even they are not entirely immune to the urges of human body language.
498
00:40:01,700 --> 00:40:04,700
Careful studies of the tell-tale signs of poker players
499
00:40:04,700 --> 00:40:08,300
have revealed that there are several vital clues
500
00:40:08,300 --> 00:40:12,600
that can tell you when a hand is good or bad, and when a player is bluffing.
501
00:40:13,600 --> 00:40:16,600
When a player has a bad hand
502
00:40:16,600 --> 00:40:18,200
he stares at his cards a little longer.
503
00:40:30,200 --> 00:40:34,200
When a player has a good hand,
his blink rate increases slightly.
504
00:40:40,900 --> 00:40:44,700
When he has a good hand,
he looks away for a split second.
505
00:40:48,400 --> 00:40:54,500
When he has a bad hand,
he bets with a flourish.
506
00:40:54,500 --> 00:40:57,700
But these particular players, world champions,
in addition to being able
507
00:40:57,700 --> 00:41:00,700
to suppress their own facial expressions and their telltale gestures,
508
00:41:00,700 --> 00:41:05,200
are also masters of reading the
body language of their competitors.
509
00:41:05,200 --> 00:41:05,200
510
00:41:06,200 --> 00:41:23,700
511
00:41:23,700 --> 00:41:25,400
This is the victor, but just watch his face.
512
00:41:25,500 --> 00:41:28,900
This man has just won a million dollars, but his expressions
513
00:41:28,900 --> 00:41:30,500
are so tightly under control
514
00:41:30,500 --> 00:41:32,800
that even now, he cannot show any emotion.
515
00:41:32,800 --> 00:41:33,700
There's no smile.
516
00:41:33,800 --> 00:41:36,000
No shouting for joy.
His poker face is a mask.
517
00:41:36,200 --> 00:41:44,300
All he allows himself eventually is a little jab
518
00:41:44,300 --> 00:41:46,600
in the air with a triumphant forefinger.
519
00:41:49,700 --> 00:41:53,700
Most of us would make poor poker players because we're so bad at lying
520
00:41:53,700 --> 00:41:56,100
We give away our true feelings
521
00:41:56,100 --> 00:41:57,300
despite all our efforts to conceal them.
522
00:42:03,000 --> 00:42:05,900
This woman has just been accused of stealing somebody's purse,
523
00:42:06,100 --> 00:42:07,900
and just by looking at her body language,
524
00:42:07,900 --> 00:42:11,000
it's possible to spot certain clues that suggest that her
525
00:42:11,000 --> 00:42:12,500
denials are false.
526
00:42:13,700 --> 00:42:14,000
527
00:42:14,000 --> 00:42:14,700
528
00:42:22,100 --> 00:42:24,500
She brings her hand up to her mouth
529
00:42:24,600 --> 00:42:28,400
as if to hide the lie that she's telling.
Face touching is
530
00:42:28,400 --> 00:42:30,300
often a sign of attempted deception.
531
00:42:33,900 --> 00:42:34,900
How'd you get the purse?
532
00:42:35,500 --> 00:42:36,400
I got a ride.
533
00:42:37,800 --> 00:42:38,700
Where'd you find it?
534
00:42:39,300 --> 00:42:41,400
It was on the floor and I automatically thought it was mine cos...
535
00:42:41,400 --> 00:42:45,000
She uses the hand shrug gesture.
An unconscious
536
00:42:45,000 --> 00:42:49,400
disclaimer that usually increases in frequency when lying is taking place.
537
00:42:49,400 --> 00:42:49,500
538
00:42:50,800 --> 00:42:53,900
Well, if you thought it was yours and you just got to tell...
539
00:42:53,900 --> 00:42:57,600
And her eyes blink and close more than usual, in an unconscious
540
00:42:57,600 --> 00:43:01,000
attempt to shut out the outside world.
To cut herself off
541
00:43:01,200 --> 00:43:02,800
from the tension of the lie.
542
00:43:03,400 --> 00:43:05,700
543
00:43:05,700 --> 00:43:09,000
544
00:43:09,200 --> 00:43:09,900
545
00:43:10,200 --> 00:43:12,400
546
00:43:12,400 --> 00:43:13,400
547
00:43:13,400 --> 00:43:14,200
548
00:43:14,200 --> 00:43:14,800
549
00:43:15,000 --> 00:43:15,400
550
00:43:16,600 --> 00:43:18,400
551
00:43:18,400 --> 00:43:19,100
552
00:43:21,200 --> 00:43:23,800
Some people seem to think body language is trivial,
553
00:43:23,800 --> 00:43:27,700
but it should be clear by now that this is not the case.
554
00:43:27,700 --> 00:43:29,100
Indeed in moments of desperation,
555
00:43:29,100 --> 00:43:31,000
we turn not just to spoken language,
556
00:43:31,100 --> 00:43:34,000
but beyond that to the more primeval language of the body.
557
00:43:34,000 --> 00:43:38,000
A signaling system that was used by our ancestors
558
00:43:38,000 --> 00:43:41,400
for millions of years before the first human words were uttered.
559
00:43:41,700 --> 00:43:44,800
And one that can still play a crucial role in ensuring
560
00:43:44,800 --> 00:43:46,300
an individual's survival.
561
00:43:47,300 --> 00:43:50,300
But even more far-reaching than this,
body language is so
562
00:43:50,300 --> 00:43:53,500
powerful that it can change the course of history and affect the behavior
563
00:43:53,500 --> 00:43:57,500
of literally millions of people.
A fact that tyrants have not overlooked.
564
00:43:57,600 --> 00:43:58,800
565
00:44:19,800 --> 00:44:22,800
For me, body language is far more than just a fascinating
566
00:44:22,800 --> 00:44:24,500
area of human biology.
567
00:44:25,000 --> 00:44:28,900
It's at the core of a whole new science.
The study of human behaviour
568
00:44:28,900 --> 00:44:32,700
from a zoological perspective.
569
00:44:32,700 --> 00:44:36,500
And for this series too,
body watching is only the beginning.
570
00:44:36,500 --> 00:44:38,800
Turning a zoological eye towards our own species,
571
00:44:39,200 --> 00:44:42,200
I'll be looking at the commonplace,
as well as the more unusual
572
00:44:42,200 --> 00:44:46,300
actions of the human animal.
Why for example, for a species
573
00:44:46,300 --> 00:44:49,800
which so often lives in a state of extreme overpopulation,
574
00:44:50,100 --> 00:44:54,500
is aggressive behavior like this the exception rather than the rule?
575
00:44:54,500 --> 00:44:54,500
576
00:44:56,600 --> 00:44:59,600
In fact, for the vast majority of the time,
the human animal
577
00:44:59,600 --> 00:45:03,000
goes about its business in an amazingly ordered world.
578
00:45:03,000 --> 00:45:07,000
Every individual, even in the vast social system of a city, is aware
579
00:45:07,000 --> 00:45:10,500
of fitting into a very precise position in the social pattern.
580
00:45:13,900 --> 00:45:16,600
I'll be looking at the human animal's sexual behavior.
581
00:45:17,000 --> 00:45:20,400
What biological mechanisms are at work when we choose a partner?
582
00:45:21,500 --> 00:45:25,200
And what influences why we find certain people attractive, and others not.
583
00:45:25,200 --> 00:45:25,200
584
00:45:32,700 --> 00:45:35,700
When it comes to the courtship ritual, what are our species
585
00:45:35,700 --> 00:45:37,100
typical behavior patterns?
586
00:45:39,000 --> 00:45:43,100
And why at this time do we so often display juvenile characteristics
587
00:45:43,400 --> 00:45:45,200
such as a need to be spoon-fed?
588
00:45:52,700 --> 00:45:56,400
Parental behavior.
The bond between the human parent and its
589
00:45:56,400 --> 00:45:59,700
young is probably the strongest of any species in the world.
590
00:46:00,100 --> 00:46:02,800
And the effect of being separated can be quite devastating,
591
00:46:02,800 --> 00:46:04,400
especially for the parent.
592
00:46:08,400 --> 00:46:11,700
All is well. All right. All is well.
593
00:46:13,900 --> 00:46:18,300
What is the biological function of rites of passage?
594
00:46:18,300 --> 00:46:20,800
Ceremonies that mark the arrival of sexual maturity.
595
00:46:23,900 --> 00:46:26,700
And why do human individuals remain alive long after they
596
00:46:26,700 --> 00:46:28,500
cease to be able to bear children?
597
00:46:31,600 --> 00:46:32,900
Finally in this series,
598
00:46:33,000 --> 00:46:35,700
I'll be looking at those aspects of our behavior that appear
599
00:46:35,700 --> 00:46:40,300
to have no parallels in the rest of the animal kingdom.
600
00:46:40,300 --> 00:46:43,100
Is the playful behavior of our species really different from
601
00:46:43,100 --> 00:46:44,600
that seen in other animals?
602
00:46:53,200 --> 00:46:56,200
Is body decoration different from the elaborate and colorful
603
00:46:56,200 --> 00:46:58,300
display plumage of birds?
604
00:47:04,500 --> 00:47:07,700
What drives us to take serious risks,
merely for the thrill of it.
605
00:47:12,900 --> 00:47:16,300
But before this, in the next episode, I'll turn my attention
606
00:47:16,400 --> 00:47:19,500
to one of our most fundamental activities.
That of finding food.
607
00:47:22,500 --> 00:47:26,100
There's no other species that consumes such an incredible
608
00:47:26,100 --> 00:47:27,300
variety of food.
609
00:47:28,500 --> 00:47:32,300
In fact we're so good at extracting nutrients
610
00:47:32,300 --> 00:47:35,700
from our environment, that we're able to adapt to, and exploit
611
00:47:35,700 --> 00:47:38,700
virtually every type of habitat on this planet.
612
00:47:50,500 --> 00:47:53,900
And with our modern lifestyle,
what's happened to our ancestral
613
00:47:53,900 --> 00:47:54,900
hunting urges?
614
00:48:00,800 --> 00:48:05,100
Now, I've sometimes been accused of degrading mankind.
615
00:48:05,100 --> 00:48:07,300
Of insulting human dignity
Of making man beastly.
616
00:48:08,400 --> 00:48:11,300
This surprises me because I like animals, and I feel proud
617
00:48:11,300 --> 00:48:13,900
to call myself one.
I've never looked down upon them.
618
00:48:14,400 --> 00:48:17,400
So to call human beings animals is not to me, degrading.
619
00:48:17,800 --> 00:48:21,400
It's simply being honest, and putting us in our place as part
620
00:48:21,400 --> 00:48:24,200
of the scheme of nature on the planet Earth.
