-
Not Synced
Well, I have known many
alpha males in my life,
-
Not Synced
chimpanzee alpha males,
-
Not Synced
and I'm going to talk about
what an alpha male is,
-
Not Synced
because I think we can all learn
a lot from our close relatives
-
Not Synced
where we have alpha males.
-
Not Synced
And as an example, I want to give you
Amos, a male that I knew
-
Not Synced
who was a young male
and he was alpha male,
-
Not Synced
he was very popular,
-
Not Synced
but he got sick
-
Not Synced
and he lost his position because,
you know, chimpanzee males
-
Not Synced
they can spot from a mile away
if you are weak
-
Not Synced
and they went for him,
-
Not Synced
and he lost his position,
and then he got sicker and sicker
-
Not Synced
until at some point
-
Not Synced
we had to isolate him.
-
Not Synced
The group lived on a grassy island,
-
Not Synced
and we had to isolate him in a cage,
-
Not Synced
but we cracked open the cage
so that the rest of the chimps
-
Not Synced
still had access to him.
-
Not Synced
And what happened was most touching.
-
Not Synced
Other chimps would bring food to him,
-
Not Synced
they would bring wood wool to him,
-
Not Synced
which is this thing that they use
to sleep in and build nests out of,
-
Not Synced
and females would put
the wood wool behind his back.
-
Not Synced
He was leaning heavily against the wall,
-
Not Synced
and look, the way we do with pillows
and to patients in a hospital,
-
Not Synced
they were putting
that stuff behind his back.
-
Not Synced
And I thought, this is the way
to go for an alpha male.
-
Not Synced
He was loved and respected,
and everyone was taking care of him,
-
Not Synced
and this is not always how it goes,
-
Not Synced
because some males don't answer well
when they lose their position.
-
Not Synced
So Amos was an example
of a male who was liked as a leader,
-
Not Synced
and I think the term alpha male,
-
Not Synced
if you look it up on the internet,
-
Not Synced
you will find all these business books
that tell you how to be an alpha male,
-
Not Synced
and what they mean
is how to beat up others
-
Not Synced
and beat them over the head
and let them know that you are boss
-
Not Synced
and don't mess with me and so on.
-
Not Synced
And basically an alpha male
for them is a bully.
-
Not Synced
And I really don't like
that kind of description,
-
Not Synced
because I am actually partly responsible
for the term "alpha male"
-
Not Synced
because I wrote this book
"Chimpanzee Politics,"
-
Not Synced
which was recommended by Newt Gingrich
-
Not Synced
to freshmen congressmen.
-
Not Synced
I don't know what good it did,
but he recommended that book to them,
-
Not Synced
and after that the term
"alpha male" became very popular.
-
Not Synced
But I think it is used
in a mischaracterization.
-
Not Synced
It's used in a very superficial way
-
Not Synced
that doesn't relate to what
a real alpha male is.
-
Not Synced
And so I'm here to explain what that is.
-
Not Synced
The term itself goes back
Actually much further.
-
Not Synced
It goes back to the '40s and '50s,
research on wolves,
-
Not Synced
and basically the definition
is very simple.
-
Not Synced
The highest ranking male
is the alpha male.
-
Not Synced
The highest ranking female
is the alpha female.
-
Not Synced
Every primate group
has one alpha male, one alpha female,
-
Not Synced
not more than that, there's only one.
-
Not Synced
And I will explain how that goes.
-
Not Synced
So first, the body language.
-
Not Synced
What you see here is two male chimpanzees
-
Not Synced
who are the same size,
-
Not Synced
but one is walking upright,
has his hair up,
-
Not Synced
has a big rock in his hand,
and he's the alpha male.
-
Not Synced
The other male is ?? to him,
-
Not Synced
is being submissive to him
and bowing for him,
-
Not Synced
and that is the sort of ritual they need
to go through many times a day
-
Not Synced
in order to have a stable relationship.
-
Not Synced
I'll show you a video from the field.
-
Not Synced
What you will see here is a female
?? to an alpha male
-
Not Synced
and you will see how that goes.
-
Not Synced
The male is approaching,
-
Not Synced
she grunts at him,
-
Not Synced
he has all his hair up,
-
Not Synced
and he displays.
-
Not Synced
I'm actually standing far too close.
-
Not Synced
A chimpanzee is far stronger than I am,
-
Not Synced
and I just was not very prudent
this particular video.
-
Not Synced
So what you saw him do
-
Not Synced
is he was lifting himself up
and standing on two legs
-
Not Synced
and putting his arms out.
-
Not Synced
That's called the bipedal swagger.
-
Not Synced
It's a very common posture
in high-ranking males,
-
Not Synced
and it's very recognizable
because humans do this kind of stuff.
-
Not Synced
(Laughter)
-
Not Synced
Humans do this all the time.
-
Not Synced
And what I really like
about this particular picture
-
Not Synced
is the two old guys to the side.
-
Not Synced
This is very chimpanzee.
-
Not Synced
In chimpanzees,
-
Not Synced
we have usually old males
who are over the hill
-
Not Synced
who cannot be alpha male
themselves anymore,
-
Not Synced
but they start playing games
and forming coalitions
-
Not Synced
and behind the backs of others,
-
Not Synced
and they become extremely influential,
and you may actually have old males
-
Not Synced
who are more influential
than the alpha male himself.
-
Not Synced
Just as an example,
-
Not Synced
the three males that I
used to work with most
-
Not Synced
at the Dutch Zoo long ago,
there where I worked,
-
Not Synced
and the middle male here
is a 17-year old alpha male.
-
Not Synced
The male who is grooming
on the side is twice as old
-
Not Synced
and this old male has made him the leader.
-
Not Synced
So you can imagine that that old male
has an enormous amount of power,
-
Not Synced
because he has made
the alpha male alpha male.
-
Not Synced
The male on the right
-
Not Synced
is individually the strongest male.
-
Not Synced
In captivity, you can test it out,
-
Not Synced
and you can know that this male
has no trouble with either one.
-
Not Synced
He has only trouble
with the combination of the two.
-
Not Synced
And so the coalition formation
that goes on in chimpanzee society
-
Not Synced
makes it much more complex than you think.
-
Not Synced
It means, for example,
-
Not Synced
that the smallest male in a group
can be the alpha male.
-
Not Synced
You don't need to be
the biggest and strongest male.
-
Not Synced
The smallest male, if he has
the right friends and keeps them happy,
-
Not Synced
or he has female support,
-
Not Synced
he can be the alpha male.
-
Not Synced
So the coalition system
makes everything complex,
-
Not Synced
and I'm always waiting here in the US
-
Not Synced
for the primaries,
the end of the primaries,
-
Not Synced
because that's a moment
where you need to demonstrate unity.
-
Not Synced
Now let me first show you
how the unity is shown in chimpanzees.
-
Not Synced
What you see here is two males on the left
-
Not Synced
who are standing together.
-
Not Synced
You also see the big
canine teeth that they have.
-
Not Synced
And they're standing together and they
demonstrate to the rest of the group,
-
Not Synced
"We are together.
-
Not Synced
We are a unit."
-
Not Synced
The males on the right
are walking together in synchrony.
-
Not Synced
That's another way of demonstrating
that you are together.
-
Not Synced
And so demonstrating unity
is extremely important
-
Not Synced
in a coalition system,
-
Not Synced
and as I said, in the primaries
always I'm waiting for that moment
-
Not Synced
because then you have
two members of the same party
-
Not Synced
who have been fighting with each other,
-
Not Synced
and they need to come
together at some moment.
-
Not Synced
And it leads to very awkward situations.
-
Not Synced
People who don't like each other
need to embrace each other
-
Not Synced
and stand together,
-
Not Synced
and that's absolutely essential
for the unity of the party,
-
Not Synced
and if you don't do that,
the party may fall apart.
-
Not Synced
And so if it doesn't go well,
like in this particular case
-
Not Synced
(Laughter),
-
Not Synced
then the party is in deep doo-doo
-
Not Synced
because they have not demonstrated unity.
-
Not Synced
So that's a very important part
of the coalition system,
-
Not Synced
and that's something that we share
between humans and chimpanzees.
-
Not Synced
Now how do you become an alpha male?
-
Not Synced
First of all, you need to be
impressive and intimidating
-
Not Synced
and demonstrate your vigor on occasion,
-
Not Synced
and show that you are very strong
-
Not Synced
and there's all sorts
of ways of doing that.
-
Not Synced
But other things that you need to do
is you need to be generous.
-
Not Synced
So, for example, males
who go on a campaign
-
Not Synced
to dethrone the leader,
-
Not Synced
which may take two or three months
-
Not Synced
where they're testing
all the coalitions in the group,
-
Not Synced
they also become extremely generous.
-
Not Synced
They share food very easily with everyone.
-
Not Synced
Or they start to tickle
the babies of the females.
-
Not Synced
They're normally, male chimpanzees,
not particularly interested in infants,
-
Not Synced
but when they are campaigning like that,
-
Not Synced
they get very interested in infants
and they tickle them
-
Not Synced
and they try to curry favor
with the females.
-
Not Synced
(Laughter)
-
Not Synced
So in humans, of course,
-
Not Synced
I am always intrigued by these men
who are candidates
-
Not Synced
and hold babies up like this.
-
Not Synced
This is not particularly
something that babies like,
-
Not Synced
but since it is a signal
to the rest of the world,
-
Not Synced
they need to hold them in the air.
-
Not Synced
And I was really intrigued by,
-
Not Synced
when we had a female candidate
in the last election,
-
Not Synced
the way she held babies
was more like this,
-
Not Synced
which is what babies really like.
-
Not Synced
But she of course didn't need
to send the message
-
Not Synced
that she could hold a baby
without dropping it,
-
Not Synced
which was what the man was doing.
-
Not Synced
So this is a very common tactic,
-
Not Synced
and male chimpanzees,
they spend a lot of time
-
Not Synced
currying favor with all sorts of parties
-
Not Synced
when they are campaigning.
-
Not Synced
Now what are the privileges and the costs
-
Not Synced
of being an alpha male?
-
Not Synced
The biggest privilege is female.
-
Not Synced
Food is really irrelevant.
-
Not Synced
Male chimpanzees can go
a week without food
-
Not Synced
if there's a female in estrus
and they're sexually interested in her.
-
Not Synced
Food is secondary to sex,
-
Not Synced
and so the male chimpanzees --
-
Not Synced
and we evolutionary biologists,
of course, we have an explanation for this
-
Not Synced
is that sex leads to reproduction
-
Not Synced
and reproductive success
is the measure of evolution.
-
Not Synced
That's how everything evolves,
-
Not Synced
and so if males can enhance
their reproductive success
-
Not Synced
by being high ranking,
-
Not Synced
you get automatically the ambition
to be high ranking in the males.
-
Not Synced
So that's the privilege.
-
Not Synced
The costs, one cost is of course
-
Not Synced
that you need to keep your partners happy.
-
Not Synced
So if you come to power
with the support of an old male,
-
Not Synced
you need to let that old male
mate with females.
-
Not Synced
If you don't do that, that old male
is going to get mad at you
-
Not Synced
and you're going to lose him as a partner.
-
Not Synced
So there's a transaction going on.
-
Not Synced
If you become alpha male this way,
you need to keep your partners happy.
-
Not Synced
And so that's one of the costs.
-
Not Synced
The second cost is that
everyone wants your position.
-
Not Synced
Alpha male position
is a very important position,
-
Not Synced
and everyone wants to take it from you,
-
Not Synced
and so you constantly
have to watch your back.
-
Not Synced
You have to be extremely vigilant.
-
Not Synced
For example, you have to disrupt
the coalitions of others,
-
Not Synced
and that's what male
chimpanzees do quite a bit.
-
Not Synced
Divide and rule strategies, they have.
-
Not Synced
And so that's a very stressful situation,
and we actually have data on this.
-
Not Synced
The data comes from the field,
-
Not Synced
from baboons not chimpanzees in this case,
-
Not Synced
where they did fecal samples
on the baboons
-
Not Synced
and they analyzed them
for glucocorticoids,
-
Not Synced
and what you see here is a graph
-
Not Synced
where you see that the local ranking
the male baboon is,
-
Not Synced
the higher is his cortisol level
-
Not Synced
in the feces,
-
Not Synced
but the alpha male, as you see,
-
Not Synced
has just as high a level
as the lowest-ranking males,
-
Not Synced
and so you may think that being alpha male
is nice and dandy and is wonderful,
-
Not Synced
but it's actually
a very stressful position,
-
Not Synced
and we can demonstrate
that physiologically.
-
Not Synced
Now, what are the obligations?
-
Not Synced
And here, for me,
it gets really interesting,
-
Not Synced
and it deviates very much from
your typical image of the alpha male.
-
Not Synced
The alpha male
has two sorts of obligations.
-
Not Synced
One is to keep the peace in the group.
-
Not Synced
We call that the control role,
-
Not Synced
to control fights in the group,
-
Not Synced
and the second is to be the most empathic,
-
Not Synced
the consoler in chief, basically,
of the nation, so to speak.
-
Not Synced
So first of all, keeping the peace.
-
Not Synced
This is a male who stops a fight
between two females.
-
Not Synced
Two females on the left and the right
have been screaming and yelling
-
Not Synced
at each other over food,
-
Not Synced
because food is very
important for the females,
-
Not Synced
and so he stops the fight between them
and stands between them like this.
-
Not Synced
And it's very interesting to me
that alpha males, when they do this,
-
Not Synced
they become impartial.
-
Not Synced
They don't support their mom
or their best buddy.
-
Not Synced
No, no, they stop fights
-
Not Synced
and they come up
for the underdog in general.
-
Not Synced
And this makes them extremely
popular in the group,
-
Not Synced
because they provide security for
the lowest-ranking members of the group,
-
Not Synced
and so they become impartial,
-
Not Synced
which is an unusual condition
for a chimpanzee to be in,
-
Not Synced
because they're usually
very fond of their friends and so on,
-
Not Synced
and with alpha males who are good at this,
-
Not Synced
they can be very effective
at keeping the peace in the group.
-
Not Synced
And the second thing they do
is they show empathy for others.
-
Not Synced
Now, I do an enormous amount
of research on empathy,
-
Not Synced
and I don't have time to go into it,
-
Not Synced
but empathy is nowadays a topic
that we study in rodents and dogs
-
Not Synced
and elephants and primates,
-
Not Synced
all sorts of animals.
-
Not Synced
And what you see here is two bonobos.
-
Not Synced
The one in front
-
Not Synced
has been beaten up in a fight.
-
Not Synced
The one in the back puts
her arms around her and consoles her.
-
Not Synced
This is also actually how we measure
empathy in young children,
-
Not Synced
by looking at how they respond
to distressed individuals.
-
Not Synced
And high-ranking males,
they do a lot of this.
-
Not Synced
High-ranking males provide
an enormous amount of comfort in the group
-
Not Synced
and they go to places
where there are earthquakes
-
Not Synced
or hurricanes and they provide comfort.
-
Not Synced
The pope does this.
The presidents do this.
-
Not Synced
All the leaders in the world
have to do this job.
-
Not Synced
The queen does it and so on.
-
Not Synced
They all have to do this job,
-
Not Synced
so providing consolation,
and that's a very important task.
-
Not Synced
And males who are good at these two,
-
Not Synced
keeping the peace and providing comfort,
-
Not Synced
they become extremely popular leaders,
-
Not Synced
and there's actually
some self-interest involved in it.
-
Not Synced
They don't do it just for the group,
-
Not Synced
because it also stabilizes their position.
-
Not Synced
The more popular a male
becomes as alpha male,
-
Not Synced
and the more the rest of them
respects them and looks up to them,
-
Not Synced
the better their position is defended
-
Not Synced
in case it's going to be
challenged by somebody else,
-
Not Synced
because then, of course, the whole group
is going to support that male
-
Not Synced
because they want to keep
a leader who is good for them.
-
Not Synced
So the group is usually very supportive
of males who are good leaders,
-
Not Synced
and it's not supportive at all of bullies,
-
Not Synced
and when bullies lose their position,
-
Not Synced
they made end up in
a very bad situation there.
