All language subtitles for S01E01 - Chimpanzee

The family is one
of the most powerful forces in nature.

Family life is full of wonder...

Beauty...

And drama.

For the past four years,

we've been following some of the most
celebrated and endangered species

on Earth.

We follow their fortunes from here
on the plains of Zimbabwe,

to the jungles of India.

From the edge of the Sahara,

to the frozen wastes of Antarctica.

We join each family
at a crucial moment in their lives

when they're battling against the odds.

Fighting for survival

against the elements,

and against rivals.

We've got closer
and filmed in greater length

and in more detail than
we've ever tried to do before.

In our modern world,

ensuring the survival
of the next generation

is becoming ever more difficult.

For these families,
to win against the odds

will be their greatest challenge.

This is Dynasties.

Senegal, West Africa.

Home to a remarkable troop
of chimpanzees.

It gets so hot and dry here,

it's the very limit
of where they can survive.

This territory is ruled by
one strong and determined leader.

An alpha male known as David.

His rule gets him
the best of everything.

But he can trust no one.

He's surrounded by
rivals prepared to kill him

for his crown.

This is a story of power,

politics,

and the fight for survival.

David's torn ears are testament
to the many battles he's fought

and won to protect his status

and his family.

He has ruled over
his troop for three years.

Leaders here don't usually hold power
for much longer than this

and now as the dry season begins,

David's rivals are gathering again.

Successful alpha males normally
have many allies to support them.

But David is alone.

He has never been more vulnerable.

In the dry season,
these huge mounds of Earth

are magnets
for all 32 chimps in the group.

The mounds are full of food.

Rich in fat and protein...

Termites.

These chimps have learned to use
grass stems as tools

to fish out the insects.

As leader, David gets
his pick of the feeding spots.

But he is wary

as he must feed alongside old enemies.

He has two particularly
ambitious rivals.

David's toes begin to twitch.

A nervous tic he can't conceal.

This is Jumkin

who has long sought the top spot.

And this, Luthor.

A tempestuous younger male...

...with an aggressive streak.

The troop is together
for the first time in months

and jostling for good feeding spots
can easily lead to clashes.

It's vital that David keeps order
and defuses the situation.

All eyes are on him.

His display shows he is in control.

But in chimp society,

strength alone is not enough.

David must be political
to hold on to power.

He needs to make an ally.

This is K.L.

He's strong but grey-bearded
and past the age

where he would challenge
for the role of alpha.

David makes an approach.

Grooming builds bonds of friendship.

Buying support
and giving benefits in return.

You scratch my back
and I'll scratch yours.

Only time will tell
if this new alliance will pay off.

Temperatures soar.

It's already 40 degrees.

The arid land might seem
one giant sand pit

for the infants.

But for the adults,

existing tensions
are starting to surface.

And David has his eye on Jumkin.

Jumkin attacks an elderly female.

It's a display of his aspirations
for power.

David can't tolerate this,

but K.L. steps in.

And gives Jumkin a sharp lesson.

It's swiftly followed by one
from David himself.

With a final huge lunge at his rival,

Jumkin comes crashing down.

Together, David and KL.
are now a force to be reckoned with.

Fires destroy three-quarters
of the group's territory.

Much of their food and shelter has gone.

And with temperatures
continuing to rise,

water is becoming perilously scarce.

The group must stick together
to survive.

Gathering in a dried-out river bed,

they use knowledge passed down
from generation to generation.

A hidden water source

under the parched earth.

For David, there is more
than just drought to worry about.

He can't avoid his rivals.

K.L. is proving to be
a loyal ally to David.

And David is going to need him
more than ever.

By rare coincidence,

three of the seven females
have become sexually receptive,

at the same time.

Their swellings attract the attention
of all the males.

The females will try to mate
with as many males as possible.

David must control them all

to ensure that he is the one who mates.

But some of the troop, like Luthor,
have other ideas.

All the other males
see this could be their chance.

There has never been
a more important moment

for David to assert his power.

He makes the first move.

His rivals respond
with their own display of strength

and start to close ranks.

David and K.L. seem to be outnumbered.

Everything turns to chaos.

At some point during the night
the younger males turned on David.

The females and their infants
come to his side.

To support him and tend his wounds.

They can't stay here.

They and their young need water.

The whole group move on
to the nearest water hole.

Even K.L. has to leave David behind.

It's a six-mile trek
to the next source of water.

David is left for dead.

There is now a power vacuum at the top

and Luthor sees an opportunity.

Creating fear within the group
is one way to become leader.

He tries to intimidate the group.

But a bid for leadership
is never instant.

He'll have to keep this
up for many days.

Friendless and wounded,

David somehow musters the energy

to search for food.

He has to rejoin the group
before he's exiled for good.

But first he must regain strength.

Time is running out.

Remarkably, one week after the attack,

David makes the long journey
to find the group.

Luthor, meanwhile, has ramped up
his bid for leadership.

David has almost made it.

But he's in no fit state to fight.

Luthor spots David's approach.

And readies himself for battle.

David's only chance against Luthor

is to make himself
look as strong as possible.

Intimidated, Luthor has to run.

Without a blow being struck,
David is back.

David is finally reunited
with his comrade K.L.

Grooming each other
reaffirms their bonds of friendship.

For David,
returning is only half the battle.

Exhausted and fragile,

he's only hanging on
to his leadership by a thread.

Luthor appears defeated.

With a submissive gesture,

he seeks forgiveness from David.

But David is unwilling to accept.

Over the following weeks,
Luthor finds himself sidelined.

The other males now gather round David.

And Luthor has no choice
but to step in line.

David has his group
around him once more.

But he doesn't show them
how weakened he really is.

His injuries haven't healed

and the males could turn on him
again at any moment.

For now, he seems
to be fooling them all.

He's buying himself time
to regain his strength,

before another female comes into season,

when he will face
competition once again.

At last, rain filled clouds
bring an end to the drought.

David's territory is transformed.

There is water everywhere,
and a glut of food.

The pressure on the group is lifted.

Everyone can relax a little
after months of hardship.

David's strength
appears to be returning.

His displays in front of the group
become ever more assertive.

But in truth, he remains weaker
than he lets on to the others.

Whenever possible,
he disappears to gather extra food.

He gorges on everything he can find.

Fruit...

Leaves...

Even ants.

He's almost back to full health.

But that alone might still not be
enough for him to hold on to power.

Soon, another female
will be ready to mate.

Last time, one ally
was not enough for David.

He tries a new strategy.

He starts grooming other males.

First one...

Then another.

Slowly over weeks,

he surrounds himself
with a band of allies.

An army of elders.

Experienced fighters,
but too old to steal his crown.

Now he must wait and see
if he's done enough

to prevent a recurrence
of dissent in the ranks.

Sure enough, a female
has come into season.

Her swelling doesn't go unnoticed.

Last time, David was vulnerable.

This time, he has allies...

...prepared to charge ahead
and clear his path.

Displaying his strength
reminds rivals to stay away.

If David has fully secured
his position as alpha,

he will be the one
who mates with the female.

She catches his eye.

With a number of allies
positioned throughout the group,

none of his rivals
dare to challenge him.

This is David's time to mate.

Nine months later,

a new baby boy.

David's reward for maintaining power.

His rule and the future
of his dynasty is secure.

By being alpha, David will have sired
twice as many offspring

as any other member of the group.

And one day, one of his sons

might just have what it takes
to be a future leader.

David has become the most powerful,
longest reigning alpha

this group has ever seen.

But there will always be
another dry season.

And there will always be rivals
waiting for their chance.

The Dynasties crew has spent
two years capturing

the story of these chimpanzees.

This...

...is how every day begins.

Walking over 7,500 miles.

You know it's steep
when the chimp is being careful.

Carrying around 80 kilos each day.

In some of
the hottest temperatures on Earth.

It's got to be 46, 47 degrees right now.

I think it's fair to say,

filming a blazing fire
when it's 40 degrees

wasn't probably my best idea.

This is crazy,

this is the second time we've had
to run away from bees this morning.

I got stung
and as you might be able to tell,

it's swollen up a little bit.

They bite hard.

How stuck is it?

It's pretty stuck.

But the hardest challenge
of all is understanding the complexities

of the lives of these chimps.

This is only possible
thanks to scientists Jill Pruetz

and her team who have been
studying this troop for nearly 20 years.

One of the reasons I think
I like to have people see the chimps

is that it is almost like a soap opera.

It really is this,

this social group that is
not that different from humans

and so you have relationships change
and you have different personalities.

Jill's insights
help the team to get to know

all the different characters
she has given names to over the years.

But right from the start,
one chimp named David

grabs everyone's attention.

We've only been here a few days,

but immediately David stood out.

He's really recognisable.

He's a bit of a game player,
but, also, he's often on his own.

He's very, very charismatic.

He's got a real kind of swagger to him,
reminds me of Marlon Brando.

Just that he's got this real
kind of presence to him.

David's one of my favourite chimps,

so I may be a little biased,
I think he's quite clever.

I think of him as a very
strong-willed chimp,

a very dominant chimp,

and he was very ambitious
when he first became a young adult,

and he rose up the hierarchy
really quickly for his age.

So he became alpha, actually,
when he was a teenager.

He's constantly having to
fend off challenges

from other younger males.

But it just goes to show
it's tough being alpha.

It's tough being at the top.

After following David for so many months,

he seems almost like family to the crew.

So when he's violently attacked,
it's a real shock.

Coming out this morning,
it's sort of heart breaking

to see this...

Chimp that was so powerful
just looking so weak.

Oh, he doesn't look good,
he's covered in flies.

And he's looking really bad actually.

He looks like a frail old man suddenly.

Like he...

Like he's ready to die almost.

The following day,
their concerns deepen.

We arrived at 5:00 this morning.

We've not been able
to find any of the chimps.

So we've got no idea
what condition David's in

and he's in a bad way already.

Need some luck.

Sort of worried
about him in his state.

Um, I just really hope he's okay.

We're still looking.

They check the remote
camera at the water hole

where they hope David
might have gone to drink.

So I've just gone
from the beginning.

And, um, it looks like David
hasn't been to drink here.

Michel has just found some tracks,
how he finds these things I don't know,

but there's a chance we might
catch up with him.

It's a good sign, let's go.

Luckily the tracks
do indeed lead to David.

We've been really worried
with the extent of his injuries.

We didn't know if he was alive
or if he was ever coming back.

He came right back in
and maintained that alpha status.

David has been alpha for almost
double what we've seen with

the other alphas.

He's been challenged a few times
but he's been able to hold on.

We saw him

not only nearly lose his position
in the hierarchy, but we saw him

nearly lose his life.

The injuries he sustained

in the last coup
would've been enough to kill me.

David has been
able to overcome the many challenges

that have come from within.

But there's a greater threat
that he and his group face.

In Senegal right now,
I'd say the main threat to chimpanzees

is the gold rush which just
obliterates huge areas.

Less than a decade ago,
the prices of gold rose

and people have intensified gold mining

and so that really has increased
the number of people here.

Chimps here have lived
alongside people for thousands of years.

David's group has, so far,
adapted to life alongside humans

in a remarkable way.

But with such demand for these minerals

and ever more people searching
for gold in this region,

habitat destruction and poaching
is inevitable.

You know, there's not
that many chimpanzees left.

The West African chimp here in Senegal

and in West Africa, in general, has been
upgraded to critically endangered

because so many have been lost.

In Senegal, the number of
chimpanzees is now just in the hundreds.

In the last 25 years,

80% of Western Chimpanzees
have disappeared.

And in the future, studies like Jill's
will become increasingly important

to help conservationists
and local governments

protect the surviving chimpanzees,

not only in Senegal,
but across the whole of Africa.

Next time,
a dynasty of thousands.

A great march into the frozen wastes

of Antarctica.

To face the coldest
and cruellest winter on Earth.
