00:00:31,906 --> 00:00:34,701
...they discovered
an advanced chimpanzee society.
8
00:00:47,422 --> 00:00:49,883
Over the decades, that society
9
00:00:50,717 --> 00:00:53,678
grew to become the biggest chimp group
10
00:00:54,220 --> 00:00:55,430
ever known.
11
00:00:56,639 --> 00:00:58,141
They expanded their territory,
12
00:00:59,809 --> 00:01:01,311
dominated the forest,
13
00:01:02,604 --> 00:01:05,148
and built an empire.

[hooting, whooping]
15
00:01:14,032 --> 00:01:16,034

00:01:17,494 --> 00:01:19,913
and the empire divided.

[music darkens]
18
00:01:23,917 --> 00:01:27,921
A small but powerful band of males
broke away to form their own group.
19
00:01:29,881 --> 00:01:30,924
They became...
20
00:01:32,842 --> 00:01:33,968
the westerners.
21
00:01:35,804 --> 00:01:38,223

their rivalry
27
00:01:54,823 --> 00:01:56,116

It's still just a few days
35
00:02:28,940 --> 00:02:30,775
since the central chimps
36
00:02:31,818 --> 00:02:33,194
found Pork Pie dead.

[music intensifies]
38
00:02:40,076 --> 00:02:42,787
It's not known
what chimps understand about death...
39
00:02:45,290 --> 00:02:46,457
or whether they grieve.
40
00:02:51,129 --> 00:02:54,716
But the loss of Pork Pie
has clearly had an impact.

[hoots softly]
42
00:03:01,055 --> 00:03:02,599
For the central chimps,

When she first arrived,
47
00:03:53,024 --> 00:03:55,860
her sister, Nadine, was neglected.

[baby grunting]

and her personality
is beginning to develop...
51
00:04:06,913 --> 00:04:09,249
she's begun to add to Nadine's life.

[loud thrumming of insects]

00:04:43,825 --> 00:04:46,160
Ngogo is never richer in food
58
00:04:46,244 --> 00:04:49,163
than when Chrysophyllum is in fruit.
59
00:04:50,415 --> 00:04:52,333
And it brings the chimps together.

[grunting rhythmically]
61
00:05:19,444 --> 00:05:21,529
Jackson is still under pressure.

Abrams is back in his place,

but he won't give up.
64
00:05:32,623 --> 00:05:35,543
Jackson needs to remind everyone

While Jackson is focused
on dominating at home,

other chimps are standing guard
at the western border...
78
00:06:42,276 --> 00:06:44,153

[music intensifies]
85
00:07:27,447 --> 00:07:29,574

The life of an alpha male isn't easy.
90
00:08:04,567 --> 00:08:06,027
But it comes with benefits.
91
00:08:08,654 --> 00:08:11,240
Generally, the higher a chimp's rank,
92
00:08:12,074 --> 00:08:14,494
the more opportunities they have to mate.
93
00:08:18,789 --> 00:08:20,833
Mature females like Bartoli
94
00:08:22,210 --> 00:08:25,087
normally give birth
every five or six years.

Bartoli's son, Herzog,
is six years old now,

and she's ready to get pregnant again.

[quirky music playing]
101
00:09:28,526 --> 00:09:30,903
She could do a lot worse
than Jackson's genes.
102
00:09:32,822 --> 00:09:34,323
But she needs to be cautious.
103
00:09:38,035 --> 00:09:39,035
Jackson is big,
104
00:09:39,829 --> 00:09:41,998
powerful, and unpredictable.
105
00:09:45,209 --> 00:09:48,296
She needs to keep herself and Herzog safe...
106
00:09:51,299 --> 00:09:53,968
and ensure that Jackson is calm.
107
00:10:05,688 --> 00:10:08,107
Herzog finds the whole thing confusing.
108
00:10:14,614 --> 00:10:15,865
But as a young chimp,
109
00:10:15,948 --> 00:10:17,867
he has to stay close to his mother.
110
00:10:25,291 --> 00:10:26,542
Whatever she's doing.

Jackson is making his move.
115
00:11:00,743 --> 00:11:02,036
By waving a branch,
116
00:11:02,912 --> 00:11:05,665
he's asking Bartoli to follow him...
117
00:11:08,250 --> 00:11:09,250
and mate.
118
00:11:32,066 --> 00:11:33,901
And Bartoli seems keen.
119
00:11:33,984 --> 00:11:34,984

[hooting rhythmically]
124
00:12:19,572 --> 00:12:21,115
Jackson got what he wanted.
125
00:12:26,746 --> 00:12:27,997
And so did Bartoli.
126
00:12:32,960 --> 00:12:34,587
But it's been a tiring day.
127
00:12:40,468 --> 00:12:43,721
Female chimps mate with multiple males.
128
00:12:43,804 --> 00:12:45,222
So there's no guarantee
129
00:12:45,306 --> 00:12:47,933
Jackson will be
the father of Bartoli's baby.
130
00:12:52,271 --> 00:12:54,106
He stands a good chance though.
131
00:12:55,566 --> 00:12:57,109
Because it's happened before.
132
00:12:58,360 --> 00:13:00,154
Although Jackson doesn't know it,
133
00:13:01,697 --> 00:13:03,741
Herzog is his son.

[monkeys croaking rhythmically]

[menacing music playing]
137
00:13:40,694 --> 00:13:43,572
In fact, usually the opposite is true.
138
00:13:46,617 --> 00:13:47,785
They hunt much more
139
00:13:47,868 --> 00:13:50,746
when they are well-fed
and bursting with energy.

or think about the nature
of what they are eating.

[shrieking nearby]
149

[distant shrieking]

For Jackson, this big duiker

00:15:05,779 --> 00:15:08,365
is an opportunity
to strengthen his position

But just as important

is who he's excluding.

[optimistic music playing]

Gus can't offer protection
from a chimp like Wilson.

But at least he can offer some comfort...

But now there's another

[solemn drumbeat reverberates]

Jackson is not with them.
224

As powerful as he is in his own territory,
225
00:24:26,631 --> 00:24:28,967
Jackson fears the west.

[tense music playing]
227
00:24:36,391 --> 00:24:37,726
He grew up in the west
228

and was allies with the westerners
for many years.
229
00:24:45,192 --> 00:24:46,610
But when the group split,
230
00:24:47,486 --> 00:24:48,778
he deserted them
231
00:24:48,862 --> 00:24:52,365
to reign as alpha
of the bigger central group.
232
00:24:57,829 --> 00:24:59,247
As conflict erupted,
233
00:25:00,040 --> 00:25:02,959
the western males targeted Jackson.

But he still bears the scars.
237
00:25:21,645 --> 00:25:25,398
The westerners are a threat
to all the central males.
238

But they hold
a bitter grudge against Jackson.

The westerners are spending
more and more time here feeding.

After killing Pork Pie,
246
00:26:12,487 --> 00:26:14,197
they've grown in confidence.

He's not alpha anymore,
269

but he's still a chimp to be feared.
270
00:29:00,572 --> 00:29:02,282

If they're going to claim

374
00:40:09,448 --> 00:40:10,950
[solemn music playing]
375
00:40:11,033 --> 00:40:12,618
[grunting aggressively]
376
00:40:17,832 --> 00:40:21,669
The western males
are deep inside the central territory.
377
00:40:31,011 --> 00:40:33,639
And they can sense
their enemies are close.
378
00:40:33,722 --> 00:40:36,642
[sniffing]
379
00:40:45,317 --> 00:40:46,694
[music intensifies]
380
00:40:57,788 --> 00:40:58,873
[music abates]
381
00:40:59,498 --> 00:41:01,167
[deep trilling in distance]
382
00:41:11,469 --> 00:41:14,597
The central chimps
have been caught off guard before.
383
00:41:27,401 --> 00:41:28,527
But not this time.
384
00:41:31,780 --> 00:41:33,824
This time, they're ready.
385
00:41:34,575 --> 00:41:36,327
[dramatic music playing]
386
00:41:53,886 --> 00:41:55,346
[music intensifies]
387
00:41:55,971 --> 00:41:57,264
[music fades out]
388
00:42:07,107 --> 00:42:08,692
[whoops, screeches]
389
00:42:09,443 --> 00:42:12,154
[dramatic music rapidly accelerating]
390
00:42:12,238 --> 00:42:14,240
[music climaxes, fades out]
391
00:42:16,116 --> 00:42:17,409
[subdued hooting]
392
00:42:19,578 --> 00:42:23,332
When two big groups come face-to-face,
393
00:42:24,083 --> 00:42:27,294
the outcome is always unpredictable.
394
00:42:30,881 --> 00:42:32,216
[dramatic music playing]
395
00:42:32,299 --> 00:42:33,634
[whooping]
396
00:42:33,717 --> 00:42:35,261
[shrieking]
397
00:42:37,388 --> 00:42:38,847
[music intensifies]
398
00:42:50,776 --> 00:42:52,152
[music intensifies]
399
00:42:57,992 --> 00:42:59,368
The westerners attack.
400
00:43:01,537 --> 00:43:04,540
[screeching, whooping]
401
00:43:06,959 --> 00:43:09,878
And the centrallers meet them head-on.
402
00:43:28,397 --> 00:43:30,149
Bergl is right in the middle of it.
403
00:43:32,693 --> 00:43:34,278
[screeching, whooping continue]
404
00:43:34,361 --> 00:43:35,696
[music intensifies]
405
00:43:42,286 --> 00:43:44,663
The westerners are pushing
the centrallers back.
406
00:43:45,914 --> 00:43:47,374
[frantic shrieking]
407
00:43:54,798 --> 00:43:56,634
- [shrieking stops]
- [music fades out]
408
00:44:06,310 --> 00:44:07,978
[solemn music playing]
409
00:44:14,151 --> 00:44:16,278
[hooting softly]
410
00:44:23,243 --> 00:44:26,789
But some chimps
still haven't joined the battle.
411
00:44:28,499 --> 00:44:29,917
[music intensifies]
412
00:44:36,131 --> 00:44:37,591
[shrieking]
413
00:44:46,475 --> 00:44:48,644
[solemn drumbeat reverberates]
414
00:44:52,189 --> 00:44:54,566
If the centrallers
are going to fight back,
415
00:44:54,650 --> 00:44:57,736
it will be now, behind their alpha.
416
00:44:59,530 --> 00:45:01,865
[drumbeat accelerates]
417
00:45:16,630 --> 00:45:19,174
Jackson is face-to-face
with his old rivals.
418
00:45:20,092 --> 00:45:22,845
The same chimps
that tried to kill him years ago.
419
00:45:22,928 --> 00:45:24,930
- [whooping]
- [shrieking]
420
00:45:27,933 --> 00:45:29,518
[drumbeat intensifies]
421
00:45:34,148 --> 00:45:35,441
[panting rapidly]
422
00:45:44,575 --> 00:45:45,659
[drumbeat ends]
423
00:45:48,871 --> 00:45:50,372
Jackson shows no fear.
424
00:45:50,456 --> 00:45:51,749
[screeching]
425
00:45:51,832 --> 00:45:53,625
[dramatic music playing]
426
00:45:57,129 --> 00:45:59,047
And his group get behind him.
427
00:46:00,924 --> 00:46:02,468
[grunting rhythmically]
428
00:46:02,551 --> 00:46:04,970
[shrieking]
429
00:46:11,310 --> 00:46:12,770
[music intensifies]
430
00:46:18,066 --> 00:46:19,818
[shrieking continues]
431
00:46:24,531 --> 00:46:25,991
[music intensifies]
432
00:46:35,751 --> 00:46:37,586
[frantic shrieking]
433
00:46:39,046 --> 00:46:40,756
[whooping]
434
00:46:54,645 --> 00:46:55,687
[music abates]
435
00:46:59,107 --> 00:47:01,610
The westerners have been pushed back.
436
00:47:02,778 --> 00:47:03,946
And they're retreating.
437
00:47:13,205 --> 00:47:14,414
[hooting softly]
438
00:47:16,250 --> 00:47:18,585
[hooting loudly]
439
00:47:20,838 --> 00:47:22,214
[shrieking]
440
00:47:31,348 --> 00:47:32,558
[birds chirping]
441
00:47:34,059 --> 00:47:35,519
[insects thrumming]
442
00:47:42,734 --> 00:47:45,195
The central chimps
have held off their rivals.
443
00:47:45,279 --> 00:47:46,613
[melancholy music playing]
444
00:47:49,408 --> 00:47:51,535
But Jackson has been injured
in the battle.
445
00:48:05,674 --> 00:48:07,050
[music intensifies]
446
00:48:10,554 --> 00:48:12,139
He defended his territory.
447
00:48:15,726 --> 00:48:16,935
But at what cost?
448
00:48:21,231 --> 00:48:23,233
[pensive music playing]
449
00:48:28,363 --> 00:48:30,741
[melancholic piano music playing]
