00:45:06,578 --> 00:45:08,956
As well as hammers and anvils,
567
00:45:09,039 --> 00:45:10,999
they have invented this.

[screeching]
569
00:45:12,960 --> 00:45:13,961
A pestle.
570
00:45:17,214 --> 00:45:19,425
Used to mash up palm hearts
571
00:45:20,342 --> 00:45:21,593
so they're easier to eat.
572
00:45:24,138 --> 00:45:27,808
A behavior unique to this community.
573
00:45:27,891 --> 00:45:29,935
[uplifting music continues]
574
00:45:32,646 --> 00:45:36,692
They've even learned
to deactivate poachers' snares
575
00:45:36,775 --> 00:45:40,279
that cause so much damage
to other chimp populations.

[uplifting music fades]
577
00:45:43,115 --> 00:45:46,118
Yet despite these great achievements,
578
00:45:46,952 --> 00:45:48,662
they continue to dwindle.
579
00:45:50,205 --> 00:45:53,792
Only seven Bossou chimps now remain.
580
00:45:58,213 --> 00:45:59,089
A youngster.
581
00:45:59,715 --> 00:46:02,050
The only one left in the group.
582
00:46:03,677 --> 00:46:05,220
Desperate for playmates.

Pascal Goumi is a local,
585
00:46:19,276 --> 00:46:21,570
but he's not a threat.
586
00:46:26,033 --> 00:46:27,534
As a field researcher,
587
00:46:27,618 --> 00:46:30,746
he's known this chimp since he was born.
588
00:46:34,041 --> 00:46:35,501
It's fair to say
589
00:46:36,084 --> 00:46:37,753
they've become friends.
590
00:46:42,007 --> 00:46:46,136
Friendship is so crucial to ape success,
591
00:46:46,220 --> 00:46:49,807
it can even transcend species boundaries.
592
00:46:56,730 --> 00:46:59,149
But humans
593
00:46:59,233 --> 00:47:01,109
now dominate the planet.
594
00:47:05,864 --> 00:47:09,201
We've left little room
for our fellow apes.
595
00:47:12,830 --> 00:47:16,542
And we've forgotten
that we have a duty of care.
596
00:47:20,838 --> 00:47:21,713
After all,
597
00:47:22,297 --> 00:47:25,008
this is our family too.
