00:45:06,621 --> 00:45:08,999
As well as hammers and anvils,
567
00:45:09,082 --> 00:45:11,042
they have invented this.

[screeching]
569
00:45:13,003 --> 00:45:14,004
A pestle.
570
00:45:17,257 --> 00:45:19,468
Used to mash up palm hearts
571
00:45:20,385 --> 00:45:21,636
so they're easier to eat.
572
00:45:24,181 --> 00:45:27,851
A behavior unique to this community.
573
00:45:27,934 --> 00:45:29,978
[uplifting music continues]
574
00:45:32,689 --> 00:45:36,735
They've even learned
to deactivate poachers' snares
575
00:45:36,818 --> 00:45:40,322
that cause so much damage
to other chimp populations.

[uplifting music fades]
577
00:45:43,158 --> 00:45:46,161
Yet despite these great achievements,
578
00:45:46,995 --> 00:45:48,705
they continue to dwindle.
579
00:45:50,248 --> 00:45:53,835
Only seven Bossou chimps now remain.
580
00:45:58,256 --> 00:45:59,132
A youngster.
581
00:45:59,758 --> 00:46:02,093
The only one left in the group.
582
00:46:03,720 --> 00:46:05,263
Desperate for playmates.

[grunts]
584

Pascal Goumi is a local,
585
00:46:19,319 --> 00:46:21,613
but he's not a threat.
586
00:46:26,076 --> 00:46:27,577
As a field researcher,
587
00:46:27,661 --> 00:46:30,789
he's known this chimp since he was born.
588
00:46:34,084 --> 00:46:35,544
It's fair to say
589
00:46:36,127 --> 00:46:37,796
they've become friends.
590
00:46:42,050 --> 00:46:46,179
Friendship is so crucial to ape success,
591
00:46:46,263 --> 00:46:49,850
it can even transcend species boundaries.
592
00:46:56,773 --> 00:46:59,192
But humans
593
00:46:59,276 --> 00:47:01,152
now dominate the planet.
594
00:47:05,907 --> 00:47:09,244
We've left little room
for our fellow apes.
595
00:47:12,873 --> 00:47:16,585
And we've forgotten
that we have a duty of care.
596
00:47:20,881 --> 00:47:21,756
After all,
597
00:47:22,340 --> 00:47:25,051
this is our family too.
