On May 27th, 1941, the German battleship Bismarck sank in a fierce firefight,
0
6664
6480
00:13
leaving only 118 of her 2,200 crew members alive.

00:18
But when a British destroyer came to collect the prisoners,
2
18454
3080
00:21
they found an unexpected survivor -
3
21534
3350
00:24
a black and white cat clinging to a floating plank.
4
24884
3360
00:28
For the next several months this cat hunted rats and raised British morale -
5
28244
4020
00:32
until a sudden torpedo strike shattered the hull and sank the ship.
6
32264

00:36
But, miraculously, not the cat.
7
36264
3380
00:39
Nicknamed Unsinkable Sam,
8
39644
2250
00:41
he rode to Gibraltar with the rescued crew
9
41894
2580
00:44
and served as a ship cat on three more vessels –
10
44474
3140
00:47
one of which also sank - before retiring to the Belfast Home for Sailors.
11

00:53
Many may not think of cats as serviceable sailors,
12
53424
3120
00:56
or cooperative companions of any kind.
13
56544
2780
00:59
But cats have been working alongside humans for thousands of years -
14
59324
3670
01:02
helping us just as often as we help them.
15

01:05
So how did these solitary creatures go from wild predator to naval officer
16
65764
4460
01:10
to sofa sidekick?

The domestication of the modern house cat
18
72874
1700
01:14
can be traced back to more than 10,000 years ago in the Fertile Crescent,
19
74574
3870
01:18
at the start of the Neolithic era.
20
78444
2500
01:20
People were learning to bend nature to their will,
21
80944
2350
01:23
producing much more food than farmers could eat at one time.
22
83294
3190
01:26
These Neolithic farmers stored their excess grain in large pits and short, clay silos.
23
86484
5330
01:31
But these stores of food attracted hordes of rodents,
24
91814
3020
01:34
as well as their predator, Felis silvestris lybica -
25
94834
4090
01:38
the wildcat found across North Africa and Southwest Asia.
26
98924
3700
01:42
These wildcats were fast, fierce, carnivorous hunters.
27
102624
3370
01:45
And they were remarkably similar in size and appearance to today’s domestic cats.
28
105994
4730
01:50
The main differences being that ancient wildcats were more muscular,
29
110724
3500
01:54
had striped coats, and were less social towards other cats and humans.
30
114224
5720
01:59
The abundance of prey in rodent-infested granaries
31
119944
3140
02:03
drew in these typically solitary animals.
32
123084
3090
02:06
And as the wildcats learned to tolerate the presence of humans
33
126174
2605
02:08
and other cats during mealtime,
34
128779
1795
02:10
we think that farmers likewise tolerated the cats in exchange for free pest control.
35
130574
5350
02:15
The relationship was so beneficial that the cats migrated with Neolithic farmers
36
135924
5360
02:21
from Anatolia into Europe and the Mediterranean.
37
141284
3840
02:25
Vermin were a major scourge of the seven seas.
38
145124
2590
02:27
They ate provisions and gnawed at lines of rope,
39
147714
2640
02:30
so cats had long since become essential sailing companions.
40
150354
4110
02:34
Around the same time these Anatolian globe trotting cats set sail,
41
154464
3880
02:38
the Egyptians domesticated their own local cats.
42
158344
3410
02:41
Revered for their ability to dispatch venomous snakes, catch birds, and kill rats,
43
161754
4440
02:46
domestic cats became important to Egyptian religious culture.
44
166194
4700
02:50
They gained immortality in frescos, hieroglyphs, statues, and even tombs,
45
170894
4760
02:55
mummified alongside their owners.
46
175654
3120
02:58
Egyptian ship cats cruised the Nile,
47
178774
2540
03:01
holding poisonous river snakes at bay.
48
181314
3130
03:04
And after graduating to larger vessels,
49
184444
2330
03:06
they too began to migrate from port to port.
50
186774
3880
03:10
During the time of the Roman Empire, ships traveling between India and Egypt
51
190654
4300
03:14
carried the lineage of the central Asian wildcat F. s. ornata.
52
194954
5790
03:20
Centuries later, in the Middle Ages, Egyptian cats voyaged up to the Baltic Sea
53
200744
5030
03:25
on the ships of Viking seafarers.
54
205774
2750
03:28
And both the Near Eastern and North African wildcats
55
208524
3280
03:31
– probably tamed at this point -- continued to travel across Europe,
56
211804
3990
03:35
eventually setting sail for Australia and the Americas.
57
215794
4300
03:40
Today, most house cats have descended
58
220104
2060
03:42
from either the Near Eastern or the Egyptian lineage of F.s.lybica.
59
222164

03:46
But close analysis of the genomes and coat patterns of modern cats
60
226834
3610
03:50
tells us that unlike dogs,
61
230444
2120
03:52
which have undergone centuries of selective breeding,
62
232564
2800
03:55
modern cats are genetically very similar to ancient cats.
63
235364
3760
03:59
And apart from making them more social and docile,
64
239124
2840
04:01
we’ve done little to alter their natural behaviors.
65
241964
3720
04:05
In other words, cats today are more or less as they’ve always been: Wild animals.
66
245684
5710
04:11
Fierce hunters. Creatures that don’t see us as their keepers.
67
251394
3450
04:14
And given our long history together, they might not be wrong.
