ABOUT THE SPEAKER
Roger Hanlon - Marine biologist
As a Senior Scientist at the Marine Biological Laboratory in Woods Hole, Massachusetts, Roger Hanlon delves into the undersea world of chameleon-like, color-changing marine animals -- and the practical applications that will emerge when we crack their secrets.

Why you should listen

According to Roger Hanlon, "The diversity and sophistication of marine animals fascinates me, and my cornerstone passion is animal behavior. I particularly enjoy diving in different ocean habitats and studying animals that change color and pattern -- especially octopus, cuttlefish and squid, but also various coral reef fishes.

"I stumbled on to this journey while casually diving in Panama as a college junior and, decades later, I am still striving to figure out how these magnificent animals do what they do -- and why they do it. I am keenly interested in the 'visual ecology' of rapid adaptive coloration used for both camouflage and communication."

4167
這是個奇怪而美妙的腦,
00:17
one that gives rise上升 to an idea理念
of a kind of alternative替代 intelligence情報
1
5476
5497
這個腦會引發一種
對這星球上有另類智慧的想法。
00:22
on this planet行星.
2
10997
1166
00:24
This is a brain that is formed形成
in a very strange奇怪 body身體,
3
12769
4172
這個腦在一具非常奇怪的身體裡,
00:29
one that has the equivalent當量
of small satellite衛星 brains大腦
4
17894
3943
具有相當於遍佈周身的小型衛星腦。
00:33
distributed分散式 throughout始終 that body身體.
5
21861
2799
00:36
How different不同 is it from the human人的 brain?
6
24684
3078
這與人類的腦有多不同呢?
00:39
Very different不同, so it seems似乎,
7
27786
2144
看起來非常不同,
00:41
so much so that my colleagues同事 and I
are struggling奮鬥的 to understand理解
8
29954
4331
以至於我和同事正努力
去了解這大腦的運作方式。
00:46
how that brain works作品.
9
34309
1369
00:48
But what I can tell you for certain某些
10
36100
2392
但我能肯定
00:50
is that this brain is capable
of some amazing驚人 things.
11
38516
4438
這腦能做出些驚人之舉。
00:55
So, who does this brain belong屬於 to?
12
43435
2940
那麼,這是誰的腦呢?
00:59
Well, join加入 me for a little bit
of diving潛水 into the ocean海洋,
13
47153
3267
好,來和我一起潛入海洋,
01:02
where life began開始,
14
50444
1930
生命開始之地,
01:04
and let's have a look.
15
52398
1707
讓我們來看看。
01:07
You may可能 have seen看到 some of this before,
16
55471
2034
你之前可能已經看過一些,
01:09
but we're behind背後 a coral珊瑚 reef,
and there's this rock out there,
17
57529
3409
但我們在珊瑚礁後面,
那裡有岩石,
01:12
a lot of sand, fishes魚類 swimming游泳的 around ...
18
60962
2542
很多沙子,
魚兒游來游去......
01:15
And all of a sudden突然 this octopus章魚 appears出現,
19
63528
2540
突然間,這隻章魚出現了,
01:18
and now it flashes閃爍 white白色,
20
66092
2498
現在牠一閃而過,
把墨水噴在我的臉上,竄走了。
01:20
inks油墨 in my face面對 and jets噴氣機 away.
21
68614
1722
01:22
In slow motion運動 reverse相反,
22
70360
1229
在慢動作反轉中,
01:23
you see the ring develop發展 around the eye,
23
71613
2062
你會看到環在眼睛周圍形成,
01:25
and then the pattern模式 develops發展 in the skin皮膚.
24
73699
2348
接著圖案在皮膚上形成。
01:28
And now watch the 3-D-D texture質地
of the skin皮膚 change更改
25
76071
3416
現在看皮膚的 3D 紋理變化,
01:31
to really create創建 this
beautiful美麗, 3-D-D camouflage偽裝.
26
79511
3625
真正創造出這種美麗的 3D 迷彩。
01:36
So there are 25 million百萬 color顏色 organs器官
called "chromatophores色度磷" in the skin皮膚,
27
84249
5602
皮膚有 2500 萬個
稱為「色素細胞」的顏色器官,
01:41
and all those bumps顛簸 out there,
which哪一個 we call "papillae帕皮利亞,"
28
89875
2991
這些突起通通被稱為「乳突」,
01:44
and they're all neurallyneurally controlled受控
and can change更改 instantaneously瞬間.
29
92890
3477
全都由神經控制,可以瞬間改變。
01:48
I would argue爭論 that dynamic動態 camouflage偽裝
30
96391
3383
我認為動態偽裝是一種「智慧」。
01:51
is a form形成 of "intelligence情報."
31
99798
2636
01:55
The level水平 of complexity複雜 of the skin皮膚
with fast快速 precision精確 change更改
32
103021
3555
快速和精確變化的皮膚
的確複雜得令人驚訝。
01:58
is really quite相當 astonishing驚人.
33
106600
2082
02:00
So what can you do with this skin皮膚?
34
108706
2580
那麼,這種皮膚能怎麼用?
02:03
Well, let's think a little bit
about other things besides除了 camouflage偽裝
35
111310
3428
好吧,讓我們想想除了偽裝以外
02:06
that they can do with their skin皮膚.
36
114762
1850
牠們的皮膚能怎麼用。
02:08
Here you see the mimic模仿者 octopus章魚
and a pattern模式.
37
116636
2853
在這裡看得到模仿的章魚和圖案,
02:11
All of a sudden突然,
it changes變化 dramatically顯著 --
38
119513
2032
突然間發生巨大的變化——
那是信號,不是偽裝——
02:13
that's signaling發信號, not camouflage偽裝.
39
121569
1625
02:15
And then it goes back
to the normal正常 pattern模式.
40
123218
2198
然後它又回到正常模式。
02:17
Then you see the broadclub寬俱樂部 cuttlefish烏賊
41
125440
2246
接著你看到白斑烏賊
02:19
showing展示 this passing通過 cloud display顯示
as it approaches方法 a crab螃蟹 prey獵物.
42
127710
4479
在接近螃蟹獵物時
顯示浮雲飄過的樣子。
02:24
And finally最後, you see the flamboyant龍飛鳳舞
cuttlefish烏賊 in camouflage偽裝
43
132213
3664
最後,你看到偽裝的烏賊,
02:27
and it can shift轉移 instantly即刻
to this bright warning警告 display顯示.
44
135901
4377
它能立即轉成這明亮的警示。
02:32
What we have here
is a sliding滑動 scale規模 of expression表達,
45
140750
4984
這裡有連續的表達級別,
02:37
a continuum連續, if you will,
46
145758
1611
從顯眼到偽裝,連續著。
02:39
between之間 conspicuousness顯眼 and camouflage偽裝.
47
147393
3067
02:42
And this requires要求 a lot of control控制.
48
150484
2401
這需要很多控制。
02:44
Well, guess猜測 what?
49
152909
1174
猜猜怎麼著?
02:46
Brains are really good for control控制.
50
154107
2604
腦真的很適合控制。
02:48
The brain of the octopus章魚 shown顯示 here
has 35 lobes to the brain,
51
156735
4337
這裡顯示的章魚大腦有 35 個腦裂片,
02:53
80 million百萬 tiny cells細胞.
52
161096
2395
8000 萬個小細胞。
02:55
And even though雖然 that's interesting有趣,
53
163515
2618
即使那很有意思,
02:58
what's really odd is that
the skin皮膚 of this animal動物
54
166157
2300
真正奇怪的是
這種動物的皮膚有更多的神經元,
03:00
has many許多 more neurons神經元, as illustrated插圖
here, especially特別 in the yellow黃色.
55
168481
4247
如圖所示,尤其是黃色的神經元。
03:04
There are 300 million百萬 neurons神經元 in the skin皮膚
56
172752
2984
皮膚中有 3 億個神經元,
03:07
and only 80 million百萬 in the brain itself本身 --
57
175760
2140
而大腦本身只有 8000 萬個,
03:09
four times as many許多.
58
177924
1531
(皮膚擁有的是腦的)4 倍。
03:11
Now, if you look at that,
59
179479
1593
如果你看,
03:13
there's actually其實 one of those
little satellite衛星 brains大腦
60
181096
3857
實際上有個小的衛星腦,
03:16
and the equivalent當量 of the spinal cord
for each of the eight arms武器.
61
184977
3076
和相當於脊髓的八條手臂。
03:20
This is a very unusual異常 way
to construct構造 a nervous緊張 system系統 in a body身體.
62
188077
3715
這種構建體內神經系統的方式
非比尋常。
03:23
Well, what is that brain good for?
63
191816
1918
那這樣的腦有什麼好處呢?
03:25
That brain has to outwit戰勝
other big, smart聰明 brains大腦
64
193758
3637
那腦必須智勝其他
試圖吃掉牠的聰明腦,
03:29
that are trying to eat it,
65
197419
1698
03:31
and that includes包括 porpoises海豚 and seals密封件
66
199141
3065
包括海豚和海豹,
03:34
and barracudas梭魚 and sharks鯊魚
67
202230
1616
梭魚和鯊魚,
03:35
and even us humans人類.
68
203870
1876
甚至包括我們人類。
03:37
So decision-making做決定 is one of the things
that this brain has to do,
69
205770
4788
因此,腦必須做決策,
03:42
and it does a very good job工作 of it.
70
210582
1725
且要做得很好。
03:44
Shown顯示 here, you see this octopus章魚
perambulating穿孔 along沿,
71
212331
3286
這裡顯示這隻巡視的章魚,
03:47
and then it suddenly突然 stops停止
and creates創建 that perfect完善 camouflage偽裝.
72
215641
3847
牠突然停步,造出完美的偽裝。
03:51
And it's really marvelous奇妙,
73
219905
1292
這真是太棒了,
03:53
because when these animals動物
forage飼料 in the wild野生,
74
221221
2786
因為當這些動物在野外覓食時,
03:56
they have to make over a hundred
camouflaging偽裝 decisions決定
75
224031
2946
牠們必須在兩小時的覓食過程中
做出一百多個偽裝決策,
03:59
in a two-hour兩小時 forage飼料,
76
227001
1251
04:00
and they do that twice兩次 a day.
77
228276
1555
每天兩回。
04:01
So, decision-making做決定.
78
229855
1168
決策。
04:03
They're also figuring盤算 out where to go
and how to get back home.
79
231047
3146
牠們還得弄清楚
要去哪裡和如何回家。
04:06
So it's a decision-making做決定 thing.
80
234217
1842
這是決策之事。
04:08
We can test測試 this camouflage偽裝,
81
236083
1508
我們可以測試這種偽裝,
04:09
like that cuttlefish烏賊 you see behind背後 me,
82
237615
2091
就像在我身後看到的烏賊,
04:11
where we pull the rug地毯 out from under it
83
239730
1940
我們從牠身下抽走地毯,
04:13
and give it a checkerboard棋盤,
84
241694
1493
讓牠在棋盤上,
04:15
and it even uses使用 that strange奇怪
visual視覺 information信息
85
243211
2414
牠甚至用那些奇怪的視覺訊息,
04:17
and does its best最好 to match比賽 the pattern模式
with a little ad-libbing廣告libbing.
86
245649
3578
當場盡力匹配棋盤的模樣。
04:21
So other cognitive認知 skills技能
are important重要, too.
87
249563
2950
其他的認知技能也很重要。
04:24
The squids魷魚 have a different不同
kind of smarts智慧, if you will.
88
252537
3654
魷魚有不同的智慧。
04:28
They have an extremely非常 complex複雜,
interesting有趣 sex性別 life.
89
256215
4661
牠們有非常複雜,有趣的性生活。
04:32
They have fighting戰鬥 and flirting調情
and courting求愛 and mate-guarding伴侶保護
90
260900
5099
牠們會戰鬥、調情、
求愛、護衛伴侶,
04:38
and deception騙局.
91
266023
1771
和欺騙。
04:40
Sound聲音 familiar?
92
268131
1403
聽起來有點熟悉吧?
04:41
(Laughter笑聲)
93
269558
1049
(笑聲)
04:42
And it's really quite相當 amazing驚人
94
270631
1520
非常神奇的是
04:44
that these animals動物 have
this kind of intuitive直觀的 ability能力
95
272175
3757
這些動物能夠直覺地
做這些行為。
04:47
to do these behaviors行為.
96
275956
1454
04:49
Here you see a male and a female.
97
277434
1612
在這裡你看到一雄一雌。
04:51
The male, on the left,
has been fighting戰鬥 off other males男性
98
279070
2688
左邊的雄性一直在對抗其他雄性
04:53
to pair with the female,
99
281782
1166
以與雌性配對,
04:54
and now he's showing展示 a dual pattern模式.
100
282972
1740
現在牠呈現出雙重模式:
04:56
He shows節目 courtship求愛 and love on her side,
101
284736
2295
牠在雌魷魚這邊求愛和展現愛意,
04:59
fighting戰鬥 on the other.
102
287055
1671
在另一邊戰鬥。
05:00
Watch him when she shifts轉變 places地方 --
103
288750
2173
看牠在雌性換邊的時候——
05:02
(Laughter笑聲)
104
290947
1033
(笑聲)
05:04
and you see that he has fluidly流體
changed the love-courtship愛求愛 pattern模式
105
292004
3569
你會看到牠已經流暢地
轉變成求愛模式來面對雌魷魚。
05:07
to the side of the female.
106
295597
1554
05:10
So this kind of dual signaling發信號
simultaneously同時
107
298015
2442
因此,這種並行的雙重信號
05:12
with a changing改變 behavioral行為的 context上下文
108
300481
2150
伴隨著不斷變化的行為背景,
05:14
is really extraordinary非凡.
109
302655
1490
真的非比尋常。
05:16
It takes a lot of brain power功率.
110
304169
1630
需要大量的腦力。
05:17
Now, another另一個 way
to look at this is that, hmm,
111
305823
2534
另一種看待這種情況的方式是,
05:20
maybe we have 50 million百萬 years年份
of evidence證據 for the two-faced male.
112
308381
3793
也許我們有了五千萬年的
男性雙面人的證據。
05:24
(Laughter笑聲)
113
312198
4006
(笑聲)
05:29
All right, let's move移動 on.
114
317188
1552
好,讓我們繼續吧。
05:30
(Laughter笑聲)
115
318764
1057
(笑聲)
05:31
An octopus章魚 on a coral珊瑚 reef
has a tough強硬 job工作 in front面前 it
116
319845
2805
珊瑚礁上的一隻章魚
面對一項艱難的工作,
05:34
to go to so many許多 places地方,
remember記得 and find its den巢穴.
117
322674
3696
得要記住牠去過的很多地方,
還要找到牠的巢穴。
05:38
And they do this extremely非常 well.
118
326394
1543
牠們做得非常好。
05:39
They have short-短- and long-term長期 memory記憶,
119
327961
1843
牠們有短期和長期記憶,
05:41
they learn學習 things
in three to five trials試驗 --
120
329828
2092
牠們試個三到五次就能學會——
05:43
it's a good brain.
121
331944
1155
腦很好。
05:45
And the spatial空間的 memory記憶 is unusually異常 good.
122
333123
2881
空間記憶也極好。
05:48
They will even end結束 their forage飼料
and make a beeline直線
123
336028
3632
牠們在覓食結束後
甚至會直奔巢穴。
05:51
all the way back to their den巢穴.
124
339684
1561
05:53
The divers潛水員 watching觀看 them
are completely全然 lost丟失,
125
341269
2290
看著牠們的潛水員完全迷路了,
05:55
but they can get back,
126
343583
1160
但牠們回得來,
05:56
so it's really quite相當 refined精製
memory記憶 capability能力.
127
344767
3562
所以牠們有非常細緻的記憶能力。
06:00
Now, in terms條款 of cognitive認知 skills技能,
128
348353
1635
在認知技能方面,
06:02
look at this sleeping睡眠 behavior行為
in the cuttlefish烏賊.
129
350012
2851
看看烏賊的這種睡眠行為。
06:04
Especially特別 on the right,
you see the eye twitching抽搐.
130
352887
2382
特別是在右邊,
你會看到牠眼睛抽搐。
06:07
This is rapid快速 eye movement運動
kind of dreaming做夢
131
355293
3162
這是做夢般的快速眼球運動,
06:10
that we only thought
mammals哺乳動物 and birds鳥類 did.
132
358479
2172
以前我們以為哺乳動物和鳥類才有。
06:12
And you see the false color顏色
we put in there
133
360675
2066
看我們放在那裡的假色,
06:14
to see the skin皮膚 patterning圖案 flashing閃爍,
134
362765
2399
看到皮膚圖案閃爍,
06:17
and this is what's happening事件 a lot.
135
365188
2314
這常常發生。
06:19
But it's not normal正常 awake甦醒 behaviors行為;
it's all different不同.
136
367526
3404
但這不是一般清醒時的行為,
完全不是。
06:22
Well, dreaming做夢 is when you have
memory記憶 consolidation合併,
137
370954
4101
人類在鞏固記憶時做夢,
06:27
and so this is probably大概
what's happening事件 in the cuttlefish烏賊.
138
375079
3404
烏賊可能就是這樣。
06:30
Now, another另一個 form形成 of memory記憶
that's really unusual異常
139
378507
2351
另一種非比尋常的記憶形式
06:32
is episodic-like偶發性 memory記憶.
140
380882
1739
是情節之類的記憶。
06:34
This is something that humans人類 need
four years年份 of brain development發展 to do
141
382645
4882
人類需要四年的大腦發育
06:39
to remember記得 what happened發生
during a particular特定 event事件,
142
387551
2983
才記得住特定事件、
06:42
where it happened發生 and when it happened發生.
143
390558
2427
發生的時間和地點。
06:45
The "when" part部分 is particularly尤其 difficult,
144
393009
3080
特別難以記住「何時」這部分,
06:49
and these children孩子 can do that.
145
397120
2495
這些孩子能記住。
06:51
But guess猜測 what?
146
399639
1171
但猜猜怎麼了?
06:52
We find recently最近 that the wily詭計多端的 cuttlefish烏賊
also has this ability能力,
147
400834
4177
我們最近發現狡猾的烏賊
也具有這種能力。
06:57
and in experiments實驗 last summer夏季,
148
405035
1840
在去年夏天的實驗中,
06:58
when you present當下 a cuttlefish烏賊
with different不同 foods食品 at different不同 times,
149
406899
6185
如果在不同的時間餵不同食物給烏賊,
07:05
they have to match比賽 that
with where it was exactly究竟
150
413108
4417
牠們必須確切地匹配位置
07:09
and when was the last time they saw it.
151
417549
3122
以及上一次看到那種食物的時間。
07:12
Then they have to guide指南 their foraging覓食
to the rate of replenishment補水
152
420695
4448
然後,牠們的覓食必須配合地點
07:17
of each food餐飲 type類型 in a different不同 place地點.
153
425167
2207
和每種食物類型的補充速度。
07:19
Sound聲音 complicated複雜?
154
427920
1418
聽起來複雜嗎?
07:21
It's so complicated複雜, I hardly幾乎不
understood了解 the experiment實驗.
155
429362
2912
這太複雜了,我幾乎
無法理解這個實驗。
07:24
So this is really high-level高水平
cognitive認知 processing處理.
156
432298
3573
所以這真的是高級的認知處理。
07:28
Now, speaking請講 of brains大腦
and evolution演化 at the moment時刻,
157
436927
3675
現在談到大腦和進化,
07:32
you look on the right, there's the pathway
of vertebrate脊椎動物 brain evolution演化,
158
440626
3863
右邊有脊椎動物大腦進化的途徑,
07:36
and we all have good brains大腦.
159
444513
1372
我們都有良好的大腦。
07:37
I think everyone大家 will acknowledge確認 that.
160
445909
1921
我想每個人都認可這一點。
07:39
But if you look on the left side,
161
447854
1597
左側描述一些
07:41
some of the evolutionary發展的 pathway
outlined概述 here to the octopus章魚,
162
449475
4413
進化到章魚的途徑。
07:45
they have both converged融合, if you will,
to complex複雜 behaviors行為
163
453912
4353
兩者都匯合到複雜的行為
07:50
and some form形成 of intelligence情報.
164
458289
2186
和某種形式的智慧。
07:52
The last common共同 denominator分母
in these two lines
165
460499
3535
這兩行中的最後一個共同點
07:56
was 600 million百萬 years年份 ago,
166
464058
2022
是 6 億年前
07:58
and it was a worm with very few少數 neurons神經元,
167
466104
2353
一種神經元非常少的蠕蟲。
08:00
so very divergent發散 paths路徑
168
468481
2075
所以,非常不同的路徑
08:02
but convergence收斂 of complicated複雜 behavior行為.
169
470580
2835
匯合到複雜的行為。
08:05
Here is the fundamental基本的 question:
170
473910
2597
這裡有一個很基本的問題:
08:08
Is the brain structure結構體 of an octopus章魚
171
476531
3166
章魚的腦結構
08:11
basically基本上 different不同
down to the tiniest最小的 level水平
172
479721
2618
是否基本上與脊椎動物的不同?
08:14
from the vertebrate脊椎動物 line?
173
482363
1857
08:16
Now, we don't know the answer回答,
174
484244
2028
我們現在沒有答案,
08:18
but if it turns out to be yes,
175
486296
2474
但如果結果是肯定的,
08:20
then we have a different不同
evolutionary發展的 pathway
176
488794
2842
那麼就有不同的進化途徑
08:23
to create創建 intelligence情報 on planet行星 Earth地球,
177
491660
2732
創造出地球上的智慧。
08:26
and one might威力 think that
the artificial人造 intelligence情報 community社區
178
494416
2932
可能那些做人工智慧的人
08:29
might威力 be interested有興趣 in those mechanisms機制.
179
497372
2528
會對這些機制感興趣。
08:32
Well, let's talk genetics遺傳學
just for a moment時刻.
180
500736
3078
好,我們來談點遺傳學。
08:35
We have genomes基因組, we have DNA脫氧核糖核酸,
181
503838
2895
我們有基因組,有 DNA,
08:38
DNA脫氧核糖核酸 is transcripted轉錄 into RNARNA,
182
506757
2176
DNA 被轉錄成 RNA,
08:40
RNARNA translates轉換 that into a protein蛋白,
and that's how we come to be.
183
508957
4271
RNA 將其轉化為蛋白質,
就成了我們。
08:45
Well, the cephalopods頭足類動物 do it differently不同.
184
513252
2319
而頭足類動物有所不同。
08:47
They have big genomes基因組, they have DNA脫氧核糖核酸,
185
515595
3212
牠們有很大的基因組,有 DNA,
08:50
they transcript抄本 it into RNARNA,
186
518831
1944
轉錄成 RNA,
08:52
but now something
dramatically顯著 different不同 happens發生.
187
520799
2508
但發生了一些截然不同的事情。
08:55
They edit編輯 that RNARNA
at an astronomical天文 weird奇怪的 rate,
188
523331
3104
牠們以天文奇速編輯 RNA,
08:58
a hundredfold百倍 more than
we as humans人類 or other animals動物 do.
189
526459
4116
速度超過人類或其他動物數百倍。
09:02
And it produces產生 scores分數 of proteins蛋白質.
190
530599
3134
產生了大量的蛋白質,
09:05
And guess猜測 where most of them are for?
191
533757
2346
猜猜大部分在哪裡?
09:08
The nervous緊張 system系統.
192
536127
1338
在神經系統裡。
09:09
So perhaps也許 this is an unorthodox非正統的 way
193
537489
3260
因此,這可能是動物進化
09:12
for an animal動物 to evolve發展
behavioral行為的 plasticity可塑性.
194
540773
3764
可塑性行為的非正統方式。
09:16
This is a lot of conjecture推測,
but it's food餐飲 for thought.
195
544854
3042
這裡有很多猜測值得去深思。
09:20
Now, I'd like to share分享
with you for a moment時刻
196
548601
2524
現在讓我稍稍分享經驗,
09:23
my experience經驗, and using運用 my smarts智慧
and that of my colleagues同事,
197
551149
4825
並利用我和同事的聰明才智
09:27
to try and get this kind of information信息.
198
555998
1996
嘗試獲取此類訊息。
09:30
We're diving潛水, we can't stay
underwater水下 forever永遠
199
558018
2169
我們潛水,但無法一直待在水下,
09:32
because we can't breathe呼吸 it,
200
560211
1348
因為我們無法呼吸,
09:33
so we have to be efficient高效 in what we do.
201
561583
1978
所以我們必須高效地工作。
09:35
The total sensory感覺的 immersion浸沒
into that world世界
202
563585
2315
把感官全沉浸在水世界中
09:37
is what helps幫助 us understand理解
what these animals動物 are really doing,
203
565924
3494
有助於我們了解
這些動物真正在做什麼。
09:41
and I have to tell you that
it's really an amazing驚人 experience經驗
204
569759
4579
我必須說
在水裡與章魚和潛水員交流
09:46
to be down there and having
this communication通訊
205
574362
3253
真的是一種非常棒的體驗,
09:49
with an octopus章魚 and a diver潛水員
206
577639
1899
09:51
when you really begin開始 to understand理解
that this is a thinking思維, cogitating齒輪,
207
579562
4497
得以藉此明白
牠們是思考和好奇的動物。
09:56
curious好奇 animal動物.
208
584083
1454
09:57
And this is the kind of thing
that really inspires激勵 me endlessly不休.
209
585939
3355
這真的無止盡地激勵著我。
10:01
Let's go back to that smart聰明 skin皮膚
for a few少數 moments瞬間.
210
589318
2451
讓我們回到那聰明皮膚片刻。
10:03
Here's這裡的 a squid烏賊 and a camouflage偽裝 pattern模式.
211
591793
2815
這是一隻魷魚和迷彩圖案。
10:06
We zoom放大 down and we see
there's beautiful美麗 pigments顏料 and reflectors反射器.
212
594632
3229
我們放大,看到美麗的顏料和反射層。
10:09
There are the chromatophores色度磷
opening開盤 and closing關閉 very quickly很快.
213
597885
3199
有快速打開和關閉的色素細胞。
10:13
And then, in the next下一個 layer of skin皮膚,
214
601108
2248
接著在下一層皮膚中,
10:15
it's quite相當 interesting有趣.
215
603380
1220
非常有趣。
10:16
The chromatophores色度磷 are closed關閉,
216
604624
1479
色素細胞是封閉的,
10:18
and you see this magical神奇 iridescence彩虹
just come out of the skin皮膚.
217
606127
4132
你會看到皮膚呈現出這種神奇的虹彩。
10:22
This is also neurallyneurally controlled受控,
218
610283
2079
這也是神經控制的,
10:24
so it's the combination組合 of the two,
219
612386
1971
所以是結合兩者,
10:26
as seen看到 here in the high-resolution高分辨率
skin皮膚 of the cuttlefish烏賊,
220
614381
3586
如高解析度的烏賊皮膚中所見,
10:29
where you get this beautiful美麗
pigmentary色素 structural結構 coloration著色
221
617991
4062
這裡有美麗的顏料結構色彩,
10:34
and even the faint blushing臉紅
that is so beautiful美麗.
222
622077
3419
甚至是如此美麗的微紅。
10:38
Well, how can we make use
of some of this information信息?
223
626211
3996
那麼,我們如何利用這些訊息呢?
10:42
I talked about those
skin皮膚 bumps顛簸, the papillae帕皮利亞.
224
630231
2179
我先前談到了皮膚腫塊,即乳突。
10:44
Here's這裡的 the giant巨人 Australian澳大利亞 cuttlefish烏賊.
225
632434
2058
這是巨大的澳大利亞烏賊。
10:46
It's got smooth光滑 skin皮膚
and a conspicuous顯著 pattern模式.
226
634516
2734
牠有光滑的皮膚和明顯的圖案。
10:49
I took five pictures圖片 in a row
one second第二 apart距離,
227
637274
2677
我一秒連拍了五張照片,
10:51
and just watch this animal動物 morph變形 --
one, two, three, four, five --
228
639975
6044
只為看這種動物變形——
一、二、三、四、五——
10:58
and now I'm a seaweed海草.
229
646043
1491
現在牠模仿海藻。
10:59
And then we can come right back out of it
230
647558
1984
倒回來看看
11:01
to see the smooth光滑 skin皮膚
and the conspicuousness顯眼.
231
649566
3065
光滑顯眼的皮膚。
11:04
So this is really
marvelous奇妙, morphing變形 skin皮膚.
232
652655
2801
這真是奇妙變形的皮膚。
11:07
You can see it in more detail詳情 here.
233
655480
2167
在這裡能看得更仔細。
11:09
Periscope潛望鏡 up,
234
657671
1188
潛望鏡升起來了,
11:10
and you've got those beautiful美麗 papillae帕皮利亞.
235
658883
2182
有美麗的乳突。
11:13
And then we look in a little more detail詳情,
236
661089
2175
再看一點細節,
11:15
you can see the individual個人
papillae帕皮利亞 come up,
237
663288
2489
看的到個別的乳突出現,
11:17
and there are little ridges on there,
238
665801
1783
那裡有小脊,
11:19
so it's a papilla乳頭 on papilla乳頭 and so forth向前.
239
667608
2249
是乳突上的乳突等等。
11:21
Every一切 individual個人 species種類 out there
has more than a dozen shapes形狀 and sizes大小
240
669881
4652
每個物種都有十幾種
形狀和大小的凸起,
11:26
of those bumps顛簸
241
674557
1153
11:27
to create創建 fine-tuned微調,
neurallyneurally controlled受控 camouflage偽裝.
242
675734
4071
以創造微調、神經控制的偽裝。
11:32
So now, my colleagues同事
at Cornell康奈爾, engineers工程師,
243
680317
5932
現在我康奈爾大學的同事、工程師們
11:38
watched看著 our work and said,
"We think we can make some of those."
244
686273
3064
看到這些成果,說:
「我們應該能做出一些這種東西。」
11:41
Because in industry行業 and society社會,
245
689361
1598
因為在工業和社會中,
11:42
this kind of soft柔軟的 materials物料
under control控制 of shape形狀
246
690983
2459
這種受形狀控制的軟質材料
11:45
are really very rare罕見.
247
693466
1391
確實非常罕見。
11:46
And they went ahead, worked工作 with us
248
694881
2080
他們開始與我們合作,
11:48
and made製作 the first samples樣本
of artificial人造 papillae帕皮利亞, soft柔軟的 materials物料,
249
696985
3948
製作了人造乳膠,
軟材料的第一批樣品,
11:52
shown顯示 here.
250
700957
1163
如圖所示。
11:54
And you see them blown up
into different不同 shapes形狀,
251
702144
2536
看它們脹成不同的形狀,
11:56
And then you can press your finger手指 on them
252
704704
2023
可以用手指按壓,
11:58
to see that they're
a little bit malleable可鍛鑄 as they are.
253
706751
2785
看得出來它們有點可塑性。
12:01
And so this is an example
of how that might威力 work.
254
709560
3213
這是一個可以拿來運用的例子。
12:04
Well, I want to segueSEGUE from this
into the color顏色 of fabrics面料,
255
712797
4763
好,我想轉談布料的顏色,
12:09
and I imagine想像 that could have
a lot of applications應用 as well.
256
717584
3286
這裡也能有很多應用。
12:12
Just look at this kaleidoscope萬花筒 of color顏色
257
720894

只要看看我們在頭足類動物中看到的
12:15
of dynamically動態 controlled受控

258
723513
2418
動態控制顏料和反射層
如萬花筒般的顏色。
12:17
that we see in the cephalopods頭足類動物.
259
725955
2335
12:20
We know enough足夠 about
the mechanics機械學 of how they work
260
728314
3678
我們對牠們的作用機制了解得夠多,
12:24
that we can begin開始 to translate翻譯 this
261
732016
2133
不僅可以將其轉化為布匹的染料,
12:26
not only into fabrics面料
262
734173
1493
12:27
but perhaps也許 even
into changeable多變 cosmetics化妝品.
263
735690
3526
甚至可以轉化為千變萬化的化妝品。
12:31
And moreover此外, there's been
the recent最近 discovery發現
264
739240
2970
此外,最近在章魚的皮膚中
發現了感光分子,
12:34
of light-sensing光感測 molecules分子
in the skin皮膚 of octopus章魚
265
742234
3511
12:37
which哪一個 may可能 pave鋪平 the way
to, eventually終於, smart聰明 materials物料
266
745769

最終可能會為
能夠自我感知和回應的智慧材料
12:41
that sense and respond響應 on their own擁有.
267
749363
4029
鋪平前路。
12:46
Well, this form形成 of biotechnology生物技術,
or biomimicry仿生學, if you will,
268
754030
5486
那麼,這種形式的生物技術或仿生學
12:51
could change更改 the way we look
at the world世界 even above以上 water.
269
759540
2959
能改變我們看世界的方式,
即使在水面之上亦然。
12:54
Take, for example, artificial人造 intelligence情報
270
762523
2690
例如,人工智慧
12:57
that might威力 be inspired啟發
by the body-distributed身體分佈 brain

能受到章魚周身遍佈腦的啟發,
13:01
and behavior行為 of the octopus章魚

13:03
or the smart聰明 skin皮膚 of a cuttlefish烏賊
273
771096
2292
或烏賊的聰明皮膚的啟發,
13:05
translated翻譯 into cutting-edge前沿 fashion時尚.
274
773412
3581
轉化為尖端時尚。
那麼,
我們如何辦到呢?
13:12
Well, how do we get there?
275
780003
1871
13:13
Maybe all we have to do
276
781898
1975
也許我們只需更聰明地看待
13:15
is to begin開始 to be a little bit smarter聰明
277
783897
3085
頭足類動物是多麼的機靈。
13:19
about how smart聰明 the cephalopods頭足類動物 are.

ABOUT THE SPEAKER
Roger Hanlon - Marine biologist
As a Senior Scientist at the Marine Biological Laboratory in Woods Hole, Massachusetts, Roger Hanlon delves into the undersea world of chameleon-like, color-changing marine animals -- and the practical applications that will emerge when we crack their secrets.

Why you should listen

According to Roger Hanlon, "The diversity and sophistication of marine animals fascinates me, and my cornerstone passion is animal behavior. I particularly enjoy diving in different ocean habitats and studying animals that change color and pattern -- especially octopus, cuttlefish and squid, but also various coral reef fishes.

"I stumbled on to this journey while casually diving in Panama as a college junior and, decades later, I am still striving to figure out how these magnificent animals do what they do -- and why they do it. I am keenly interested in the 'visual ecology' of rapid adaptive coloration used for both camouflage and communication."
