看來，人們害怕昆蟲，
比害怕死亡還要厲害。

我頗信，如果把蜘蛛也考慮在内的話，
00:43
the combinations of insects and spiders

蜘蛛兼昆蟲一定越占恐懼榜首無疑。
00:48
Now, I am not one of those people.

2103
不過，我倒不像他們。
00:50
I really love insects.
9
38863
2146
我喜歡昆蟲。
00:53
I think they're interesting and beautiful,
10
41033
4051
我覺得昆蟲有趣、很美、
有時甚至很萌。
00:57
and sometimes even cute.

是什麽原因呢？
01:14
Well, why is that?
17
62661
1701
什麽原因讓人們一再關注昆蟲呢？
01:16
What is that keeps us
coming back to insects?
coming back to insects?
18
64386

01:20
Some of it, of course, is just the sheer
magnitude of almost everything about them.
magnitude of almost everything about them.
19
68055

有些原因來自昆蟲的幾乎每一方面的量度。
01:24
They're more numerous
than any other kind of animal.
than any other kind of animal.
20
72678
2987
這些量度比任何其他動物都大。
我們甚至還不知道究竟有多少種昆蟲，
01:27
We don't even know how many species
of insects there are,
of insects there are,
21
75689
2824
因爲一直都不斷有新發現。
01:30
because new ones
are being discovered all the time.

22
78537

01:33
There are at least a million,
maybe as many as 10 million.

This means that you could have

熊貓小貓的，靠邊站吧。

（笑聲）
01:52
More seriously, insects are essential.
29
100506
3468
更重要的是，昆蟲不可缺。
01:55
We need them.
30
103998
1447
我們很需要牠們。
01:57
It's been estimated
that 1 out of every 3 bites of food

科學家們利用昆蟲得出種種
對事物的根本發現。
對事物的根本發現。
02:04
Scientist use insects to make fundamental
discoveries

33
112972
3227
02:08
about everything from the structure
of our nervous systems

34
116223
2901
從神經系統到基因和DNA是如何工作的等等，
02:11
to how our genes and DNA work.
35
119148
2148
我最喜歡昆蟲的一面是牠們使我們
02:14
But what I love most about insects
36
122388
1878
02:16
is what they can tell us
about our own behavior.
about our own behavior.
37
124290
2781
對自己的行爲有了深刻的理解。
人們做的東西，昆蟲幾乎都做。
02:19
Insects seem like they do
everything that people do.
everything that people do.
38
127539
3057
02:22
They meet, they mate,
they fight, they break up.
they fight, they break up.
39
130620
3539
牠們邂逅、交配、打鬥、分離。
而牠們做的方式也摻有
看來像是愛或恨的東西。
看來像是愛或恨的東西。
02:26
And they do so with what looks
like love or animosity.
like love or animosity.
40
134509
4061
但是，驅動牠們行徑的和
驅動我們行徑的是不同的東西。
驅動我們行徑的是不同的東西。
02:31
But what drives their behaviors is really
different than what drives our own,
different than what drives our own,
41
139665
5211
02:36
and that difference
can be really illuminating.
can be really illuminating.
42
144900
2574
這種不同能顯耀出很多道理。
02:40
There's nowhere where that's more true
43
148234
1867
而最能説明這個問題的
恰恰是我們最感興趣的 ----
恰恰是我們最感興趣的 ----
02:42
than when it comes to one
of our most consuming interests -- sex.
of our most consuming interests -- sex.
44
150125
3561
性！
02:46
Now, I will maintain.
and I think I can defend,
and I think I can defend,
45
154142
2833
我將堅持這樣一種意想不到的説法，
並且不是沒有道理的：
並且不是沒有道理的：
02:48
what may seem like a surprising statement.
46
156999
2401
我認爲昆蟲的性行
比人類的性行有意思多啦。
比人類的性行有意思多啦。
02:52
I think sex in insects is more
interesting than sex in people.
interesting than sex in people.
47
160749
3547
（笑聲）
02:56
(Laughter)
48
164320
1787
能看見的五花八門的品種
就足以讓我們質疑
就足以讓我們質疑
02:58
And the wild variety that we see
49
166131
3139
03:01
makes us challenge
some of our own assumptions
some of our own assumptions
50
169294
2913
一向對何謂雌雄的想當然的想法了。
03:04
about what it means to be male and female.
51
172231
2724
03:07
Of course, to start with,
52
175663
1651
自然，首先地，很多昆蟲
根本無需性行就能繁殖。
根本無需性行就能繁殖。
03:09
a lot of insects don't need
to have sex at all to reproduce.
to have sex at all to reproduce.
53
177338
2957
雌蚜蟲不用交配就能
複製很小很小的自己。
複製很小很小的自己。
03:12
Female aphids can make little, tiny clones
of themselves without ever mating.
of themselves without ever mating.
54
180319
4430
03:17
Virgin birth, right there.
55
185441
1473
處女誕兒，十足無疑地，
就在你家的玫瑰枝上。
就在你家的玫瑰枝上。
03:18
On your rose bushes.
56
186938
1288
03:20
(Laughter)
57
188250
3196
（笑聲）
而那些有交配行爲的呢？
03:23
When they do have sex,
58
191470
1541
03:25
even their sperm is more
interesting than human sperm.
interesting than human sperm.
59
193035
3257
牠們的精子都比人的精子要多姿多彩。
03:28
There are some kinds of fruit flies
60
196316
2375
有種果蠅，其精子比雄蟲自己的身體還要長。
03:30
whose sperm is longer
than the male's own body.
than the male's own body.
61
198715
3477
03:34
And that's important because the males
use their sperm to compete.
use their sperm to compete.
62
202216
4260
關鍵是因為雄蟲要用其精子來競技。
03:38
Now, male insects do compete with weapons,
like the horns on these beetles.
like the horns on these beetles.
63
206873
4187
雄性昆蟲自然有用武器來競鬥的，
例如這些甲殼蟲用雙角。
03:43
But they also compete
after mating with their sperm.
after mating with their sperm.
64
211553
4244
但是也有在交配之後用其精子來競鬥的。
03:48
Dragonflies and damselflies have penises
that look kind of like Swiss Army knives
that look kind of like Swiss Army knives
65
216726
5126
蜻蜓和豆娘蟲的陰莖
跟瑞士小刀一樣，
跟瑞士小刀一樣，
都帶各色配件，能拔鞘而出。
03:53
with all of the attachments pulled out.
66
221876
2093
03:55
(Laughter)
67
223993
1870
牠們用這些攻無不勝的像勺子的器具
03:57
They use these formidable devices
like scoops,
like scoops,
68
225887
4146
能把雌蟲之前與之交配的
雄蟲的精子都刮掉。
雄蟲的精子都刮掉。
04:02
to remove the sperm from previous males
that the female has mated with.
that the female has mated with.
69
230057
4737
（笑聲）
04:06
(Laughter)
70
234818
2067
那麼，從這些我們能學到什麼呢？
04:08
So, what can we learn from this?
71
236909
2697
（笑聲）
04:11
(Laughter)
72
239630
5679
04:17
All right, it is not a lesson in the sense
of us imitating them
of us imitating them
73
245333
5010
倒不是說這裡有什麼我們
應該模仿牠們什麼，
應該模仿牠們什麼，
04:22
or of them setting
an example for us to follow.
an example for us to follow.
74
250367
3524
或者牠們給了個什麼
榜樣我們去跟，
榜樣我們去跟，
04:25
Which, given this,
is probably just as well.
is probably just as well.
75
253915
3326
幸虧也不需要這樣做。
04:29
And also, did I mention sexual cannibalism
is rampant among insects?
is rampant among insects?
76
257265
3574
還有，剛才我提到過
昆蟲當中非常流行性吞噬的嗎？
昆蟲當中非常流行性吞噬的嗎？
04:32
So, no, that's not the point.
77
260863
2328
我只想說，昆蟲在性行方面
04:35
But what I think insects do,
78
263215
1737
04:36
is break a lot of the rules
that we humans have about the sex roles.
that we humans have about the sex roles.
79
264976
5989
打破很多人們自以為是的性別角色的常規。
04:43
So, people have this idea that nature
dictates kind of a 1950s sitcom version
dictates kind of a 1950s sitcom version
80
271319
5529
我們人仍持有想法，仍停留在
50年代的電視喜劇裡看到的、
50年代的電視喜劇裡看到的、
04:48
of what males and females are like.
81
276872
1955
大自然決定男人 / 女人的行為之說。
04:50
So that males are always
supposed to be dominant and aggressive,
supposed to be dominant and aggressive,
82
278851
3153
就是，男人永遠是應該強勢、侵犯的，
而女人永遠是被動、羞答答的。
04:54
and females are passive and coy.
83
282028
1742
04:55
But that's just not the case.
84
283794
1950
但事實並不是這樣的。
04:58
So for example, take katydids,
85
286606
2062
拿螽斯來說吧，
牠們是蟋蟀和蚱蜢同類
牠們是蟋蟀和蚱蜢同類
05:00
which are relatives of crickets
and grasshoppers.
and grasshoppers.
86
288692
2842
其雄蟲對交配物件非常挑剔，
05:03
The males are very picky
about who they mate with,
about who they mate with,
87
291558
3477
05:07
because they not only transfer
sperm during mating,
sperm during mating,
88
295059
3225
原因是，交配時牠們不單是移交精子
05:10
they also give the female
something called a nuptial gift.
something called a nuptial gift.
89
298308
4466
牠們還給雌蟲一種叫聘禮的東西。
05:14
You can see two katydids
mating in these photos.
mating in these photos.
90
302798
3677
這圖上看到的是兩隻螽斯在交配
兩圖上的雄蟲都是右邊那隻，
05:18
In both panels,
the male's the one on the right,
the male's the one on the right,
91
306499
2320
05:20
and that sword-like appendage
is the female's egg-laying organ.
is the female's egg-laying organ.
92
308843
3580
而那劍狀的附肢是雌蟲的產卵器官。
05:25
The white blob is the sperm,
93
313126
2527
白斑是精子，綠斑就是聘禮，
05:27
the green blob is the nuptial gift,
94
315677
3386
那聘禮是雄蟲用自己的身體
做材料產出來的，
做材料產出來的，
05:31
and the male manufactures
this from his own body
this from his own body
95
319087
3366
05:34
and it's extremely costly to produce.
96
322477
2178
成本非常昂貴。
05:36
It can weigh up to a third
of his body mass.
of his body mass.
97
324679
2708
其重量高達雄蟲體重的三分一。
05:39
I will now pause for a moment
and let you think about
and let you think about
98
327985
2534
我且稍息，讓在坐的想想：
如果人類的男性每次性交之前
05:42
what it would be like if human men,
every time they had sex,
every time they had sex,
99
330543
4163
都得先生產一塊 50 、 60 、 70 磅
重的東西，會是什麼情形？
重的東西，會是什麼情形？
05:46
had to produce something
that weighed 50, 60, 70 pounds.
that weighed 50, 60, 70 pounds.
100
334730
6047
05:52
(Laughter)
101
340801
3607
（笑聲）
05:56
Okay, they would not be able
to do that very often.
to do that very often.
102
344432
3239
肯定就是，他們一定不能頻繁性交。
05:59
(Laughter)
103
347695
1497
（笑聲）
06:01
And indeed, neither can the katydids.
104
349216
2401
事實上，螽斯也不行。
因此就意味著，
螽斯雄蟲非常挑剔，
螽斯雄蟲非常挑剔，
06:04
And so what that means
105
352343
1912
06:06
is the katydid males are very choosy
106
354279
3808
06:10
about who they offer
these nuptial gifts to.
these nuptial gifts to.
107
358111
3080
不會隨便把聘禮
送給不經挑剔的雌蟲。
送給不經挑剔的雌蟲。
06:13
Now, the gift is very nutritious,
108
361215
1926
這聘禮是非常營養豐富的，
06:15
and the female eats it
during and after mating.
during and after mating.
109
363165
2694
雌蟲在交配當中和之後都會進食之。
06:17
So, the bigger it is,
the better off the male is,
the better off the male is,
110
365883
2357
因此聘禮越大，雄蟲越佔便宜，
因為這意味著其精子有更多的時間
灌進雌蟲體內，授精給她的卵子。
灌進雌蟲體內，授精給她的卵子。
06:20
because that means more time for his sperm
111
368264
2176
06:22
to drain into her body
and fertilize her eggs.
and fertilize her eggs.
112
370464
2448
然而，這也等於說雄性在交配方面挺被動的。
06:25
But it also means that the males
are very passive about mating,
are very passive about mating,
113
373521
4350
06:29
whereas the females
are extremely aggressive and competitive,
are extremely aggressive and competitive,
114
377895
3525
而雌性則極為先聲奪人、各不相讓。
06:33
in an attempt to get as many of these
nutritious nuptial gifts as they can.
nutritious nuptial gifts as they can.
115
381444
4316
一心就為搞到儘量多的
那些營養豐富的聘禮。
那些營養豐富的聘禮。
這情形和一貫的俗規有出入了。
06:37
So, it's not exactly
a stereotypical set of rules.
a stereotypical set of rules.
116
385784
3795
一個更普遍的現象是，
06:42
Even more generally though,
117
390974
1711
06:44
males are actually not all that important
in the lives of a lot of insects.
in the lives of a lot of insects.
118
392709
5064
雄性在很多昆蟲的生活並不是最重要的。
06:49
In the social insects --
the bees and wasps and ants --
the bees and wasps and ants --
119
397797
4429
在社群類昆蟲裡 --- 蜜蜂、土蜂、螞蟻等
你每天都能見到的那幾種----
06:54
the individuals that you see every day --
120
402250
2595
06:56
the ants going back and forth
to your sugar bowl,
to your sugar bowl,
121
404869
2445
如在你的糖罐進進出出的螞蟻，
花叢中飛來飛去的蜜蜂，
06:59
the honey bees that are flitting
from flower to flower --
from flower to flower --
122
407338
3009
這些全都是雌性的。
07:02
all of those are always female.
123
410371
2299
一千多年來人們都無法
理解這種狀況，
理解這種狀況，
07:05
People have had a hard time getting
their head around that idea for millennia.
their head around that idea for millennia.
124

4576
古代希臘人知道蜜蜂裡
有一綱類，雄峰，比工蜂要大。
有一綱類，雄峰，比工蜂要大。
07:09
The ancient Greeks knew that there was
a class of bees, the drones,
a class of bees, the drones,
125
417900
5098
07:15
that are larger than the workers,
126
423022
2051
雖然希臘人看不慣雄峰的懶散，
07:17
although they disapproved

07:19
because they could see that
the drones just hang around the hive
the drones just hang around the hive
128
427691
3055
牠們總是圍著蜂窩轉，
轉到婚飛為止,
轉到婚飛為止,
07:22
until the mating flight --
129
430770
1525
07:24
they're the males.
130
432319
1219
人家是雄峰嘛，就乾等到婚飛啦，
07:25
They hang around until the mating flight,
131
433562
2019
從來不參與採集花蜜和花粉。
07:27
but they don't participate
in gathering nectar or pollen.
in gathering nectar or pollen.
132
435605
2739
希臘人搞不清楚雄峰的性別，
07:30
The Greeks couldn't figure out
the drones' sex,
the drones' sex,
133
438368
2284
部分原因是給一特點弄糊塗了：
07:32
and part of the confusion was that they
were aware of the stinging ability of bees
were aware of the stinging ability of bees
134
440676
4567
就是，明知蜜蜂有螫針能力,
但又難以相信持有如此武器的
竟然會是雌性的動物。
竟然會是雌性的動物。
07:37
but they found it difficult to believe
135
445267
2857
07:40
that any animals that bore such a weapon
could possibly be a female.
could possibly be a female.
136
448148
3247
07:43
Aristotle tried to get involved as well.
137
451705
3010
亞裏斯多德也摻合上了。
他猜測： "好吧，
如果帶螫針的是雄的..."
如果帶螫針的是雄的..."
07:46
He suggested, "OK, if the stinging
individuals are going to be the males ..."
individuals are going to be the males ..."
138
454739
4588
說到這，他也糊塗了，
07:51
Then he got confused,
because that would have meant
because that would have meant
139
459351
2466
因為照此論下去，那些在蜂群裡
照顧幼蜂的也是雄的啦。
照顧幼蜂的也是雄的啦。
07:53
the males were also taking care
of the young in a colony,
of the young in a colony,
140
461841
2729
07:56
and he seemed to think
that would be completely impossible.
that would be completely impossible.
141
464594
4408
這讓他認為是完全不可能的事。
然後他就下結論說蜜蜂大概是一身兩性的，
08:01
He then concluded that maybe
bees had the organs of both sexes
bees had the organs of both sexes
142
469026
3049
08:04
in the same individual,
143
472099
1151
雖然這說法不盡荒唐，
因為有些動物的確如此。
因為有些動物的確如此。
08:05
which is not that far-fetched,
some animals do that,
some animals do that,
144
473274
2569
但也說明他最後還是沒弄清楚。
08:07
but he never really
did get it figured out.
did get it figured out.
145
475867
2253
08:10
And you know, even today,
my students, for instance,
my students, for instance,
146
478744
3786
即便是現在，
我的學生也是每看到一動物，
包括昆蟲，都謂之為雄的。
包括昆蟲，都謂之為雄的。
08:14
call every animal they see,
including insects, a male.
including insects, a male.
147
482554
4691
當我告訴他們說
那些兇神惡煞的軍蟻，
那些兇神惡煞的軍蟻，
08:19
And when I tell them
that the ferocious army-ant soldiers
that the ferocious army-ant soldiers
148
487585
3536
08:23
with their giant jaws,
used to defend the colony,
used to defend the colony,
149
491145
2933
頭鱷碩大、捍衛蟻群的，
08:26
are all always female,
150
494102
3102
全是雌的，
學生們都半信半疑。
08:29
they seem to not quite believe me.
151
497228
2334
08:31
(Laughter)
152
499586
1145
08:32
And certainly all of the movies --
Antz, Bee Movie --
Antz, Bee Movie --
153
500755
5200
加上所有的電影，
螞蟻電影、蜜蜂電影-----
螞蟻電影、蜜蜂電影-----
裡面的主角都給扮成是雄的。
08:37
portray the main character
in the social insects as being male.
in the social insects as being male.
154
505979
5855
08:44
Well, what difference does this make?
155
512869
1804
這又怎麽樣啦？ 能說明什麼問題呀？
08:46
These are movies. They're fiction.
156
514697
1637
電影嘛，編的而已。
不就是會說人話的動物嘛。
不就是會說人話的動物嘛。
08:48
They have talking animals in them.
157
516358
1622
就算只只都象傑瑞宋飛地
能說會道，有問題嗎？
能說會道，有問題嗎？
08:50
What difference does it make
if they talk like Jerry Seinfeld?
if they talk like Jerry Seinfeld?
158
518004
3680
我認為有問題。
08:53
I think it does matter,
159
521708
2164
而且是個根源非常深的問題，
08:55
and it's a problem that actually
is part of a much deeper one
is part of a much deeper one
160
523896
2864
08:58
that has implications
for medicine and health
for medicine and health
161
526784
4129
是個能影響到我們的醫療、
衛生、生活多方面的問題。
衛生、生活多方面的問題。
09:02
and a lot of other aspects of our lives.
162
530937
2634
09:05
You all know that scientists
use what we call model systems,
use what we call model systems,
163
533595
3493
各位知道科學家都使用規摹系統，
09:09
which are creatures --
white rats or fruit flies --
white rats or fruit flies --
164
537112
3361
裡面的生物 -- 白鼠 / 果蠅等 -- 是相當於
所有其他動物 (包括人) 的替身來的。
所有其他動物 (包括人) 的替身來的。
09:12
that are kind of stand-ins
for all other animals, including people.
for all other animals, including people.
165
540497
4554
09:17
And the idea is
that what's true for a person
that what's true for a person
166
545075
2944
基本的原理是，符合人的道理
也適用於白鼠身上。
也適用於白鼠身上。
09:20
will also be true for the white rat.
167
548043
2411
而大多數時候，結果出來也符合事實。
09:22
And by and large,
that turns out to be the case.
that turns out to be the case.
168
550478
2980
但也有把這個假設用過頭了的時候。
09:25
But you can take the idea
of a model system too far.
of a model system too far.
169
553482
3761
09:29
And what I think we've done,
170
557924
2269
而我認為用過頭了的一點是
09:32
is use males, in any species,
as though they are the model system.
as though they are the model system.
171
560217
5451
我們把雄性，任何物種的雄性，
都當成是規摹系統，
都當成是規摹系統，
09:37
The norm.
172
565692
1223
視雄性為常規，視之為 " 萬事就該如此 " 。
09:38
The way things are supposed to be.
173
566939
2547
09:41
And females as a kind of variant --
174
569510
3049
而雌性呢，則被視為是變異的，特別的，
09:44
something special that you only study
after you get the basics down.
after you get the basics down.
175
572583
3727
你得先把基本規律定了，才以此研究雌性。
09:49
And so, back to the insects.
176
577802
2683
回到昆蟲這話題上。
09:52
I think what that means
177
580509
1348
我認為人們還沒有搞清楚
眼前到底發生了什麼事情。
眼前到底發生了什麼事情。
09:53
is that people just couldn't see
what was in front of them.
what was in front of them.
178
581881
2819
09:56
Because they assumed that the world's
stage was largely occupied by male players
stage was largely occupied by male players
179
584724
6436
人們假定了佔據世界的
大致上全是雄性，
大致上全是雄性，
而雌性的角色只是次要的、跑龍套的而已。
10:03
and females would only have
minor, walk-on roles.
minor, walk-on roles.
180
591184
3852
10:07
But when we do that, we really miss out
on a lot of what nature is like.
on a lot of what nature is like.
181
595626
5439
沿用這種想法的話，
我們會遺漏很多自然界真貌。
我們會遺漏很多自然界真貌。
也會遺漏對自然界、生物 (包括人) 的
如何各異的這方面的認識。
如何各異的這方面的認識。
10:13
And we can also miss out on the way
natural, living things, including people,
natural, living things, including people,
182
601588
6999
10:20
can vary.
183
608611
1390
正因如此，很多醫療研究
用的都是雄性規摹，
用的都是雄性規摹，
10:22
And I think that's why we've used males
as models in a lot of medical research,
as models in a lot of medical research,
184
610025
5075
10:27
something that we know now to be a problem
185
615124
2065
現在知道問題就來了，
10:29
if we want the results to apply
to both men and women.
to both men and women.
186
617213
4397
研究結果沒法同時
既適用於男性，又適用於女性。
既適用於男性，又適用於女性。
我愛昆蟲的最後一點是
很多人會為之驚恐喪膽的。
很多人會為之驚恐喪膽的。
10:34
Well, the last thing
I really love about insects
I really love about insects
187
622760
2527
10:37
is something that a lot of people
find unnerving about them.
find unnerving about them.
188
625311
3261
10:40
They have little, tiny brains
189
628596
1767
就是，牠們腦袋很小，
被普遍覺得認識能力低。
被普遍覺得認識能力低。
10:42
with very little cognitive ability,
the way we normally think of it.
the way we normally think of it.
190
630387
3393
10:46
They have complicated behavior,
but they lack complicated brains.
but they lack complicated brains.
191
634398
4676
牠們行為複雜，卻不具備複雜的腦袋。
因此我們無法當牠們是小人，
10:51
And so, we can't just think of them
as though they're little people
as though they're little people
192
639860
5177
10:57
because they don't do things
the way that we do.
the way that we do.
193
645061
3545
牠們做事方法並不像人一樣的。
11:00
I really love that it's difficult
to anthropomorphize insects,
to anthropomorphize insects,
194
648630
4100
讓我喜歡的一點是，
我們很難把昆蟲擬人化，
我們很難把昆蟲擬人化，
11:04
to look at them and just think of them
like they're little people
like they're little people
195
652754
3523
很難看著牠們，然後把牠們
當作是人的外骨骼，帶六足。
當作是人的外骨骼，帶六足。
11:08
in exoskeletons, with six legs.
196
656301
2138
反而，你得以牠們的本身
固有的面目來看待牠們。
固有的面目來看待牠們。
11:10
(Laughter)
197
658927
1261
11:12
Instead, you really have to accept them
on their own terms,
on their own terms,
198
660212
3545
11:15
because insects make us question
what's normal and what's natural.
what's normal and what's natural.
199
663781
5133
昆蟲讓我們的質疑
什麼是常規、什麼是自然的。
什麼是常規、什麼是自然的。
11:21
Now, you know, people write fiction
and talk about parallel universes.
and talk about parallel universes.
200
669527
4633
各位知道，人們喜歡
編寫故事，談論並存世界。
編寫故事，談論並存世界。
11:26
They speculate about the supernatural,
201
674184
3298
人們揣測超自然的東西，
11:29
maybe the spirits of the departed
walking among us.
walking among us.
202
677506
3433
逝者之靈在我們當中徜徉什麼的。
11:34
The allure of another world
203
682537
3196
異域世界的魅力源自
11:37
is something that people say is part of
why they want to dabble in the paranormal.
why they want to dabble in the paranormal.
204
685757
6154
我們都想
試試非自然到底是怎麽回事。
試試非自然到底是怎麽回事。
11:44
But as far as I'm concerned,
205
692376
2289
而我卻認為，
完全毋需穿視死人的能力，
11:46
who needs to be able to see dead people,
206
694689
2169
11:48
when you can see live insects?
207
696882
1678
能目睹活生生的昆蟲就夠了。
11:51
Thank you.
208
699262
1162
謝謝。

ABOUT THE SPEAKER
Marlene Zuk - Evolutionary biologistMarlene Zuk studies insect behavior -- and how humans use animal behavior to think about how we behave ourselves.
Why you should listen
Marlene Zuk is a biologist and writer who researches animal behavior and evolution, mostly using insects as subjects. Zuk is interested in the ways that people use animal behavior to think about human behavior, and vice versa, as well as in the public's understanding of evolution. She teaches graduate and undergraduate courses in the Department of Ecology, Evolution and Behavior at the University of Minnesota -- including a seminar called “What’s the Alternative to Alternative Medicine?”
In addition to publishing numerous scientific articles, Zuk has published four books for a general audience: Sexual Selections: What We Can and Can’t Learn About Sex from Animals; Riddled with Life: Friendly Worms, Ladybug Sex, and the Parasites That Make Us Who We Are; Sex on Six Legs: Lessons on Life, Love and Language from the Insect World; and most recently, Paleofantasy: What Evolution Really Tells Us About Sex, Diet and the Way We Live.
