What are animals thinking and feeling?

  • 0:01 - 0:05
    Have you ever wondered
    what animals think and feel?
  • 0:05 - 0:07
    Let's start with a question:
  • 0:08 - 0:12
    Does my dog really love me
    or does she just want a treat?
  • 0:13 - 0:18
    Well, it's easy to see
    that our dog really loves us,
  • 0:18 - 0:20
    easy to see, right,
  • 0:20 - 0:24
    what's going on in that fuzzy little head.
  • 0:25 - 0:26
    What is going on?
  • 0:27 - 0:29
    Something's going on.
  • 0:30 - 0:34
    But why is the question always
    do they love us?
  • 0:34 - 0:36
    Why is it always about us?
  • 0:36 - 0:39
    Why are we such narcissists?
  • 0:41 - 0:44
    I found a different question
    to ask animals.
  • 0:46 - 0:47
    Who are you?
  • 0:50 - 0:53
    There are capacities of the human mind
  • 0:53 - 0:58
    that we tend to think are capacities
    only of the human mind.
  • 0:58 - 1:00
    But is that true?
  • 1:00 - 1:04
    What are other beings
    doing with those brains?
  • 1:05 - 1:07
    What are they thinking and feeling?
  • 1:08 - 1:09
    Is there a way to know?
  • 1:09 - 1:11
    I think there is a way in.
  • 1:11 - 1:13
    I think there are several ways in.
  • 1:13 - 1:17
    We can look at evolution,
    we can look at their brains
  • 1:17 - 1:20
    and we can watch what they do.
  • 1:21 - 1:25
    The first thing to remember is:
    our brain is inherited.
  • 1:26 - 1:30
    The first neurons came from jellyfish.
  • 1:30 - 1:33
    Jellyfish gave rise
    to the first chordates.
  • 1:33 - 1:37
    The first chordates gave rise
    to the first vertebrates.
  • 1:37 - 1:40
    The vertebrates came out of the sea,
  • 1:40 - 1:41
    and here we are.
  • 1:43 - 1:48
    But it's still true that a neuron,
    a nerve cell, looks the same
  • 1:48 - 1:52
    in a crayfish, a bird or you.
  • 1:52 - 1:56
    What does that say
    about the minds of crayfish?
  • 1:57 - 1:58
    Can we tell anything about that?
  • 1:58 - 2:02
    Well, it turns out that
    if you give a crayfish
  • 2:03 - 2:05
    a lot of little tiny electric shocks
  • 2:05 - 2:07
    every time it tries
    to come out of its burrow,
  • 2:08 - 2:10
    it will develop anxiety.
  • 2:11 - 2:15
    If you give the crayfish the same drug
  • 2:15 - 2:17
    used to treat anxiety disorder in humans,
  • 2:18 - 2:21
    it relaxes and comes out and explores.
  • 2:22 - 2:25
    How do we show how much
    we care about crayfish anxiety?
  • 2:26 - 2:27
    Mostly, we boil them.
  • 2:27 - 2:29
    (Laughter)
  • 2:30 - 2:36
    Octopuses use tools,
    as well as do most apes
  • 2:36 - 2:38
    and they recognize human faces.
  • 2:39 - 2:44
    How do we celebrate the ape-like
    intelligence of this invertebrate?
  • 2:44 - 2:45
    Mostly boiled.
  • 2:47 - 2:51
    If a grouper chases a fish
    into a crevice in the coral,
  • 2:51 - 2:56
    it will sometimes go to where it knows
    a moray eel is sleeping
  • 2:56 - 3:00
    and it will signal
    to the moray, "Follow me,"
  • 3:00 - 3:02
    and the moray will understand that signal.
  • 3:03 - 3:06
    The moray may go into the crevice
    and get the fish,
  • 3:06 - 3:08
    but the fish may bolt
    and the grouper may get it.
  • 3:09 - 3:15
    This is an ancient partnership that we
    have just recently found out about.
  • 3:15 - 3:18
    How do we celebrate
    that ancient partnership?
  • 3:18 - 3:20
    Mostly fried.
  • 3:21 - 3:25
    A pattern is emerging and it says
    a lot more about us
  • 3:25 - 3:27
    than it does about them.
  • 3:28 - 3:30
    Sea otters use tools
  • 3:30 - 3:33
    and they take time away
    from what they're doing
  • 3:33 - 3:37
    to show their babies what to do,
    which is called teaching.
  • 3:37 - 3:40
    Chimpanzees don't teach.
  • 3:41 - 3:45
    Killer whales teach
    and killer whales share food.
  • 3:47 - 3:49
    When evolution makes something new,
  • 3:49 - 3:53
    it uses the parts it has
    in stock, off the shelf,
  • 3:53 - 3:56
    before it fabricates a new twist.
  • 3:56 - 3:58
    And our brain has come to us
  • 3:58 - 4:02
    through the enormity
    of the deep sweep of time.
  • 4:02 - 4:06
    If you look at the human brain
    compared to a chimpanzee brain,
  • 4:06 - 4:10
    what you see is we have basically
    a very big chimpanzee brain.
  • 4:10 - 4:14
    It's a good thing ours is bigger,
    because we're also really insecure.
  • 4:14 - 4:16
    (Laughter)
  • 4:16 - 4:19
    But, uh oh, there's a dolphin,
  • 4:19 - 4:22
    a bigger brain with more convolutions.
  • 4:23 - 4:25
    OK, maybe you're saying,
    all right, well, we see brains,
  • 4:26 - 4:28
    but what does that
    have to say about minds?
  • 4:28 - 4:32
    Well, we can see the working of the mind
  • 4:32 - 4:34
    in the logic of behaviors.
  • 4:35 - 4:38
    So these elephants, you can see --
  • 4:38 - 4:41
    obviously, they are resting.
  • 4:41 - 4:45
    They have found a patch of shade
    under the palm trees
  • 4:46 - 4:48
    under which to let their babies sleep,
  • 4:48 - 4:51
    while they doze but remain vigilant.
  • 4:51 - 4:54
    We make perfect sense of that image,
  • 4:54 - 4:58
    just as they make perfect sense
    of what they're doing,
  • 4:58 - 5:02
    because under the arc of the same sun
    on the same plains,
  • 5:02 - 5:05
    listening to the howls
    of the same dangers,
  • 5:05 - 5:10
    they became who they are
    and we became who we are.
  • 5:11 - 5:13
    We've been neighbors for a very long time.
  • 5:13 - 5:16
    No one would mistake
    these elephants as being relaxed.
  • 5:16 - 5:19
    They're obviously very
    concerned about something.
  • 5:19 - 5:21
    What are they concerned about?
  • 5:22 - 5:25
    It turns out that if you record
    the voices of tourists
  • 5:25 - 5:30
    and you play that recording
    from a speaker hidden in bushes,
  • 5:30 - 5:34
    elephants will ignore it,
    because tourists never bother elephants.
  • 5:34 - 5:39
    But if you record the voices of herders
  • 5:39 - 5:44
    who carry spears and often hurt elephants
    in confrontations at water holes,
  • 5:44 - 5:49
    the elephants will bunch up
    and run away from the hidden speaker.
  • 5:49 - 5:52
    Not only do elephants know
    that there are humans,
  • 5:52 - 5:55
    they know that there are
    different kinds of humans,
  • 5:55 - 5:58
    and that some are OK
    and some are dangerous.
  • 5:58 - 6:03
    They have been watching us for much longer
    than we have been watching them.
  • 6:03 - 6:06
    They know us better than we know them.
  • 6:06 - 6:09
    We have the same imperatives:
  • 6:09 - 6:14
    take care of our babies,
    find food, try to stay alive.
  • 6:14 - 6:18
    Whether we're outfitted for hiking
    in the hills of Africa
  • 6:18 - 6:23
    or outfitted for diving under the sea,
    we are basically the same.
  • 6:23 - 6:25
    We are kin under the skin.
  • 6:25 - 6:27
    The elephant has the same skeleton,
  • 6:27 - 6:30
    the killer whale has the same skeleton,
  • 6:30 - 6:31
    as do we.
  • 6:34 - 6:36
    We see helping where help is needed.
  • 6:37 - 6:39
    We see curiosity in the young.
  • 6:40 - 6:44
    We see the bonds of family connections.
  • 6:46 - 6:48
    We recognize affection.
  • 6:49 - 6:51
    Courtship is courtship.
  • 6:52 - 6:55
    And then we ask, "Are they conscious?"
  • 6:55 - 6:58
    When you get general anesthesia,
    it makes you unconscious,
  • 6:58 - 7:01
    which means you have
    no sensation of anything.
  • 7:01 - 7:05
    Consciousness is simply
    the thing that feels like something.
  • 7:05 - 7:09
    If you see, if you hear, if you feel,
    if you're aware of anything,
  • 7:09 - 7:13
    you are conscious, and they are conscious.
  • 7:15 - 7:16
    Some people say
  • 7:16 - 7:19
    well, there are certain things
    that make humans humans,
  • 7:19 - 7:21
    and one of those things is empathy.
  • 7:21 - 7:27
    Empathy is the mind's ability
    to match moods with your companions.
  • 7:27 - 7:29
    It's a very useful thing.
  • 7:29 - 7:31
    If your companions start to move quickly,
  • 7:31 - 7:33
    you have to feel like
    you need to hurry up.
  • 7:33 - 7:35
    We're all in a hurry now.
  • 7:35 - 7:39
    The oldest form of empathy
    is contagious fear.
  • 7:39 - 7:42
    If your companions suddenly
    startle and fly away,
  • 7:42 - 7:44
    it does not work very well for you to say,
  • 7:44 - 7:47
    "Jeez, I wonder why everybody just left."
  • 7:47 - 7:48
    (Laughter)
  • 7:51 - 7:55
    Empathy is old, but empathy,
    like everything else in life,
  • 7:55 - 7:59
    comes on a sliding scale
    and has its elaboration.
  • 7:59 - 8:03
    So there's basic empathy:
    you feel sad, it makes me sad.
  • 8:03 - 8:05
    I see you happy, it makes me happy.
  • 8:05 - 8:08
    Then there's something
    that I call sympathy,
  • 8:08 - 8:10
    a little more removed:
  • 8:10 - 8:14
    "I'm sorry to hear that your grandmother
    has just passed away.
  • 8:14 - 8:17
    I don't feel that same grief,
    but I get it; I know what you feel
  • 8:18 - 8:19
    and it concerns me."
  • 8:19 - 8:22
    And then if we're motivated
    to act on sympathy,
  • 8:22 - 8:23
    I call that compassion.
  • 8:24 - 8:28
    Far from being the thing
    that makes us human,
  • 8:28 - 8:31
    human empathy is far from perfect.
  • 8:31 - 8:36
    We round up empathic creatures,
    we kill them and we eat them.
  • 8:36 - 8:39
    Now, maybe you say OK,
    well, those are different species.
  • 8:39 - 8:43
    That's just predation,
    and humans are predators.
  • 8:43 - 8:48
    But we don't treat our own kind
    too well either.
  • 8:49 - 8:52
    People who seem to know
    only one thing about animal behavior
  • 8:52 - 8:56
    know that you must never attribute
    human thoughts and emotions
  • 8:56 - 8:58
    to other species.
  • 8:59 - 9:01
    Well, I think that's silly,
  • 9:01 - 9:05
    because attributing human thoughts
    and emotions to other species
  • 9:05 - 9:09
    is the best first guess about what
    they're doing and how they're feeling,
  • 9:09 - 9:12
    because their brains
    are basically the same as ours.
  • 9:12 - 9:14
    They have the same structures.
  • 9:14 - 9:19
    The same hormones that create
    mood and motivation in us
  • 9:19 - 9:21
    are in those brains as well.
  • 9:23 - 9:28
    It is not scientific to say that they
    are hungry when they're hunting
  • 9:28 - 9:31
    and they're tired when
    their tongues are hanging out,
  • 9:31 - 9:34
    and then say when they're playing
    with their children
  • 9:34 - 9:36
    and acting joyful and happy,
  • 9:36 - 9:41
    we have no idea if they can possibly
    be experiencing anything.
  • 9:41 - 9:43
    That is not scientific.
  • 9:44 - 9:46
    So OK, so a reporter said to me,
  • 9:46 - 9:51
    "Maybe, but how do you really know
    that other animals can think and feel?"
  • 9:51 - 9:54
    And I started to rifle
    through all the hundreds
  • 9:54 - 9:56
    of scientific references
    that I put in my book
  • 9:56 - 10:00
    and I realized that the answer
    was right in the room with me.
  • 10:00 - 10:03
    When my dog gets off the rug
    and comes over to me --
  • 10:03 - 10:05
    not to the couch, to me --
  • 10:05 - 10:09
    and she rolls over on her back
    and exposes her belly,
  • 10:09 - 10:12
    she has had the thought,
    "I would like my belly rubbed.
  • 10:15 - 10:17
    I know that I can go over to Carl,
  • 10:17 - 10:19
    he will understand what I'm asking.
  • 10:20 - 10:23
    I know I can trust him
    because we're family.
  • 10:23 - 10:26
    He'll get the job done
    and it will feel good."
  • 10:26 - 10:28
    (Laughter)
  • 10:28 - 10:31
    She has thought and she has felt,
  • 10:31 - 10:34
    and it's really not
    more complicated than that.
  • 10:34 - 10:39
    But we see other animals
    and we say, "Oh look, killer whales,
  • 10:39 - 10:41
    wolves, elephants:
  • 10:41 - 10:43
    that's not how they see it."
  • 10:44 - 10:48
    That tall-finned male is L41.
  • 10:48 - 10:50
    He's 38 years old.
  • 10:50 - 10:54
    The female right on his left side is L22.
  • 10:54 - 10:55
    She's 44.
  • 10:55 - 10:58
    They've known each other for decades.
  • 10:59 - 11:01
    They know exactly who they are.
  • 11:01 - 11:02
    They know who their friends are.
  • 11:02 - 11:04
    They know who their rivals are.
  • 11:04 - 11:06
    Their life follows the arc of a career.
  • 11:07 - 11:09
    They know where they are all the time.
  • 11:11 - 11:13
    This is an elephant named Philo.
  • 11:14 - 11:15
    He was a young male.
  • 11:16 - 11:17
    This is him four days later.
  • 11:19 - 11:24
    Humans not only can feel grief,
    we create an awful lot of it.
  • 11:27 - 11:29
    We want to carve their teeth.
  • 11:30 - 11:33
    Why can't we wait for them to die?
  • 11:36 - 11:39
    Elephants once ranged from the shores
    of the Mediterranean Sea
  • 11:39 - 11:42
    all the way down to the Cape of Good Hope.
  • 11:42 - 11:45
    In 1980, there were vast
    strongholds of elephant range
  • 11:45 - 11:47
    in Central and Eastern Africa.
  • 11:47 - 11:52
    And now their range is shattered
    into little shards.
  • 11:52 - 11:56
    This is the geography of an animal
    that we are driving to extinction,
  • 11:56 - 12:00
    a fellow being, the most
    magnificent creature on land.
  • 12:01 - 12:05
    Of course, we take much better care
    of our wildlife in the United States.
  • 12:06 - 12:10
    In Yellowstone National Park,
    we killed every single wolf.
  • 12:10 - 12:13
    We killed every single wolf
    south of the Canadian border, actually.
  • 12:13 - 12:18
    But in the park, park rangers
    did that in the 1920s,
  • 12:18 - 12:20
    and then 60 years later
    they had to bring them back,
  • 12:20 - 12:23
    because the elk numbers
    had gotten out of control.
  • 12:25 - 12:26
    And then people came.
  • 12:26 - 12:30
    People came by the thousands
    to see the wolves,
  • 12:30 - 12:33
    the most accessibly
    visible wolves in the world.
  • 12:34 - 12:37
    And I went there and I watched
    this incredible family of wolves.
  • 12:37 - 12:38
    A pack is a family.
  • 12:38 - 12:42
    It has some breeding adults
    and the young of several generations.
  • 12:43 - 12:48
    And I watched the most famous, most stable
    pack in Yellowstone National Park.
  • 12:48 - 12:52
    And then, when they wandered
    just outside the border,
  • 12:52 - 12:54
    two of their adults were killed,
  • 12:54 - 12:56
    including the mother,
  • 12:57 - 12:59
    which we sometimes call the alpha female.
  • 13:00 - 13:04
    The rest of the family immediately
    descended into sibling rivalry.
  • 13:05 - 13:07
    Sisters kicked out other sisters.
  • 13:08 - 13:11
    That one on the left tried for days
    to rejoin her family.
  • 13:11 - 13:14
    They wouldn't let her
    because they were jealous of her.
  • 13:14 - 13:17
    She was getting too much attention
    from two new males,
  • 13:17 - 13:19
    and she was the precocious one.
  • 13:19 - 13:20
    That was too much for them.
  • 13:20 - 13:23
    She wound up wandering
    outside the park and getting shot.
  • 13:24 - 13:28
    The alpha male wound up
    being ejected from his own family.
  • 13:28 - 13:30
    As winter was coming in,
  • 13:30 - 13:34
    he lost his territory,
    his hunting support,
  • 13:34 - 13:37
    the members of his family and his mate.
  • 13:39 - 13:43
    We cause so much pain to them.
  • 13:44 - 13:49
    The mystery is, why don't
    they hurt us more than they do?
  • 13:50 - 13:53
    This whale had just finished eating
    part of a grey whale
  • 13:53 - 13:56
    with his companions
    who had killed that whale.
  • 13:56 - 13:59
    Those people in the boat
    had nothing at all to fear.
  • 14:00 - 14:02
    This whale is T20.
  • 14:02 - 14:07
    He had just finished tearing a seal
    into three pieces with two companions.
  • 14:07 - 14:10
    The seal weighed about as much
    as the people in the boat.
  • 14:10 - 14:11
    They had nothing to fear.
  • 14:12 - 14:14
    They eat seals.
  • 14:15 - 14:16
    Why don't they eat us?
  • 14:19 - 14:23
    Why can we trust them around our toddlers?
  • 14:24 - 14:30
    Why is it that killer whales have returned
    to researchers lost in thick fog
  • 14:30 - 14:34
    and led them miles until the fog parted
  • 14:34 - 14:37
    and the researchers' home
    was right there on the shoreline?
  • 14:37 - 14:39
    And that's happened more than one time.
  • 14:41 - 14:44
    In the Bahamas, there's a woman
    named Denise Herzing,
  • 14:44 - 14:47
    and she studies spotted dolphins
    and they know her.
  • 14:47 - 14:50
    She knows them very well.
    She knows who they all are.
  • 14:50 - 14:52
    They know her.
    They recognize the research boat.
  • 14:52 - 14:54
    When she shows up,
    it's a big happy reunion.
  • 14:54 - 14:58
    Except, one time showed up and they
    didn't want to come near the boat,
  • 14:58 - 15:00
    and that was really strange.
  • 15:00 - 15:02
    And they couldn't figure out
    what was going on
  • 15:02 - 15:03
    until somebody came out on deck
  • 15:03 - 15:06
    and announced that one
    of the people onboard had died
  • 15:06 - 15:08
    during a nap in his bunk.
  • 15:09 - 15:13
    How could dolphins know
    that one of the human hearts
  • 15:13 - 15:14
    had just stopped?
  • 15:15 - 15:17
    Why would they care?
  • 15:17 - 15:19
    And why would it spook them?
  • 15:21 - 15:26
    These mysterious things just hint at
    all of the things that are going on
  • 15:26 - 15:29
    in the minds that are with us on Earth
  • 15:29 - 15:33
    that we almost never think about at all.
  • 15:34 - 15:36
    At an aquarium in South Africa
  • 15:36 - 15:40
    was a little baby bottle-nosed
    dolphin named Dolly.
  • 15:40 - 15:46
    She was nursing, and one day
    a keeper took a cigarette break
  • 15:46 - 15:50
    and he was looking into the window
    into their pool, smoking.
  • 15:50 - 15:53
    Dolly came over and looked at him,
  • 15:53 - 15:57
    went back to her mother,
    nursed for a minute or two,
  • 15:57 - 15:59
    came back to the window,
  • 15:59 - 16:04
    and released a cloud of milk
    that enveloped her head like smoke.
  • 16:04 - 16:07
    Somehow, this baby bottle-nosed dolphin
  • 16:07 - 16:12
    got the idea of using milk
    to represent smoke.
  • 16:12 - 16:16
    When human beings use one thing
    to represent another,
  • 16:16 - 16:18
    we call that art.
  • 16:18 - 16:20
    (Laughter)
  • 16:20 - 16:21
    The things that make us human
  • 16:21 - 16:24
    are not the things
    that we think make us human.
  • 16:25 - 16:27
    What makes us human is that,
  • 16:27 - 16:30
    of all these things that our minds
    and their minds have,
  • 16:30 - 16:33
    we are the most extreme.
  • 16:34 - 16:37
    We are the most compassionate,
  • 16:37 - 16:40
    most violent, most creative
  • 16:40 - 16:44
    and most destructive animal
    that has ever been on this planet,
  • 16:44 - 16:48
    and we are all of those things
    all jumbled up together.
  • 16:49 - 16:54
    But love is not the thing
    that makes us human.
  • 16:54 - 16:57
    It's not special to us.
  • 16:58 - 17:02
    We are not the only ones
    who care about our mates.
  • 17:02 - 17:05
    We are not the only ones
    who care about our children.
  • 17:07 - 17:12
    Albatrosses frequently fly six,
    sometimes ten thousand miles
  • 17:12 - 17:16
    over several weeks to deliver
    one meal, one big meal,
  • 17:16 - 17:18
    to their chick who is waiting for them.
  • 17:19 - 17:23
    They nest on the most remote islands
    in the oceans of the world,
  • 17:23 - 17:26
    and this is what it looks like.
  • 17:27 - 17:32
    Passing life from one generation
    to the next is the chain of being.
  • 17:32 - 17:35
    If that stops, it all goes away.
  • 17:35 - 17:40
    If anything is sacred, that is,
    and into that sacred relationship
  • 17:40 - 17:42
    comes our plastic trash.
  • 17:43 - 17:45
    All of these birds
    have plastic in them now.
  • 17:46 - 17:51
    This is an albatross six months old,
    ready to fledge --
  • 17:51 - 17:55
    died, packed with red cigarette lighters.
  • 17:55 - 17:58
    This is not the relationship
    we are supposed to have
  • 17:58 - 18:00
    with the rest of the world.
  • 18:00 - 18:03
    But we, who have named
    ourselves after our brains,
  • 18:04 - 18:08
    never think about the consequences.
  • 18:09 - 18:12
    When we welcome new
    human life into the world,
  • 18:12 - 18:17
    we welcome our babies
    into the company of other creatures.
  • 18:17 - 18:19
    We paint animals on the walls.
  • 18:19 - 18:21
    We don't paint cell phones.
  • 18:21 - 18:23
    We don't paint work cubicles.
  • 18:23 - 18:27
    We paint animals to show them
    that we are not alone.
  • 18:27 - 18:29
    We have company.
  • 18:31 - 18:35
    And every one of those animals
    in every painting of Noah's ark,
  • 18:35 - 18:40
    deemed worthy of salvation
    is in mortal danger now,
  • 18:40 - 18:42
    and their flood is us.
  • 18:44 - 18:46
    So we started with a question:
  • 18:46 - 18:48
    Do they love us?
  • 18:50 - 18:52
    We're going to ask another question.
  • 18:53 - 18:57
    Are we capable of using what we have
  • 18:58 - 19:02
    to care enough to simply
    let them continue?
  • 19:05 - 19:06
    Thank you very much.
  • 19:06 - 19:12
    (Applause)
