The family structure of elephants - Caitlin O'Connell-Rodwell

  • 0:06 - 0:09
    If I were to distill the 20 years of elephant research
  • 0:09 - 0:11
    that I've done
  • 0:11 - 0:13
    into one sentence,
  • 0:13 - 0:14
    what would it be?
  • 0:14 - 0:16
    What could I tell you?
  • 0:16 - 0:20
    I would say that elephants are just like us!
  • 0:20 - 0:21
    And what do I mean by that?
  • 0:21 - 0:23
    It takes a lot of patience
  • 0:23 - 0:25
    to be out there in the field
  • 0:25 - 0:26
    and trying to figure out patterns
  • 0:26 - 0:29
    of these very slow and intelligent animals.
  • 0:29 - 0:33
    But over time, it is true they are very similar to us.
  • 0:33 - 0:35
    And you think, "Well, how can I say that?
  • 0:35 - 0:37
    Look, they have huge ears,
  • 0:37 - 0:39
    they have really long noses.
  • 0:39 - 0:40
    What do you mean they're like us?"
  • 0:40 - 0:44
    Well, in fact, their families are very similar to ours.
  • 0:44 - 0:48
    And family is extremely important to elephants.
  • 0:48 - 0:51
    They grow up in very tight-knit families
  • 0:51 - 0:53
    and they have extended families.
  • 0:53 - 0:55
    And it's just like our family reunions
  • 0:55 - 0:57
    where you have all the aunts gathering around
  • 0:57 - 0:59
    with all the food they're going to bring and plan,
  • 0:59 - 1:00
    and all the boys are thinking,
  • 1:00 - 1:02
    "Are we going to play our video games together?
  • 1:02 - 1:04
    Are we going to spar?"
  • 1:04 - 1:06
    It's very, very similar,
  • 1:06 - 1:10
    and it's jubilant, and screaming, yelling, it's really amazing to see.
  • 1:10 - 1:13
    But, as soon as you get that family gathering,
  • 1:13 - 1:15
    it's just like a wedding or anything else,
  • 1:15 - 1:17
    all of the sudden the family politics come out,
  • 1:17 - 1:20
    and the lower-ranking individuals in this scene,
  • 1:20 - 1:22
    you see the arrow off to the back,
  • 1:22 - 1:25
    the lower-ranking individuals already know their station,
  • 1:25 - 1:27
    they're going to drink at the muddiest part of the pan
  • 1:27 - 1:31
    because the whole family's here and we can't drink at the best water
  • 1:31 - 1:34
    because that's reserved for the top-ranking family.
  • 1:34 - 1:36
    What's also very similar
  • 1:36 - 1:38
    is that you have elders in the group
  • 1:38 - 1:40
    that everyone reveres.
  • 1:40 - 1:41
    This is the matriarch,
  • 1:41 - 1:43
    and the other female is reaching over
  • 1:43 - 1:45
    and doing what's called a trunk to mouth
  • 1:45 - 1:47
    placing her trunk in the mouth,
  • 1:47 - 1:48
    and it's a sign of respect,
  • 1:48 - 1:51
    it's kind of like a handshake,
  • 1:51 - 1:53
    but it's also like a salute.
  • 1:53 - 1:56
    And this salute is learned at a very young age.
  • 1:56 - 1:59
    Now, ritual and bonding within the family
  • 1:59 - 2:02
    also facilitates coordinated activities.
  • 2:02 - 2:06
    So, here's a young female whose calf has fallen into the trough
  • 2:06 - 2:08
    and she doesn't know what to do and she panics.
  • 2:08 - 2:10
    Well, the older female, that's the matriarch,
  • 2:10 - 2:14
    she says, "No problem here," she just scoops the baby out.
  • 2:14 - 2:17
    Now, that's not true for a lot of different families,
  • 2:17 - 2:18
    they can't coordinate very well,
  • 2:18 - 2:21
    the younger females don't really know what to do,
  • 2:21 - 2:23
    but the older ones will just get down,
  • 2:23 - 2:26
    kneel down together and pick the baby out.
  • 2:26 - 2:28
    Another thing that's very similar
  • 2:28 - 2:31
    is the coming of age of teenage boys.
  • 2:31 - 2:34
    Male elephants at the age of about 12 to 15.
  • 2:34 - 2:37
    The biggest elephant in this photograph here
  • 2:37 - 2:40
    is an elephant who's about the leave the family.
  • 2:40 - 2:42
    He gets too big, he gets a little fresh,
  • 2:42 - 2:44
    the adult females had enough of him,
  • 2:44 - 2:45
    but he also is independent,
  • 2:45 - 2:48
    he wants to go out and play with the guys.
  • 2:48 - 2:52
    So what happens then is that you have this all male society,
  • 2:52 - 2:54
    very ritual male society.
  • 2:54 - 2:56
    Greg is our main dominant bull here,
  • 2:56 - 2:57
    you can see him in the middle.
  • 2:57 - 3:02
    He's got a huge posse, his following reveres him.
  • 3:02 - 3:04
    And it's very interesting how very good leaders,
  • 3:04 - 3:06
    very good dominant individuals
  • 3:06 - 3:09
    know how to titrate the carrot and the stick.
  • 3:09 - 3:11
    This guy's a master at it,
  • 3:11 - 3:13
    and there's other bullies out there
  • 3:13 - 3:15
    that want to kind of want to create their own little following,
  • 3:15 - 3:17
    but they can't do it because they're too agressive.
  • 3:17 - 3:19
    And so when he's not around
  • 3:19 - 3:23
    they try and sweet talk the underlings to come into their fold,
  • 3:23 - 3:25
    and they actually become less agressive.
  • 3:25 - 3:29
    So it's very interesting to see how politics play out
  • 3:29 - 3:33
    in these male and female societies.
  • 3:33 - 3:35
    Now back to the ladies here.
  • 3:35 - 3:38
    In a core family group you'll have a mother,
  • 3:38 - 3:39
    maybe even a grandmother,
  • 3:39 - 3:41
    her daughters and all of their offspring,
  • 3:41 - 3:43
    the male and female calves.
  • 3:43 - 3:45
    And what's very interesting here
  • 3:45 - 3:47
    is that how character makes a difference.
  • 3:47 - 3:50
    So each matriarch has a very different character.
  • 3:50 - 3:53
    These two characters are kind of curious,
  • 3:53 - 3:54
    they're uncertain,
  • 3:54 - 3:58
    whereas these other two characters are really agressive.
  • 3:58 - 4:01
    "We're going to charge first, ask questions later."
  • 4:01 - 4:04
    But then there are also matriarchs that say,
  • 4:04 - 4:06
    "Forget it! I'm going to run first
  • 4:06 - 4:07
    and then figure it out when we're in the bush
  • 4:07 - 4:09
    and it's safe."
  • 4:09 - 4:10
    But the wisest matriarch,
  • 4:10 - 4:12
    the matriarchs that succeed best
  • 4:12 - 4:15
    in all of the studies that have been done,
  • 4:15 - 4:17
    is the one that assesses the danger
  • 4:17 - 4:20
    and decides is this worth running away from
  • 4:20 - 4:22
    or is this not a big deal at all.
  • 4:22 - 4:26
    Now being social is super important for elephants
  • 4:26 - 4:28
    and of course right at the beginning,
  • 4:28 - 4:30
    just like early childhood development,
  • 4:30 - 4:32
    socialization is very important.
  • 4:32 - 4:35
    Bathing together, eating together, playing together,
  • 4:35 - 4:38
    rough housing, this is all very important
  • 4:38 - 4:39
    for social development.
  • 4:39 - 4:41
    And who hasn't tried to beat their sibling
  • 4:41 - 4:44
    to the head of the line coming into the water hole?
  • 4:44 - 4:48
    And these relationships from the beginning
  • 4:48 - 4:51
    is just like best friends forever for real.
  • 4:51 - 4:54
    These females are going to live together for life.
  • 4:54 - 4:57
    Now if it's a male, female they might know each other for life,
  • 4:57 - 5:00
    but it's really important to develop those bonds early on.
  • 5:00 - 5:04
    Those are the relationships that are going to save you later.
  • 5:04 - 5:07
    I'll show you a little schoolyard scenario here.
  • 5:07 - 5:10
    Where, I think if you just focus on what's happening here
  • 5:10 - 5:13
    you can see that we have the bully,
  • 5:13 - 5:16
    he's pulling on the trunk of this baby calf,
  • 5:16 - 5:18
    and then we have the diplomat
  • 5:18 - 5:19
    who's reaching over and saying,
  • 5:19 - 5:21
    "No, don't do that! Stop doing that!"
  • 5:21 - 5:24
    And then, of course, we have the bystander.
  • 5:24 - 5:26
    And how do you get these three different characters
  • 5:26 - 5:28
    within the family?
  • 5:28 - 5:31
    It's kind of fascinating to think that elephants
  • 5:31 - 5:32
    really are just like us.
  • 5:32 - 5:34
    And so I got curious about this
  • 5:34 - 5:38
    and I thought, "Well, what if you measure
  • 5:38 - 5:42
    the difference in character of a dominant female's calf
  • 5:42 - 5:44
    versus a lower-ranking female's calf,
  • 5:44 - 5:47
    and see what happens in their growing up."
  • 5:47 - 5:50
    And so we started doing this.
  • 5:50 - 5:51
    And you can see this little guy with his ears out,
  • 5:51 - 5:53
    really charging at you.
  • 5:53 - 5:55
    The difference between that character
  • 5:55 - 5:57
    and the character who holds back,
  • 5:57 - 5:59
    wants to touch mom,
  • 5:59 - 6:01
    isn't so certain about what's going on here.
  • 6:01 - 6:04
    But the other one's charging ahead all confident.
  • 6:04 - 6:07
    Well, we started measuring how far away
  • 6:07 - 6:09
    a calf will stray from mom,
  • 6:09 - 6:11
    how often do they touch others,
  • 6:11 - 6:13
    how often do they initiate play,
  • 6:13 - 6:17
    and then look at the dominance of the females, of their mothers.
  • 6:17 - 6:21
    And what we found is that socializing with the dominant calves
  • 6:21 - 6:25
    actually socialize more significantly more than the lower-ranking calves.
  • 6:25 - 6:27
    And what it looks like is
  • 6:27 - 6:30
    it's not that the lower-ranking calves don't want to play,
  • 6:30 - 6:32
    they're actually not allowed to interact
  • 6:32 - 6:33
    with the higher-ranking calves.
  • 6:33 - 6:36
    They get swatted away from the dominant females.
  • 6:36 - 6:38
    and so this is kind of the downside of,
  • 6:38 - 6:40
    okay we are very much like elephants,
  • 6:40 - 6:42
    elephants are as much like us,
  • 6:42 - 6:45
    but it's kind of for better or for worse
  • 6:45 - 6:47
    because I can also see this happening in humans
  • 6:47 - 6:50
    and maybe we should take a lesson from that.
  • 6:50 - 6:52
    One last thing that we found
  • 6:52 - 6:54
    is that the males will be the risk-takers,
  • 6:54 - 6:56
    they're more independent
  • 6:56 - 6:59
    and they're more likely to spend more time away from mom.
  • 6:59 - 7:01
    And that's very true in human societies
  • 7:01 - 7:03
    and with other social animals.
  • 7:03 - 7:05
    So I hope I've convinced you
  • 7:05 - 7:08
    that we have very similar lives to elephants
  • 7:08 - 7:12
    and that elephants have very individual, durable
  • 7:12 - 7:14
    characters that we've measured across years.
  • 7:14 - 7:16
    The bully always tends to be the bully
  • 7:16 - 7:18
    unless there's some kind of social upset,
  • 7:18 - 7:21
    and he decides he better be a softy
  • 7:21 - 7:24
    or else he's not going to gain favor at all.
  • 7:24 - 7:25
    And then you have the gentle giants
  • 7:25 - 7:27
    that are always going to be gentle.
  • 7:27 - 7:30
    The young males really need mentoring from the elders,
  • 7:30 - 7:33
    and those gentle giants are very good at doing that,
  • 7:33 - 7:35
    soliciting them.
  • 7:35 - 7:38
    Leaving family is a really hard things for the males,
  • 7:38 - 7:42
    but they survive and they figure out who to hang out with.
  • 7:42 - 7:45
    So, just to end here, I just wanted to say that
  • 7:45 - 7:47
    since they are so similar to us,
  • 7:47 - 7:49
    and have these characters,
  • 7:49 - 7:51
    I hope when you see them on TV
  • 7:51 - 7:53
    or you go out and you're lucky enough to see them in the wild,
  • 7:53 - 7:55
    that maybe you'll think of them
  • 7:55 - 7:58
    as individual characters deserving of our attention,
  • 7:58 - 8:01
    and also deserving of our protection. Thank you.

Description:

View full lesson: http://ed.ted.com/lessons/the-family-structure-of-elephants-caitlin-o-connell-rodwell

Biologist Caitlin O'Connell-Rodwell has come to one big conclusion from her last twenty years studying elephants -- they're just like us. In this TEDYouth Talk, O'Connell-Rodwell details her work observing these incredible, social animals, examining several individual (and very familiar) characters that play, bond and argue in tight-knit extended families eerily similar to our own.
