Homosexuality: it's about survival, not sex | James O'Keefe | TEDxTallaght
-
0:13 - 0:15One summer evening,
-
0:15 - 0:20my eighteen-year-old son Jimmy
said he wanted to talk. -
0:20 - 0:26So, after my wife Joan and I got his three
much younger siblings tucked in -
0:26 - 0:28and read their bedtime stories,
-
0:29 - 0:32Joan and I sat down in our bedroom.
-
0:32 - 0:37Jimmy came in and closed
the door behind him. -
0:38 - 0:42And he sat down on a chair across
from the bed where we were sitting, -
0:42 - 0:45and says, "Mom and Dad,
I have something important to tell you, -
0:45 - 0:50and it's not a problem, it's not
a bad thing, it's just different." -
0:50 - 0:52We said, "Okay."
-
0:53 - 0:59And he looked at us in earnest,
and he said, "I'm gay." -
1:01 - 1:05So, after a few seconds
of deafening silence, -
1:05 - 1:11Joan takes a deep breath and says,
"Jimmy, we will love whoever you love." -
1:13 - 1:16That was about 12 years ago
when he came out to us, -
1:16 - 1:18and I'll have to admit that, at the time,
-
1:18 - 1:21Joan and I did think
this could be a problem, -
1:21 - 1:24for his safety, even.
-
1:24 - 1:28And as his father, I had this feeling
that, somehow, I had failed him, -
1:28 - 1:34and maybe, because of that, he wouldn't
have a chance to have kids of his own. -
1:34 - 1:36So, I'm a cardiologist,
-
1:36 - 1:42and I like to imagine the world through
the eyes of a hunter-gatherer ancestor -
1:42 - 1:45for clues about how to thrive
in the modern world, -
1:45 - 1:48but, viewed in the light of evolution,
-
1:48 - 1:52homosexuality seems to be a real
self-defeating non-productive strategy. -
1:52 - 1:56I mean, gays have 80% fewer kids
than heterosexuals. -
1:56 - 1:59This is a trait that ought to go extinct
in a few generations, -
1:59 - 2:01but down through recorded history,
-
2:01 - 2:04in every culture,
and many animal species as well, -
2:04 - 2:08homosexuality's been a small,
but distinct subgroup. -
2:09 - 2:11If this were a genetic error,
-
2:11 - 2:15natural selection should have long ago
called this from the gene pool. -
2:15 - 2:18So, while I was pondering this,
-
2:18 - 2:23this paradox about the natural
origins of homosexuality, -
2:24 - 2:26our babies grew up.
-
2:27 - 2:31Jimmy has three younger
siblings who adore him. -
2:31 - 2:34He has this magnetism
and this charming wit -
2:34 - 2:37that helps them feel happy and relaxed.
-
2:37 - 2:40And one day, while contemplating
this "Jimmy effect," -
2:40 - 2:44it suddenly dawned on me:
homosexuality is not so much about sex; -
2:44 - 2:48it's really more about survival,
the family's survival. -
2:49 - 2:53So us, Homo sapiens, we are among
the most social species on Earth. -
2:53 - 2:58For us, it's not just a kill-or-be-killed
struggle for existence. -
2:58 - 3:02It's a snuggle for existence, you know.
-
3:02 - 3:04An ability to love our family
and bond with our group -
3:04 - 3:08determines, in many cases,
whether we survive or perish. -
3:08 - 3:10So it's the survival
of the fittest family, -
3:10 - 3:12not the fittest individual.
-
3:13 - 3:18So, you share 50% of your DNA
with your siblings. -
3:18 - 3:21Your nieces and nephews
share 25% of your DNA. -
3:21 - 3:23Frоm evolution's perspective,
-
3:23 - 3:26you have the same genetic success
if you raise one child on your own -
3:26 - 3:29or you enable a sibling
to raise two children. -
3:29 - 3:31Frоm evolution's perspective,
-
3:32 - 3:35this is all about
cooperation and altruism. -
3:35 - 3:38Homosexuality is
genetically-programmed altruism. -
3:38 - 3:42Gays are designed by nature
to help us be kind to one another, -
3:42 - 3:44like Ellen DeGeneres says.
-
3:44 - 3:46(Laughter)
-
3:46 - 3:48So, E. O. Wilson,
-
3:49 - 3:53probably the greatest evolutionary
biologist since Darwin himself, -
3:53 - 3:58says homosexuality gives advantages
to the group by specialized talents -
3:58 - 4:01and unusual qualities of personality.
-
4:02 - 4:06So, a society that condemns
homosexuality harms itself. -
4:07 - 4:11So, what does professor Wilson mean
by "unusual qualities of personality"? -
4:11 - 4:15Well, let me tell you
about our dear family friend Jenny. -
4:15 - 4:19She is 35, single, straight.
-
4:19 - 4:24She was telling us she is looking
for a man who's smart and funny, -
4:24 - 4:27who's sensitive, who's a good listener.
-
4:27 - 4:30And she says she occasionally
meets a guy like that, -
4:30 - 4:34but she complains, "You know,
he usually has a boyfriend already!" -
4:34 - 4:35(Laughter)
-
4:35 - 4:39So, although people tend to obsess over
what gays do or don't do in a bedroom, -
4:39 - 4:44it's really this distinctive personality
and a strong intellect -
4:44 - 4:48that are more critical,
from evolution's perspective. -
4:49 - 4:51So, scientific studies do indeed show
-
4:51 - 4:54that people in the sexual minority
tend to be intelligent, -
4:54 - 4:58particularly when it comes
to emotional intelligence. -
4:59 - 5:02So, this study showed
-
5:03 - 5:06that boys and girls who scored
in a very bright IQ range -
5:06 - 5:08were twice as likely
to be homosexual as adults -
5:08 - 5:12as those children who scored
in the low to average range. -
5:12 - 5:16And, among gay males,
on psychological testing, -
5:17 - 5:23gay males tend to score higher
in metrics of compassion and cooperation, -
5:23 - 5:26and lower in metrics of hostility.
-
5:27 - 5:32So, if Michelangelo had been straight,
-
5:32 - 5:35he might have just wallpapered
the Sistine Chapel. -
5:35 - 5:37(Laughter)
-
5:38 - 5:41Songwriter Sam Austin says,
-
5:41 - 5:43"Homosexuality is God's way of ensuring
-
5:43 - 5:45the truly gifted aren't
burdened with children." -
5:45 - 5:47(Laughter)
-
5:51 - 5:55But today, in the US, about 2 out of every
25 people are in the sexual minority. -
5:56 - 5:59Diversity is nature's secret weapon.
-
5:59 - 6:03If all males were gay,
that would be a problem, -
6:03 - 6:07but if all males were warriors,
we'd always be at war. -
6:08 - 6:11The recipe for a successful human culture
-
6:11 - 6:15is a synergy of many
different ingredients. -
6:15 - 6:17Homosexuality is like a catalyst
-
6:17 - 6:20to help emotionally connect
groups of people together. -
6:21 - 6:23For heterosexuals, to disapprove of gays
-
6:23 - 6:29is kind of like the white flour
in bread disapproving of the yeast. -
6:32 - 6:36So, if your genome is your hardware,
epigenetics is your software. -
6:36 - 6:41You have many different DNA programs
downloaded on your DNA, -
6:41 - 6:44and epigenetics chooses
from among these to determine -
6:44 - 6:48which version of you actually is
the best fit for the environment. -
6:49 - 6:52So, ants, you probably didn't know it,
but are another highly social species -
6:52 - 6:56that have epigenetic mechanisms
very similar to humans. -
6:56 - 7:00These two are identical twin sisters, huh?
-
7:01 - 7:05Even though their DNA sequences
are exactly the same, -
7:05 - 7:08this one, the worker,
-
7:08 - 7:11is a brainy little scurrier
who goes out looking for food, -
7:11 - 7:14whereas the one on the right, the soldier,
-
7:14 - 7:17is obviously a brawny one
to fight off enemies. -
7:18 - 7:23So, the queen ant
epigenetically orchestrates this -
7:23 - 7:27by placing different epigenetic tags
on the developing ants. -
7:27 - 7:29So -
-
7:31 - 7:34she places tags
when the colony is under attack -
7:34 - 7:39to uncoil the DNA and light up
the genes to make the soldier, -
7:39 - 7:46but when the colony is hungry,
she puts different tags to uncoil the DNA -
7:46 - 7:51and epigenetically create
the conditions for the worker. -
7:51 - 7:56So, in this way, the epigenetics -
-
7:56 - 8:01the dynamic power of epigenetics
changes our genetic expression, -
8:01 - 8:05so that we're born with traits
that allow us and our families -
8:05 - 8:08the best chance to succeed
in the current conditions. -
8:09 - 8:14So, you probably have
gay genes in your DNA, -
8:14 - 8:19but, unless they were turned on
in your mother's womb, -
8:19 - 8:21they remain coiled up and silent.
-
8:22 - 8:25A recent groundbreaking
study from UCLA found -
8:25 - 8:29that, by looking at a group of men,
some gay, some straight, -
8:29 - 8:32and looking at epigenetic tags
in nine different sites, -
8:32 - 8:37they could predict with 70% accuracy
their sexual orientation. -
8:38 - 8:43So, what conditions in the uterus
turn on those gay genes? -
8:44 - 8:46So, for a male,
-
8:47 - 8:49your chances of homosexuality
increase in proportion -
8:49 - 8:54to the number of previous baby boys
who inhabited your mother's uterus. -
8:54 - 8:57So, for every older
biological brother you have, -
8:57 - 9:01your chances of being born gay go up 33%.
-
9:01 - 9:05Long before we invented the pill,
-
9:05 - 9:09nature devised homosexuality
as a prescription for birth control. -
9:10 - 9:16After four straight, heterosexual males,
nature says, "Enough already!," -
9:18 - 9:22and the mom's immune system
switches on the epigenetic switch -
9:22 - 9:26so a gay male is born into the family.
-
9:26 - 9:29This one will not be overburdening
the clan with yet more mouths to feed -
9:29 - 9:33in the next generation
- sometimes more isn't better - -
9:33 - 9:35and he's not going to be
killing his brother -
9:35 - 9:37in a fight over who gets the girl.
-
9:38 - 9:42Thankfully, the sexual minority
these days have many options -
9:42 - 9:44for having kids of their own,
-
9:44 - 9:47and I have a hunch my gay son
may bless us with grandchildren -
9:47 - 9:51before our three straight children do.
-
9:52 - 9:56So, another gene,
this one on the X chromosome, -
9:56 - 9:58is called a "male-loving gene,"
-
9:58 - 10:01because, when it shows up in a female,
-
10:01 - 10:04she tends to mate early
and have a lot of kids, -
10:04 - 10:07but, when the male-loving gene
shows up in a male, -
10:07 - 10:09it predisposes to homosexuality.
-
10:09 - 10:12So, this is another gene
that balances a family -
10:12 - 10:14destined to have a large brood
of kids and grandkids -
10:14 - 10:19with an occasional gay son whose natural
tendency to promote togetherness -
10:19 - 10:23could improve the chances of survival
for the whole family. -
10:24 - 10:26Now, I apologize.
-
10:26 - 10:31We have a lot more science about
sexual orientation in men than in women, -
10:31 - 10:33so this talk is mostly about gay males.
-
10:33 - 10:35Though, I have no doubt
-
10:35 - 10:38that female homosexuality
is also a natural variation -
10:38 - 10:41that is advantageous
for the family and the community. -
10:42 - 10:45But Jimmy has no older brothers.
-
10:45 - 10:47Why is he gay?
-
10:48 - 10:52So, when Joan was pregnant with him,
-
10:52 - 10:56we discovered a large cancer
growing in her chest. -
10:57 - 10:59Metastasis in the neck.
-
10:59 - 11:01It was a scary time.
-
11:02 - 11:05She had radiation therapy to her chest
-
11:05 - 11:08while Jimmy was still
in the third trimester. -
11:09 - 11:12It was a rocky start for little Jimmy.
-
11:14 - 11:20Miraculously, they both survived
and are in great health today. -
11:20 - 11:23But, in fact,
-
11:24 - 11:29severe prenatal stress
does predispose to homosexuality. -
11:29 - 11:32In this study, 37% of gay males
-
11:32 - 11:35reported their mothers
suffered severe prenatal stress -
11:36 - 11:41compared to only 3%
of heterosexual males' moms. -
11:44 - 11:50This is kind of like the queen ant,
-
11:50 - 11:54where the mom is placing
epigenetic markers on the baby -
11:54 - 12:01to change his identity to help
the future welfare of the family. -
12:02 - 12:05It's as if the mom was saying,
"I'm in trouble here. -
12:05 - 12:11I need a kind and clever ally
to help me hold this family together." -
12:13 - 12:14So, to summarize,
-
12:16 - 12:18if the family is flushed
with plenty of kids -
12:18 - 12:20and/or it's a stressful place and time,
-
12:20 - 12:23nature occasionally flips
these epigenetics switches -
12:23 - 12:24to turn on the gay genes.
-
12:24 - 12:26This alters brain development,
-
12:26 - 12:32that changes sexual orientation
and also improves emotional intelligence. -
12:34 - 12:37I have no doubt that Jimmy was born gay.
-
12:37 - 12:39Here's his first birthday party.
-
12:39 - 12:41(Laughter)
-
12:41 - 12:45When he was three, he said, "Mommy,
when I grow up, I want to marry Daddy." -
12:45 - 12:47(Laughter)
-
12:47 - 12:50Now, some parents send their kid away,
you know, well-meaning parents, -
12:50 - 12:54to a conversion camp
to pray away the gay. -
12:54 - 12:56You might as well send the kid to a camp
-
12:56 - 12:58to convert his eye color
from brown to blue. -
12:58 - 13:00Not happening!
-
13:01 - 13:04But Jimmy is like social glue
holding our family together. -
13:04 - 13:08You know, whether his brother Evan
gets beat up in a bar fight, -
13:08 - 13:12or his sister Caroline
gets dumped by a boyfriend, -
13:12 - 13:16or his sister Kathleen gets busted
for plagiarizing Wikipedia - -
13:16 - 13:18(Laughter)
-
13:19 - 13:22they know Jimmy's made them feel
-
13:22 - 13:26like they belong to something
bigger than their problems. -
13:28 - 13:31So, storytelling is the great
survival skill of the Irish, -
13:31 - 13:34and, right here in Dublin, 162 years ago,
-
13:34 - 13:38one of your finest storytellers was born:
-
13:38 - 13:40Oscar Wilde.
-
13:40 - 13:43Oscar ran away to the University of Oxford
-
13:43 - 13:46where he met a young poet
named Bosie Douglas. -
13:46 - 13:48Their long-standing
openly gay relationship -
13:48 - 13:53infuriated and humiliated
Bosie's father, Lord Queensburry - -
13:53 - 13:54I'm not making this up -
-
13:54 - 13:56(Laughter)
-
13:57 - 14:02who was so mad that he eventually
had Oscar arrested for gross indecency, -
14:02 - 14:05thrown into a dungeon
for two years of hard labor. -
14:06 - 14:10Oscar died three years later, a young man.
-
14:11 - 14:16Oscar wrote, "Always forgive your enemies.
Nothing annoys them so much." -
14:16 - 14:17(Laughter)
-
14:17 - 14:22But these days, open homophobia is being
replaced by more of a subtle heterosexism -
14:22 - 14:25where people in the sexual minority
-
14:25 - 14:27are often considered
second-class citizens. -
14:28 - 14:30Boy George says, "There's this illusion
-
14:30 - 14:33that homosexuals have sex
and heterosexuals fall in love. -
14:33 - 14:36That's completely untrue.
We all want to be loved." -
14:36 - 14:40I agree: among all the things in life
it'd be hardest to live without, -
14:41 - 14:43love would come first.
-
14:43 - 14:47But indoor plumbing and toilet paper
would be pretty high up there too, right? -
14:47 - 14:49(Laughter)
-
14:49 - 14:51I want to tell you about one more study,
-
14:51 - 14:55this one a heartbreaking,
nationwide study, from the US, -
14:55 - 15:00that looked at US teens, and they found
that those in the sexual minority -
15:00 - 15:02were twice as likely to be bullied,
-
15:02 - 15:05five times more likely
to have attempted suicide. -
15:05 - 15:09Twenty-nine percent of gay teens
had tried to kill themselves. -
15:09 - 15:12These days, around the world,
in many countries, -
15:12 - 15:16it's illegal to have same-sex
physical intimacy. -
15:16 - 15:20In many countries,
it's punishable by death. -
15:20 - 15:22In the red countries,
it's punishable by imprisonment. -
15:22 - 15:26In India, the law states
14 years to life, -
15:26 - 15:30because "homosexuality
is against the order of nature." -
15:33 - 15:35Except that it's not!
-
15:35 - 15:40Nature prescribes homosexuality
at specific times and places, -
15:40 - 15:43and endows these people
with special traits -
15:43 - 15:46that help the people around them flourish.
-
15:46 - 15:48What is against the order of nature
-
15:48 - 15:51is the ongoing persecution
of the sexual minority. -
15:51 - 15:54These are not confused or defective people
-
15:54 - 15:57that need to be cured,
or punished, or ostracized. -
15:58 - 16:03They need to be accepted,
-
16:04 - 16:06for who they are, and embraced.
-
16:07 - 16:09They make us better.
-
16:10 - 16:15If you had told me 30 years ago,
as I held my baby boy, -
16:15 - 16:17that he would grow up to be gay,
-
16:17 - 16:19I would have been devastated,
-
16:20 - 16:24but looking back, I see Mother Nature
knew what she was doing! -
16:25 - 16:30Her clairvoyant intelligence,
forged during eons of evolution, -
16:30 - 16:35instinctively knew my family would need
the advantages of a gay son. -
16:36 - 16:37Now, admittedly,
-
16:37 - 16:41the science of homosexuality
is still in it's infancy, -
16:41 - 16:44but as his father,
what I can tell you for sure -
16:44 - 16:47is that Jimmy is exactly
who he was meant to be, -
16:48 - 16:52and my family is stronger and happier
because he's in our clan. -
16:54 - 16:55How about you?
-
16:56 - 16:58Can you set sex aside?
-
16:59 - 17:05Realize gay men and gay women
are essential to humanity? -
17:07 - 17:09We're like the ants.
-
17:09 - 17:14It's in our diversity where we find
our collective strength. -
17:14 - 17:16Thank you.
-
17:16 - 17:19(Applause) (Cheers)
