Are we sexual omnivores? | Christopher Ryan

August 7, 2019

I’m going to go off script and make Chris quite nervous here by making this audience participation. All right. Are you with me? Yeah. Yeah. All right. So what I’d like to do is have you raise your hand if you’ve ever heard a
heterosexual couple having sex. Could be the neighbors, hotel room, your parents. Sorry. Okay. Pretty much everybody. Now raise your hand if the man was making more noise than the woman. I see one guy there. It doesn’t count if it was you, sir. (Laughter) So his hand’s down. And one woman. Okay. Sitting next to a loud guy. Now what does this tell us? It tells us that human beings make noise when they have sex, and it’s generally the woman who makes more noise. This is known as female copulatory vocalization to the clipboard crowd. I wasn’t even going to mention this, but somebody told me that Meg Ryan might be here, and she is the world’s most famous female copulatory vocalizer. So I thought, got to talk about that. We’ll get back to that a little bit later. Let me start by saying human beings are not descended from apes, despite what you may have heard. We are apes. We are more closely related
to the chimp and the bonobo than the African elephant is to the Indian elephant, as Jared Diamond pointed
out in one of his early books. We’re more closely related to chimps and bonobos than chimps and bonobos are related to any other primate — gorillas, orangutans, what have you. So we’re extremely closely related to them, and as you’ll see in terms of our behavior, we’ve got some relationship as well. So what I’m asking today, the question I want to explore with you today is, what kind of ape are we in terms of our sexuality? Now, since Darwin’s day there’s been what Cacilda and I have called the standard narrative of human sexual evolution, and you’re all familiar with it, even if you haven’t read this stuff. The idea is that, as part of human nature, from the beginning of our species’ time, men have sort of leased
women’s reproductive potential by providing them with certain goods and services. Generally we’re talking about meat, shelter, status, protection, things like that. And in exchange, women have offered fidelity, or at least a promise of fidelity. Now this sets men and women up
in an oppositional relationship. The war between the sexes is built right into
our DNA, according to this vision. Right? What Cacilda and I have argued is that no, this economic relationship, this oppositional relationship, is actually an artifact of agriculture, which only arose about 10,000
years ago at the earliest. Anatomically modern human beings have been around for about 200,000 years, so we’re talking about five percent, at most, of our time as a modern, distinct species. So before agriculture, before the agricultural revolution, it’s important to understand that human beings lived in hunter-gatherer groups that are characterized wherever they’re found in the world by what anthropologists called fierce egalitarianism. They not only share things, they demand that things be shared: meat, shelter, protection, all these things that were supposedly being traded to women for their sexual fidelity, it turns out, are shared widely among these societies. Now I’m not saying that our ancestors were noble savages, and I’m not saying modern day hunter-gatherers
are noble savages either. What I’m saying is that this is simply the best way to mitigate risk in a foraging context. And there’s really no argument
about this among anthropologists. All Cacilda and I have done is extend
this sharing behavior to sexuality. So we’ve argued that human sexuality has essentially evolved, until agriculture, as a way of establishing and maintaining the complex, flexible social systems, networks, that our ancestors were very good at, and that’s why our species has survived so well. Now, this makes some people uncomfortable, and so I always need to take
a moment in these talks to say, listen, I’m saying our ancestors were promiscuous, but I’m not saying they were
having sex with strangers. There were no strangers. Right? In a hunter-gatherer band, there are no strangers. You’ve known these people your entire life. So I’m saying, yes, there were
overlapping sexual relationships, that our ancestors probably had
several different sexual relationships going on at any given moment in their adult lives. But I’m not saying they were
having sex with strangers. I’m not saying that they didn’t love the
people they were having sex with. And I’m not saying there was
no pair-bonding going on. I’m just saying it wasn’t sexually exclusive. And those of us who have
chosen to be monogamous — my parents, for example, have been married for 52 years monogamously, and if it wasn’t monogamously, Mom and Dad, I don’t want to hear about it— I’m not criticizing this and I’m not saying there’s anything wrong with this. What I’m saying is that to argue that our ancestors were sexual omnivores is no more a criticism of monogamy than to argue that our ancestors
were dietary omnivores is a criticism of vegetarianism. You can choose to be a vegetarian, but don’t think that just because
you’ve made that decision, bacon suddenly stops smelling good. Okay? So this is my point. (Laughter) That one took a minute to sink in, huh? Now, in addition to being a great genius, a wonderful man, a wonderful husband, a wonderful father, Charles Darwin was also a world-class Victorian prude. All right? He was perplexed by the sexual swellings of certain primates, including chimps and bonobos, because these sexual swellings tend to provoke many males to mate with the females. So he couldn’t understand why on Earth would
the female have developed this thing if all they were supposed to be doing
is forming their pair bond, right? Chimps and bonobos, Darwin didn’t really know this, but chimps and bonobos mate one to four times per hour with up to a dozen males per day when they have their sexual swellings. Interestingly, chimps have sexual swellings through 40 percent, roughly, of their menstrual cycle, bonobos 90 percent, and humans are among the
only species on the planet where the female is available for sex throughout the menstrual cycle, whether she’s menstruating,
whether she’s post-menopausal, whether she’s already pregnant. This is vanishingly rare among mammals. So it’s a very interesting aspect of human sexuality. Now, Darwin ignored the reflections of the sexual swelling in his own day, as scientists tend to do sometimes. So what we’re talking about is sperm competition. Now the average human ejaculate
has about 300 million sperm cells, so it’s already a competitive environment. The question is whether these sperm are
competing against other men’s sperm or just their own. There’s a lot to talk about in this chart. The one thing I’ll call your attention to right away is the little musical note above the
female chimp and bonobo and human. That indicates female copulatory vocalization. Just look at the numbers. The average human has sex about 1,000 times per birth. If that number seems high for some of you, I assure you it seems low for others in the room. We share that ratio with chimps and bonobos. We don’t share it with the other three apes, the gorilla, the orangutan and the gibbon, who are more typical of mammals, having sex only about a dozen times per birth. Humans and bonobos are the only
animals that have sex face-to-face when both of them are alive. (Laughter) And you’ll see that the human, chimp and bonobo all have external testicles, which in our book we equate to a special fridge you have in the garage just for beer. If you’re the kind of guy who has a beer fridge in the garage, you expect a party to happen at any moment, and you need to be ready. That’s what the external testicles are. They keep the sperm cells cool so you can have frequent ejaculations. I’m sorry. It’s true. The human, some of you will be happy to hear, has the largest, thickest penis of any primate. Now, this evidence goes way beyond anatomy. It goes into anthropology as well. Historical records are full of accounts of people around the world who have sexual practices that should be impossible given what we have assumed
about human sexual evolution. These women are the Mosuo
from southwestern China. In their society, everyone, men and women, are completely sexually autonomous. There’s no shame associated with sexual behavior. Women have hundreds of partners. It doesn’t matter. Nobody cares.
Nobody gossips. It’s not an issue. When the woman becomes pregnant, the child is cared for by her,
her sisters, and her brothers. The biological father is a nonissue. On the other side of the planet, in the Amazon, we’ve got many tribes which practice what anthropologists call partible paternity. These people actually believe — and they have no contact among them, no common language or anything, so it’s not an idea that spread, it’s an idea that’s arisen around the world — they believe that a fetus is literally made of accumulated semen. So a woman who wants to have a child who’s smart and funny and strong makes sure she has lots of sex with the smart guy, the funny guy and the strong guy, to get the essence of each of
these men into the baby, and then when the child is born, these different men will come forward and acknowledge their paternity of the child. So paternity is actually sort of a team endeavor in this society. So there are all sorts of examples like this that we go through in the book. Now, why does this matter? Edward Wilson says we need to understand that human sexuality is first a bonding device and only secondarily procreation. I think that’s true. This matters because our evolved sexuality is in direct conflict with many aspects of the modern world. The contradictions between what we’re told we should feel and what we actually do feel generates a huge amount of unnecessary suffering. My hope is that a more accurate, updated understanding of human sexuality will lead us to have greater tolerance for ourselves, for each other, greater respect for unconventional
relationship configurations like same-sex marriage or polyamorous unions, and that we’ll finally put to rest the idea that men have some innate, instinctive right to monitor and control women’s sexual behavior. (Applause) Thank you. And we’ll see that it’s not only gay people that have to come out of the closet. We all have closets we have to come out of. Right? And when we do come out of those closets, we’ll recognize that our fight is not with each other, our fight is with an outdated,
Victorian sense of human sexuality that conflates desire with property rights, generates shame and confusion in place of understanding and empathy. It’s time we moved beyond Mars and Venus, because the truth is that men are from Africa and women are from Africa. Thank you. (Applause) Chris Anderson: Thank you.
Christopher Ryan: Thank you. CA: So a question. It’s so perplexing, trying to use arguments about evolutionary history to turn that into what we ought to do today. Someone could give a talk and say, look at us, we’ve got these really sharp teeth and muscles and a brain that’s really good at throwing weapons, and if you look at lots of societies around the world, you’ll see very high rates of violence. Nonviolence is a choice like vegetarianism, but it’s not who you are. How is that different from the talk you gave? CR: Well first of all, the evidence for high levels of violence in prehistory is very debatable. But that’s just an example. Certainly, you know, lots of people say to me, just because we lived a certain way in the past doesn’t mean we should live that
way now, and I agree with that. Everyone has to respond to the modern world. But the body does have its inherent evolved trajectories. And so you could live on
McDonald’s and milkshakes, but your body will rebel against
that. We have appetites. I think it was Schopenhauer who said, a person can do what they want but not want what they want. And so what I’m arguing against is the shame that’s associated with desires. It’s the idea that if you love your husband or wife but you still are attracted to other people, there’s something wrong with you, there’s something wrong with your marriage, something wrong with your partner. I think a lot of families are fractured by unrealistic expectations that are based upon this false
vision of human sexuality. That’s what I’m trying to get at. CA: Thank you. Communicated
powerfully. Thanks a lot. CR: Thank you, Chris.

    5:38 as a vegetarian myself, bacon smells disgusting to me. i have to force myself and be tolerant(and i am) when someone eats meat with me at the table. it's unpleasant to me to even smell it while enjoying my own meal. my brain and my senses have changed from so many years not eating meat. i can't imagine going back even if i would want to, to put that disgusting dead animal flesh into my mouth, it just makes me cringe. maybe you like meat, but don't speak for everyone else. i'm also not speaking for 100% of vegetarians, but at least i can testify this is 100% true for me!

    Ryan implies that by poking a hole in one explanation of how human monogamy developed, he has completely invalidated the idea that human monogamy is instinctual. That strikes me as intellectually lazy, and not up to the modern standards of scientific rigor. I suspect that he arrived at the idea that we were promiscuous up until the development of agriculture more to support a preexisting worldview, than as an unbiased conclusion based upon the available evidence.

    There are numerous plausible causes for the development of human monogamy that do not depend upon social conditions that likely only became widespread after the development of agriculture. Desmond Morris, for example, suggests that it was simply selected for because those human groups that practiced it more had reduced levels of male competition within them, which allowed those groups to cooperate more effectively and out-compete those that practiced it less.

    I find it strange that Ryan seems to implicitly acknowledge (at 5:00) that we humans have some propensity to form sexual pairbonds, while asserting that we evolved in an environment of promiscuity. It seems far more difficult to me to describe how we would evolve that trait in an environment where sexual promiscuity is the dominant norm than one in which sexual monogamy is the dominant norm; and in this talk at least, Ryan makes no attempt to explain it at all.

    I'd say the big difference between say natural violence and natural attraction is that one can be handled in a positive way and the other is inherently negative. Violence burns the heart of the violent. All sexuality can be positive as long as it does not conflict with higher priorities and is not treated violently.

    The issue is some of us hold beliefs at a higher priority that condemn our sexualities to extreme measures, and I encourage everyone to negotiate with themselves and find an acceptable and positive lifestyle that includes healthy sexuality.

    This featured at the end of a piece about free will. The beginning of the quote is: “Everything is determined, the beginning as well as the end, by forces over which we have no control.  It is determined for insects as well as for the stars.  Human beings, vegetables or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.”

    When I read comments I always get utterly frustrated. There's this clear division between those that communicate thoughts formulated with the intention of incorporating their need for truth, by considering facts/theories, and those for whom emotion is the greatest determiner of their opinion's content.
    I read the latter's comments and I am always struck by the lack of substance, but, clearly, there's passion!
    Granted, beliefs are powerful, but on balance I'd like to see our specie rely a great deal less upon them; not every intellectual or emotional challenge, in life, is a "Nail."

    Thanks a lot Mr. Ryan for this talk. I have just been reading about that from the spanish author Casilda Rodrigañez Bustos in her books, which are unfortunately not yet translated into any other language, in which she doesn´t only talk about human sexuality but also about anthropology, social control, human bonding, orgasmic, sexual birth and extero-gestation. Fortunately more and more scientists and authors are going into this complex issue that will for sure have important consequences in the future lives of human beings. We are not necessarily what we were told we are, and many of us have always felt deep inside our gut that there was something wrong about the way we are living.

  • Reply Jonathan Weber October 18, 2014 at 12:45 am

    Let's put it this way; When creatures are monogamous, they pair bond for life. You know what this means? It is basically impossible for them to be attracted to anyone else once they have pair bonded.

    Think about it. Once you date someone, you can't even acknowledge other men/women as attractive. If you two break up, you wouln't be able to form another bond.

    Clearly that isn't how humans work. We choose to be sexually exclusive with one partner at a time, and perhaps that's for the best, but that doesn't mean we're naturally monogamous, it means we are polygamous and choosing serial monogamy (which, by the way, is technically a type of polygamy.)

  • Reply Melissa Samworth December 16, 2014 at 2:56 am

    But we're not hunter gatherers anymore. Perhaps in such a situation acting this way makes sense. It doesn't equate to promiscuity in today's society, which is different that the hunter-gatherer clan setup in more than a few ways.

  • Reply KennywalkerTV January 4, 2015 at 3:39 am

    Listen, the reason loves means anything is because we have all of the desires you speak of and CHOOSE to stay loyal. It wouldn't mean anything if our attraction to everyone else just faded. One day I'm gonna be with a woman and I will know in my heart how she could have done waaaayy better then me and that humility gained from the fact that she said yes to me when she really didn't have to is what will make our relationship strong. Hopefully she will feel the same way about me.

    If you want your relationships to mean anything to anyone YOU WILL SUFFER. You always sacrifice for anything you claim to love; that's the proof it actually exists.

    I'm surprised Chris depicts the current sexual dynamic that needs fixing as being men's assumed innate right to monitor and control women's sexual behaviour (which gets a very feminine sounding round of applause) when it seems to me that it is women who insist more on monogamy and call promiscuity "cheating" because that suits their situation more than it does the man. In my experience women seek to control men's sexual behaviour far more vehemently than vice versa.

    Also, don't feel like you're a perv just because you're compelled to stare at a high school girl, or any girl who's gone through puberty, even though acting on it carries legal consequences these days.

    You know, you’re really growing on me , pardon the PUN I find your talks very entertaining.

    And I have a close relative that became intrigued with your online discussions .

    I studied psych but I like to tell people I got my BA so long ago , I think it’s expired!

    That said, I have a recollection of studying “ the psychology of emotions “ from a historical perspective and practical.
    fabulous professor dr Joyce Hoffman – anyway ,
    I’d like to ask what you feel Aristotle contributed to the basic understanding of human emotions and what gives rise to them. ?

    I may recall incorrectly, but I seem to remember he wrote about universal human emotion , and included as one of those emotions was envy and jealousy. ( of ones mate )
    Though you may be a strict behaviorist and from that point of view , as I learned from a great professor and long-time friend, the late Dr john Budz, gave a similar lecture – a magnificent performance really , when he taught courses in behavioral psychology regarding learned behavior, biofeedback and its success as an effective treatment to if you will “unlearn” behavior . And you might espouse as he did the work of BF Skinner and operant conditioning.

    I’m interested to know your thoughts . ( people reading – these unfamiliar possibly words become 2nd nature , when you hear them a million times) But I guess I’ve had these questions for a while .
    Nature or nurture ? Genetics or learned psychological traits.
    Correct me if I’m wrong , but I hear yours as an optimistic message that we as human beings may have far more control over our so called innate emotions and the ability to “change “them ?
    Thanks for your attention / indulging me

    I wanted to see where he was going with vocalization. I would assume that it is to draw attention for other men.

    I am proposing that the Electronegativity (Periodic) Table is actually an indication of matter's innate consciousness. The inherent give/take we see in the formation of molecules is actually their consciousness manifesting.

    Talks about his monogamous parents that made him into the "dr" he is today. Then said that humans are meant to have many sexual partners? I'm sure all the adults that had slutty mothers and fathers growing up loved it. Just think Eminems mom in 8 mile!

    He also said that if his parents weren't monogamous he didn't want to hear about it! Almost as If he would have been physiologically and emotionally disturbed by that information. Suggesting that even the bonded Pairs offspring has a desire for the family unit to stay together.

    Less funky, fashionable or palatable truth could be that women wanted the husband & wife set up to have security against other dominant females, because to 'be owned' proffers rights of protection. Also seems that the Hegemony of marriage is a security women desire more than men. Chris is saying the opposite.

    Total B.S. Just trying to justify hypersexuality. How about AIDS and other STDs? How about rape? Pedophilia? How about all the damage caused by infidelity? This is a really narrow minded argument.
