And most people live in a culture 62 00:03:03,809 --> 00:03:05,978 where they're expected at some point 63 00:03:06,062 --> 00:03:09,232 to make that rule a legal contract, called marriage. 64 00:03:09,732 --> 00:03:12,360 In many countries, breaking that rule is a crime. 65 00:03:12,944 --> 00:03:16,948 In the U.S., adultery is illegal in at least 20 states, 66 00:03:17,031 --> 00:03:18,950 and although they're rarely enforced, 67 00:03:19,242 --> 00:03:23,663 punishments can range from a $10 fine to three years in prison. 68 00:03:23,746 --> 00:03:26,958 If you are in a monogamous relationship for 50 years 69 00:03:27,041 --> 00:03:28,960 and you fell down once, you cheated once, 70 00:03:29,043 --> 00:03:31,212 the whole relationship was a lie and a failure. 71 00:03:31,295 --> 00:03:35,132 Most human beings have ambivalent impulses 72 00:03:35,216 --> 00:03:37,677 that it's nice to have someone you can rely on 73 00:03:37,760 --> 00:03:40,096 but there's also the temptation of novelty. 74 00:03:40,888 --> 00:03:43,516 Why would humans all around the world invent a rule 75 00:03:43,599 --> 00:03:45,142 that's so difficult to follow 76 00:03:45,226 --> 00:03:48,729 and treat breaking it as such an enormous betrayal? 77 00:03:48,813 --> 00:03:52,525 [narrator] Should a male have on his clothing so much as a strand of hair 78 00:03:52,608 --> 00:03:56,612 from a female not his wife, a serious crisis may result. 79 00:03:57,530 --> 00:04:01,367 For more than a century, there's been a culturally accepted explanation. 80 00:04:02,201 --> 00:04:03,244 Sound check. 81 00:04:03,953 --> 00:04:05,913 One. One. One. One. One. One. One. 82 00:04:05,997 --> 00:04:10,293 The standard narrative is the story that everybody knows. That men want to be free sexually and spread their seed around the world 83 00:04:14,755 --> 00:04:20,303 and women want to be very exclusive and particular and choose a provider, 84 00:04:20,386 --> 00:04:24,432 because they're vulnerable and the children need to be taken care of. 85 00:04:24,515 --> 00:04:27,101 Women trade sexual fidelity to men 86 00:04:27,184 --> 00:04:30,229 in exchange for goods and services, essentially. 87 00:04:31,647 --> 00:04:32,815 In this narrative, 88 00:04:32,898 --> 00:04:36,485 there's another reason why men wouldn't want women to sleep around. 89 00:04:36,569 --> 00:04:39,363 If a baby comes out of a woman's body, 90 00:04:39,447 --> 00:04:43,326 there's no question but that she is genetically related to that baby. 91 00:04:43,409 --> 00:04:47,246 The male has to take the woman's word for it. 92 00:04:47,330 --> 00:04:50,624 Biologists have known for a very long time that... 93 00:04:50,708 --> 00:04:56,213 men are far more inclined to seek multiple sexual partners. 94 00:04:56,297 --> 00:04:58,966 And the reason for that is really quite clear. 95 00:04:59,050 --> 00:05:02,678 [educator] Now in the first place, remember that the male sperm cells 96 00:05:02,762 --> 00:05:04,472 are being produced all the time, 97 00:05:04,555 --> 00:05:07,391 while only one egg cell is produced each month. 98 00:05:07,850 --> 00:05:11,771 There's very good, and I don't mean ethically good, but very understandable 99 00:05:11,854 --> 00:05:16,484 evolutionary payoff for males as being randy bastards. 100 00:05:16,567 --> 00:05:17,401 [inaudible] 101 00:05:17,485 --> 00:05:20,363 But there's one big issue with that explanation 102 00:05:20,446 --> 00:05:23,407 of promiscuous, possessive men and demure women. 103 00:05:24,075 --> 00:05:28,162 At lots of points in time, in places in the world, people didn't follow it. 104 00:05:28,245 --> 00:05:30,748 Anatomically modern human beings 105 00:05:30,873 --> 00:05:33,292 have existed for at least 300,000 years. 106 00:05:33,793 --> 00:05:37,630 And for more than 90 percent of that time, we lived as hunter-gatherers. 107 00:05:40,383 --> 00:05:43,928 Anthropologists refer to them as fiercely egalitarian. 108 00:05:44,011 --> 00:05:47,681 There's no reason to think that our ancestors shared everything 109 00:05:47,765 --> 00:05:50,017 except sexual partners. 110 00:05:50,101 --> 00:05:54,063 Of course, we can't go back and interview our foraging ancestors, 111 00:05:54,146 --> 00:05:59,193 but we have the accounts of explorers and Europeans 112 00:05:59,276 --> 00:06:02,405 who first developed and saw these societies 113 00:06:02,488 --> 00:06:05,032 before they'd been much touched by outsiders. 114 00:06:05,116 --> 00:06:09,120 And they are surprised and shocked at the difference in sexual mores. 115 00:06:09,203 --> 00:06:11,372 There's a wonderful story that a Jesuit 116 00:06:11,455 --> 00:06:14,750 who lived with the Naskapi Indians for some time, and he would ask, 117 00:06:14,834 --> 00:06:17,670 "If you let your wives have this much freedom, 118 00:06:17,753 --> 00:06:21,173 how do you know that the child she bears will belong to you?" 119 00:06:21,257 --> 00:06:24,051 And he recorded the answer of the Indian: 120 00:06:31,851 --> 00:06:36,063 If a child is crying and the adult nearest to that child picks it up, 121 00:06:36,147 --> 00:06:38,732 nobody says, "Hey, hey. Your kid's crying." 122 00:06:38,816 --> 00:06:39,942 No, it's... 123 00:06:40,025 --> 00:06:44,363 there's a commonality to parenthood among hunter-gatherers. 124 00:06:44,447 --> 00:06:47,575 One of those groups are the Bari of Venezuela, 125 00:06:47,658 --> 00:06:50,327 where every man who sleeps with a woman while she's pregnant 126 00:06:50,411 --> 00:06:53,873 is considered a father of the child and helps provide for it. 127 00:06:53,956 --> 00:06:57,251 Now in our society, that would probably not work very well. 128 00:06:57,334 --> 00:06:58,752 I'm not recommending it. 129 00:06:59,295 --> 00:07:00,796 But in that society, 130 00:07:00,880 --> 00:07:06,552 the child who had several fathers named because she'd slept with several fathers 131 00:07:06,635 --> 00:07:09,805 actually had a much better chance of surviving to adulthood 132 00:07:09,889 --> 00:07:12,558 because those men contributed. 133 00:07:12,641 --> 00:07:16,061 Did you ever think of going with somebody else after you married me? 134 00:07:16,145 --> 00:07:17,354 What, are you crazy? 135 00:07:17,438 --> 00:07:20,691 We don't like to say we're open. We like to say we're slightly ajar. 136 00:07:20,774 --> 00:07:21,859 Exactly. 137 00:07:21,942 --> 00:07:23,903 That's not good in my way. 138 00:07:23,986 --> 00:07:27,573 In our language, also, they say, "Pati parmeshwar." 139 00:07:27,656 --> 00:07:29,617 That means "Husband is like God". 140 00:07:29,700 --> 00:07:32,495 -This is our culture. -Our culture. 141 00:07:32,578 --> 00:07:36,707 We actually kind of met through the non-monogamy "community". 142 00:07:36,790 --> 00:07:41,295 I define this relationship as this is my cohabitating partner 143 00:07:41,378 --> 00:07:43,380 -and we call each other otters. -Yeah. 144 00:07:43,464 --> 00:07:48,385 We are primary partners and our other partners are secondary partners. 145 00:07:48,469 --> 00:07:49,678 I find it really fascinating. 146 00:07:49,762 --> 00:07:54,642 I think about it a lot, like if I could ever do that, but I don't know if I could. 147 00:07:54,725 --> 00:07:58,229 I had a threesome with, like, two friends of mine that I initiated. 148 00:07:58,312 --> 00:08:01,357 I decided that it would be cool to experiment with multiple people 149 00:08:01,440 --> 00:08:03,567 with somebody I really loved and cared about. 150 00:08:03,651 --> 00:08:07,696 The queer community is berated with the idea that our relationships are lesser 151 00:08:07,780 --> 00:08:11,909 and that they're actually not up to par in the hetero-normative standard. 152 00:08:11,992 --> 00:08:13,160 And all of that is bull. 153 00:08:13,244 --> 00:08:17,081 We shouldn't be surprised that some cultures practice non-monogamy. 154 00:08:17,790 --> 00:08:22,378 Because in the animal world, true sexual monogamy is virtually unheard of. 155 00:08:24,672 --> 00:08:28,175 The most romantic creature might be the Diplozoon paradoxum, 156 00:08:28,300 --> 00:08:33,722 a parasitic tapeworm that literally fuses together with its partner for life. 157 00:08:34,139 --> 00:08:37,393 But humans aren't tapeworms or apes, 158 00:08:37,476 --> 00:08:41,522 and our closest relatives in the animal world are chimps and bonobos. 159 00:08:41,605 --> 00:08:44,191 [Christopher Ryan] We're closer related to chimps and bonobos 160 00:08:44,275 --> 00:08:47,111 than the Indian elephant is to the African elephant. 161 00:08:47,194 --> 00:08:50,614 [narrator] The close comparison exists in bone and muscle structure, 162 00:08:50,698 --> 00:08:55,369 and in the capability of responding to stimuli and solving problems. 163 00:08:55,452 --> 00:08:59,290 Clearly, chimps and bonobos are anything but monogamous. 164 00:08:59,373 --> 00:09:02,418 Bonobos have sex at the drop of a hat. 165 00:09:02,501 --> 00:09:07,089 [song] I know... that I just met you... 166 00:09:07,172 --> 00:09:10,050 They have sex to say hello, they have sex to say goodbye. 167 00:09:10,134 --> 00:09:11,844 They have sex when they're stressed out. 168 00:09:11,927 --> 00:09:14,430 For both male and female bonobos, 169 00:09:15,014 --> 00:09:18,225 that free love philosophy makes evolutionary sense. 170 00:09:18,309 --> 00:09:20,561 The males get to spread their seed 171 00:09:20,644 --> 00:09:23,939 and the females get to take in the seed of multiple males, 172 00:09:24,023 --> 00:09:26,817 which then compete against each other to fertilize her egg. 173 00:09:26,900 --> 00:09:29,903 It's survival of the fittest, for sperm. 174 00:09:29,987 --> 00:09:34,575 There are aspects of bonobo anatomy that seem adapted to promiscuity, 175 00:09:34,658 --> 00:09:38,579 and intriguingly, you can also find a lot of them in humans, 176 00:09:38,662 --> 00:09:42,249 suggesting we may have evolved to be non-monogamous, too. 177 00:09:42,333 --> 00:09:44,376 There's body dimorphism. 178 00:09:44,460 --> 00:09:47,171 In species that are more promiscuous, 179 00:09:47,254 --> 00:09:51,300 the males tend to be 15 to 25 percent larger than the females. 180 00:09:51,383 --> 00:09:54,470 And in theory, if there are males battling to impregnate women, 181 00:09:54,553 --> 00:09:57,389 testicles would be bigger and stronger. 182 00:09:57,473 --> 00:10:03,270 [Christopher Ryan] Human testicles are intermediate between very large testicles 183 00:10:03,354 --> 00:10:08,567 in bonobos and chimpanzees, and very small testicles in gorillas, for example. 184 00:10:08,651 --> 00:10:10,277 There's the human penis, 185 00:10:10,361 --> 00:10:14,573 tied for the biggest among all primates, which has a unique shape. 186 00:10:14,657 --> 00:10:18,035 We have this much thicker penis with the flared head. 187 00:10:18,118 --> 00:10:23,082 This shape creates a vacuum in the female's reproductive tract 188 00:10:23,165 --> 00:10:29,630 that tends to pull any sperm already there and pulls it down away from the ovum, 189 00:10:29,713 --> 00:10:35,344 thereby giving an advantage to the sperm of the man who's having sex at the moment. 190 00:10:35,427 --> 00:10:38,764 There's also female copulatory vocalization, 191 00:10:38,847 --> 00:10:41,308 a phenomenon so well-known and accepted, 192 00:10:41,392 --> 00:10:44,436 it's a standard feature of movie sex scenes. 193 00:10:44,520 --> 00:10:48,774 [groaning and screaming] 194 00:10:48,857 --> 00:10:52,820 What we see is that female copulatory vocalization is common 195 00:10:52,903 --> 00:10:56,031 among primates that engage in sperm competition. 196 00:10:56,115 --> 00:10:59,493 Then there's the fact that humans and bonobos have sex to bond. 197 00:10:59,576 --> 00:11:01,036 And not just to have children. 198 00:11:01,120 --> 00:11:04,373 Which might explain the way we face each other during intercourse. 199 00:11:04,790 --> 00:11:09,670 You see humans and bonobos are the only two that face each other while having sex. 200 00:11:09,753 --> 00:11:13,173 And why we have a lot more of it than most mammals. 201 00:11:13,257 --> 00:11:16,593 So, clearly when people say 202 00:11:16,677 --> 00:11:19,179 so-and-so had sex like an animal, they're getting it backwards. 203 00:11:20,264 --> 00:11:24,309 And there's now a lot of evidence that monogamy is a more recent invention 204 00:11:24,393 --> 00:11:26,019 than most of us would expect. 205 00:11:26,103 --> 00:11:28,063 Around 12,000 years ago, 206 00:11:28,147 --> 00:11:30,190 when most humans stopped being hunter-gatherers 207 00:11:30,274 --> 00:11:31,775 and figured out how to farm. 208 00:11:34,278 --> 00:11:40,367 You get a very overpowering concern with property rights. 209 00:11:40,451 --> 00:11:45,706 As the Greeks put it, you don't want a foreign seed introduced into your soil. 210 00:11:45,789 --> 00:11:51,420 For thousands of years, marriage was the way to increase your family labor force. 211 00:11:51,503 --> 00:11:54,465 You made peace treaties, business alliances... 212 00:11:54,548 --> 00:11:59,428 The more I've studied, the more I became convinced that marriage was invented 213 00:11:59,511 --> 00:12:03,056 not to do with the individual relationship with a man and a woman 214 00:12:03,140 --> 00:12:04,349 but to get in-laws. 215 00:12:04,433 --> 00:12:08,228 You know, and it's amusing because today we see in-laws as the big threat 216 00:12:08,312 --> 00:12:10,814 to the solidarity of the man and the woman. 217 00:12:10,898 --> 00:12:12,775 But that's what marriage was about. 218 00:12:12,858 --> 00:12:16,862 You look back at Anthony and Cleopatra, that was not a love story at all. 219 00:12:16,945 --> 00:12:21,074 That was two people from the most powerful empires in the world 220 00:12:21,158 --> 00:12:25,329 trying to figure out how they could get together and rule both of those empires. 221 00:12:25,412 --> 00:12:28,791 The idea of marrying someone for love, 222 00:12:28,874 --> 00:12:33,170 Coontz says Western societies only started doing that a few hundred years ago. 223 00:12:36,965 --> 00:12:42,554 As we made a transition to the idea that marriage should be on the basis of love, 224 00:12:42,638 --> 00:12:44,181 it scared people. 225 00:12:44,264 --> 00:12:47,267 Defenders of traditional marriage said, "Oh, my gosh. 226 00:12:47,351 --> 00:12:51,438 How will we get a woman to marry at all if she says, 'Eww, I don't love him.' 227 00:12:51,522 --> 00:12:54,608 How will we stop people from getting divorced?" 228 00:12:55,025 --> 00:12:57,069 So a new idea took hold. 229 00:12:57,152 --> 00:13:00,072 Men and women needed to find love and marry 230 00:13:00,155 --> 00:13:02,449 because they were two parts of a whole. 231 00:13:02,533 --> 00:13:04,284 Men were aggressive and protective, 232 00:13:04,368 --> 00:13:06,620 women were nurturing and demure. 233 00:13:06,745 --> 00:13:09,248 They were opposites who completed each other. 234 00:13:10,290 --> 00:13:13,919 The field of evolutionary biology also developed around this time, 235 00:13:14,002 --> 00:13:16,004 pioneered by male scientists 236 00:13:16,088 --> 00:13:21,176 who used theories on sexual selection to explain Victorian gender roles. 237 00:13:21,844 --> 00:13:24,513 As Charles Darwin wrote in The Descent of Man: 238 00:13:41,738 --> 00:13:44,992 And it's possible his ideas became so popular 239 00:13:45,075 --> 00:13:47,744 and survived so long because it made sense to us 240 00:13:47,828 --> 00:13:50,330 in the societies we were living in. 241 00:13:50,414 --> 00:13:54,001 But if monogamy is all a made-up construct, 242 00:13:54,084 --> 00:13:57,254 a way to enforce gender roles and social order, 243 00:13:57,337 --> 00:14:01,466 how do we explain that visceral, deep-rooted feeling we get 244 00:14:01,550 --> 00:14:02,968 when our loved ones stray? 245 00:14:03,051 --> 00:14:06,054 Tell me something. Are you the jealous type? 246 00:14:06,680 --> 00:14:11,393 I feel like we don't really deal too much with jealousy. 247 00:14:11,894 --> 00:14:14,187 I... I don't know why that is. 248 00:14:14,271 --> 00:14:16,356 -What it is... -It's because we're sluts. 249 00:14:16,440 --> 00:14:20,110 -To be honest. -I don't get, like, jealous like that. 250 00:14:20,193 --> 00:14:25,782 It's important to understand why you're feeling jealous because jealousy is not-- 251 00:14:25,866 --> 00:14:29,202 It's not a feeling, it's usually rooted in some other sort of thing. 252 00:14:29,286 --> 00:14:33,999 It's not a descending guillotine. It's like jealousy is an event. 253 00:14:34,082 --> 00:14:36,126 What's the best way to deal with that event? 254 00:14:36,877 --> 00:14:42,382 Who were you really with? That little blonde secretary from the office? 255 00:14:42,466 --> 00:14:46,803 I don't think you'll ever find any society where there was no sexual jealousy, 256 00:14:46,887 --> 00:14:51,934 but we also have these other kinds of impulses of generosity 257 00:14:52,017 --> 00:14:55,812 and of a sense that maybe there are other parts of the person 258 00:14:55,896 --> 00:14:58,899 that are more important than the sexual person. 259 00:14:58,982 --> 00:15:02,486 And these coexist and they battle and I think they will always battle. 260 00:15:02,569 --> 00:15:05,113 I say monogam-ish to describe my relationship with my husband. 261 00:15:05,197 --> 00:15:09,660 We've been together for 24 years, and not monogamous for 20 of those years. 262 00:15:09,743 --> 00:15:13,246 And I've had people look at me and say, "I could never do what you guys do 263 00:15:13,330 --> 00:15:15,374 because I value commitment too highly. 264 00:15:15,457 --> 00:15:18,168 All three of my marriages were monogamous." 265 00:15:18,251 --> 00:15:22,047 This person was committed to monogamy, not to any of the people they married, 266 00:15:22,130 --> 00:15:23,590 they were committed to monogamy. 267 00:15:23,674 --> 00:15:27,219 Non-monogamy is getting more mainstream attention. 268 00:15:27,302 --> 00:15:29,304 -Define polyamorous. -Without monogamy. 269 00:15:29,388 --> 00:15:30,973 -Polyamory... -Polyamory... 270 00:15:31,056 --> 00:15:33,141 -Polyamorous. -It's called polyamory. 271 00:15:33,266 --> 00:15:34,810 -Polyamorous people. -Threeple. 272 00:15:34,893 --> 00:15:37,062 -Non-monogamous, okay? -You couldn't be. 273 00:15:37,604 --> 00:15:40,941 A 2016 study found one in five Americans 274 00:15:41,024 --> 00:15:44,111 have been in a non-monogamous relationship at some point. 275 00:15:44,194 --> 00:15:48,198 And in another survey, a third of Americans said their ideal relationship 276 00:15:48,281 --> 00:15:50,075 would be non-monogamous. 277 00:15:50,158 --> 00:15:54,079 Monogamy as we know it has been through many incarnations. 278 00:15:54,496 --> 00:15:55,998 It's been forced. 279 00:15:56,081 --> 00:15:57,332 It's been useful. 280 00:15:57,416 --> 00:15:58,500 It's been beautiful. 281 00:15:58,583 --> 00:16:00,419 It's been subverted. 282 00:16:00,502 --> 00:16:02,337 As human society evolves, 283 00:16:02,421 --> 00:16:03,964 so will human sexuality. 284 00:16:04,047 --> 00:16:07,843 As we enter what I think of as uncharted territory, 285 00:16:07,926 --> 00:16:09,845 for the first time in human history, 286 00:16:09,928 --> 00:16:13,974 we're trying to develop relationships that are not based on coercion. 287 00:16:14,057 --> 00:16:17,185 Coercion of women by their economic and legal dependence, 288 00:16:17,269 --> 00:16:19,021 coercion of women by their bodies, 289 00:16:19,104 --> 00:16:22,566 coercion of men by the social and economic structures. 290 00:16:22,649 --> 00:16:25,152 We're trying, I think, to find maybe a new balance. 291 00:16:25,235 --> 00:16:26,737 Monogamy isn't natural. 292 00:16:27,112 --> 00:16:30,282 It means we have to recognize that, because it's not natural, 293 00:16:30,741 --> 00:16:34,453 it's something that we're going to have to work for if we want it. 294 00:16:34,578 --> 00:16:39,291 One of the things that I think makes human beings particularly interesting, 295 00:16:39,374 --> 00:16:42,377 and maybe even unique in the animal world, 296 00:16:42,461 --> 00:16:46,256 is that we're capable of doing things that are unnatural. 297 00:16:46,631 --> 00:16:48,717 Monogamy is like vegetarianism. 298 00:16:48,800 --> 00:16:52,596 You can choose to be a vegetarian and that can be healthy. 299 00:16:52,679 --> 00:16:55,140 It can be ethical, it can be a wonderful decision, 300 00:16:55,223 --> 00:16:58,477 but because you've chosen to be a vegetarian 301 00:16:58,560 --> 00:17:01,438 doesn't mean that bacon stops smelling good. 302 00:17:01,521 --> 00:17:02,689 If we're lucky, 303 00:17:02,773 --> 00:17:06,485 it's no longer about what kinds of relationships we should have 304 00:17:06,568 --> 00:17:08,070 in the modern world. 305 00:17:08,153 --> 00:17:11,907 It's about designing the kinds of relationships we want to have. 306 00:17:12,532 --> 00:17:15,702 Humans may not have evolved to be sexually monogamous,
