Since Darwin's day, we've been told that sexual monogamy comes naturally to our species. Mainstream science—as well as religious and cultural institutions—has maintained that men and women evolved in families in which a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married, and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages. How can reality be reconciled with the accepted narrative? It can't be, according to renegade thinkers Christopher Ryan and Cacilda Jethå. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book. Ryan and Jethå's central contention is that human beings evolved in egalitarian groups that shared food, child care, and, often, sexual partners. Weaving together convergent, frequently overlooked evidence from anthropology, archaeology, primatology, anatomy, and psychosexuality, the authors show how far from human nature monogamy really is. Human beings everywhere and in every era have confronted the same familiar, intimate situations in surprisingly different ways. The authors expose the ancient roots of human sexuality while pointing toward a more optimistic future illuminated by our innate capacities for love, cooperation, and generosity. With intelligence, humor, and wonder, Ryan and Jethå show how our promiscuous past haunts our struggles over monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for transient affairs with younger women; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality. In the tradition of the best historical and scientific writing, Sex at Dawn unapologetically upends unwarranted assumptions and unfounded conclusions while offering a revolutionary understanding of why we live and love as we do.

Since Darwin's day, we've been told that sexual monogamy comes naturally to our species. it doesn't, and it never has. Mainstream science-as well as religious and cultural institutions-have long maintained that men and women evolved in families where a man's possessions and protection were exchanged for a woman's fertility and fidelity. But this narrative is collapsing. Fewer and fewer couples are getting married and divorce rates keep climbing as adultery and flagging libido drag down even seemingly solid marriages. In Sex at Dawn: The Prehistoric Origins of Modern Sexuality, renegade researchers Christopher Ryan and Cacilda JethÁ debunk almost everything we 'think we know' about sex while offering a bold alternative explanation for why we live and love as we do. With intelligence, humor, and wonder, Ryan and JethÁ show how our promiscuous past haunts our current struggles regarding monogamy, sexual orientation, and family dynamics. They explore why long-term fidelity can be so difficult for so many; why sexual passion tends to fade even as love deepens; why many middle-aged men risk everything for an affair; why homosexuality persists in the face of standard evolutionary logic; and what the human body reveals about the prehistoric origins of modern sexuality.

Sex – just what is it all about? Don't other species just get on with it? What are the conflicts and jealousy, pain and disappointments, really all about? The 2010 book SEX AT DAWN tells us that this modern misery is due to our belief in a false evolutionary story about human pair-bonding and nuclear family units. Christopher Ryan and Cacilda Jethá claim that their evidence shows that before 10,000 years ago sexual constraints did not exist, paternity was not an issue, and men and women engaged in fairly free and casual bonobo-like sexual activity. Our ancestors, they argue, not only shared food, they shared sex.Are they right?Using predominantly the same sources, SEX AT DUSK takes another look at that evidence, fills in many gaps, makes many corrections, and reveals something far less candy-coated. Bringing together evolutionary biology, primatology, anthropology, and human sexuality, SEX AT DUSK shows that, rather than revealing important facts about our sexual evolution, Sex at Dawn shrouds it in a fog of misinformation and faulty logic that can only lead us further into the dark.

A fascinating insight into how human sexuality came to be the way it is now - Jared Diamond explains why we are different from the animal kingdom. Why are humans one of the few species to have sex in private? Why do humans have sex any day of the month or year, including when the female is pregnant, beyond her reproductive years, or between her fertile cycles? Why are human females one of the few mammals to go through menopause? Human sexuality seems normal to us but it is bizarre by the standards of other animals. Jared Diamond argues that our strange sex lives were as crucial to our rise to human status as were our large brains. He also describes the battle of the sexes in the human and animal world over parental care, and why sex differences in the genetic value of parental care provide a biological basis for the all-too-familiar different attitudes of men and women towards extramarital sex.

“With . . . evidence from recent genetic and anthropological research, [Zuk] offers a dose of paleoreality.”—Erin Wayman, Science News We evolved to eat berries rather than bagels, to live in mud huts rather than condos, to sprint barefoot rather than play football—or did we? Are our bodies and brains truly at odds with modern life? Although it may seem as though we have barely had time to shed our hunter-gatherer legacy, biologist Marlene Zuk reveals that the story is not so simple. Popular theories about how our ancestors lived—and why we should emulate them—are often based on speculation, not scientific evidence. Armed with a razor-sharp wit and brilliant, eye-opening research, Zuk takes us to the cutting edge of biology to show that evolution can work much faster than was previously realized, meaning that we are not biologically the same as our caveman ancestors. Contrary to what the glossy magazines would have us believe, we do not enjoy potato chips because they crunch just like the insects our forebears snacked on. And women don’t go into shoe-shopping frenzies because their prehistoric foremothers gathered resources for their clans. As Zuk compellingly argues, such beliefs incorrectly assume that we’re stuck—finished evolving—and have been for tens of thousands of years. She draws on fascinating evidence that examines everything from adults’ ability to drink milk to the texture of our ear wax to show that we’ve actually never stopped evolving. Our nostalgic visions of an ideal evolutionary past in which we ate, lived, and reproduced as we were “meant to” fail to recognize that we were never perfectly suited to our environment. Evolution is about change, and every organism is full of trade-offs. From debunking the caveman diet to unraveling gender stereotypes, Zuk delivers an engrossing analysis of widespread paleofantasies and the scientific evidence that undermines them, all the while broadening our understanding of our origins and what they can really tell us about our present and our future.

Somewhere, somebody is having more fun than you are. Orso everyone believes. Peter Sagal, a mild-mannered, Harvard-educated radio host—the man who puts the second "l" in "vanilla"—decided to find out if it's true. From strip clubs to gambling halls to swingers clubs to porn sets and back to the strip clubs (but only because he left his glasses there), Sagal explores what the sinful folk do, how much they pay for the privilege, and how exactly they got those funny red marks.
