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 getti...more

UPDATE #2: "Not since the Holy Bible has any book so misunderstood the process that created human beings." – Robert Wright.

Though the above quote was said half-jokingly, it sums things up quite nicely (if you can forgive the hyperbole). These were some of the last words in a videoconference between Robert Wright and Christopher Ryan. Click here to watch this conversation via bloggingheads. I just finished watching it, and it was well worth the time. As I mentioned in my initial review below, I n...more

I loved this book, but to be honest I have nowhere near the education to be able to evaluate the validity of the arguments presented in the book. I have seen grumblings here and there about the book, mostly from religious people who this book will understandably offend.

One of the main messages of the book is that monogamy is not natural to either men or women.

The authors are two researchers and psychologists, both married.

Despite being academics and approaching a variety of very weighty subjects...more

Hey! Hey, baby, baby, waitwaitwaitwait. Wait. Wait! Baby, don't... don't freak out

Okay, okay, I know what this looks like, but I can explain! Quiet, Chad, let me handle this. I can explain! I'm just - please, stop crying and listen - I'm just fulfilling my evolutionary heritage and helping to cement social bonds with... um... the pizza boy, but that'snotthepoint!! That's
not the point! Look, before you do anything, y'know, drastic, you just need to read this book....

Fantastic--

This is one of those paradigm-shifting books that pretty much changes your belief system. Having read Robin Baker's Sperm Wars and absorbing its grim interpretation of human sexuality, this book, Sex at Dawn came as a pleasant and generally kick-ass surprise.

With abundance of humor and compelling narrative, the authors posit that human beings, like their primate cousins, originally engaged in multiple mating for most of their existence on earth before the advent of agriculture. And "m...more

I heard Ryan interviewed on the podcast "Sex Nerd Sandra", was intrigued by his novel ideas, and decided to pick up the book. The overarching argument is that men and women were not historically monogamous the way society and many scientists claim. They back up this with physical and behavioral evidence from our close cousins, the chimp and bonobo, and from the information we have about prehistoric human societies and existing hunter-gatherers.

The authors are also somewhat avowed neo-Rousseauns...more

Should I read it? Yes, yes, yes! You shouldn't even bother with this review! Just go read the book!

What's the short and skinny of it?
From the first few chapters, readers are introduced to the questions Sex at Dawn seeks to answer: "Why do we have the urges and anatomies we do, and what do these things say of our evolution? Are the cultural narratives we're taught about sexuality and marriage based on science? Do we work against nature because of culture? How did we develop the ideas we have abou...more
Nancy Rector
Phenomenal mind opening book about the true origins of our societies typical view of sex and monogamy. Also delves into the topics of war and jealousy and if those are indeed innate traits of humans. The facts show they are not. As with many beliefs that are just mindlessly accepted by so many people this points out that many things are not what they seem. And that we as a people need to have the courage and strength to think for ourselves and to continually question and learn for ourselves.

A long time ago, in a galaxy far away, I was an anthropology major at UCSC. Although I wanted to specialize in physical anthropology, I did quite a bit of classwork in cultural. One of the things that always fascinated me was fictitious kin. The idea of creating a network of ties to promote sharing among small groups. Church congregations and the scooby gang of Joss Whedon's Buffy are examples of this. I found the author's description of several of these types of kinship networks based on common...more

This is a fascinating and well researched view into how humans became the highly sexual creatures we are today. It flips the outdated and poorly proven Hobbes theory--that we were brutish, impoverished, war torn prehistoric animals--on its head. Instead, it offers compelling evidence and astute observations that for 90% of our 2.5 million years on Earth, humans basically had enjoyable sex with each other all day (multiple partners) and ate nutritious food from the earth without war and without m...more

A popularizer's polemic against evolutionary psychology vis-a-vis the doctrine and institution of monogamy. The book is well-humored, and the prose reads well.

The broad strokes of the argument are difficult to dispute, and I wouldn't want to dispute them. Monogamy earned this ass-kicking--and it is an ass-kicking, a true shellacking, considering the data marshalled in support, as well as the motion-for-summary-judgment style of pointing out a lack of support for the opponent's essential allegat...more

This book makes one depressed about the human race from agriculture on. However, it kind of awesomely doesn't make me feel like a slut, proving (through science!) how our anatomy developed and how we, as humans, were made to have sex with many different people. Sometimes all at once. With chocolate sauce. Kidding about the chocolate sauce.

Really, the book goes over our closest relatives, and then discusses common beliefs about the human race, and proves or disproves some of those beliefs. It's p...more

Controversial. Probably a number of correct points concerning the real evolution of human sexuality from the hunter gatherer society and the failures of current models of human sexuality to recognize we are more like bonobos than chimpanzees or gibbons. Its main conclusion, however, that marital monogamy is losing proposition, with evolutionary biology and genetic disposition pushing against it may have some merit. But the books solution seems out of touch with the reality of contemporary Wester...more

Pomo Feminists and queer theorists beware! You might not like this. This book makes a strong and rather compelling case that there is a biological functionalism to our sexuality: namely sex for bonding and social harmony first and procreation second. The vast majority of the book is outlining the "essence" of male and female sexuality, making this a dissonance-causing book for anyone advocating criticism of gender essentialism and nonmonogamy simultaneously. Also it is about as snarky as Vice Ma...more
Juliana
Note: this would be a much better review if I hadn't read the book months ago. Mixed feelings. I think they present some credible evidence that humans may be rather more like bonobos than like our other primate cousins, and that monogamy is far from the only possibility (or even the norm) for many animals, and that it's not the norm in many human cultures. And they do pick apart some of the more heinously implausible evolutionary psychology theories about human sexuality. That being said, they c...more

The right mix of popular science and snark. It's like mix of Frans De Waal's "Our Inner Ape", Jared Diamond's "Guns, Germs and Steel"(but for sex) and "The Third Chimpanzee", Frederich Engels "Origins of the Family, Private Property, and the State", Dan Savage's "Savage Love", Laura Kipnis' "Against Love", Dossie Easton and Catherine A. Liszt's "Ethical Slut" (but without the hippie vibe).

It combines many studies and articles I've been reading and taking note of for years, such as:

This is a topic that modern society has been wrestling with for ages. Well packaged in an easy to read book, Christopher Ryan presents a large amount of experimental, anatomical, and anthropological studies with a logical narrative of the evolution of human sexuality. He deals rather fairly with monogamy (remarking that the alternatives are not for everyone), even though it is clear that the bulk of the data is pointing toward a different human nature.

Although the topic is relevant to modern so...more

If homo sapiens are biologically wired for monogamy, why are we so bad at it? Authors Ryan and Jethá explore this question with intelligence, rigor, and wit. Through a critical review of social science research over the past 150 years, they argue our standard cultural narrative about pair bonding, sexual response, and female empowerment has at times clouded rigorous scientific inquiry and often contradicts prehistoric biological evidence. This book is eminently readable, and especially poignant...more

I've already had an a-ha! moment on every other page. This is exactly what I was missing in all of those evolutionary psychology classes where the rule was the following:

"Men are jealous, deceitful pigs who want to nail as many women as possible. Women put out only to manipulate men into supporting their children, and cuckold their partners with men with square jaws every time they ovulate, because they magically know when that is, and they aren't jealous of their men cheating on them as long a...more

I feel completely cheated...

This review is directed more towards people who have already read Sex at Dawn, and to the authors. But hopefully this will be of use to new readers as well.

I'll start by saying that when I first read Sex at Dawn I was blown away. This book completely changed my view of monogamy, sex, and relationships. It sparked this new openness and acceptance in me, and I will say had a very positive impact on my relationship. I thought here was the book that everyone NEEDS to read...more

Dan Savage kept making this sound like an epiphany of morals and sexual understanding. And while it is an interesting take on where our physical selves may have evolved from -- and may likely still have synergies with certain strains of primate -- it does what so many non-fiction books do, filling space with detours into interesting but not necessarily completely relevant factual material. The authors make a good case for the sexual issues our society may have developed from becoming agricultura...more

Picking this up, I thought "ok, I get it: people are not designed, genetically, to be monogamous - the idea of for-life bonding with just one person is culturally created for a whole bunch of reasons. But how on earth are the authors going to hold my attention for 400 pages with this one idea?" - they do, and then some. Sure, the authors decimate the idea of monogamy being the natural order of things, but they also poke big holes in the idea of the superiority of agrarian society, showing up the...more

This book really seems to elicit some strong opinions and have a sneaking suspicion that people are dividing up by whether the book validates or invalidates some strongly held belief. It's either "This is bad science, it's poorly researched and patently untrue" or "this book is scientifically brilliant and incredibly well researched". I am not a scientist nor do I play one on TV so I am probably not qualified to remark one way or another on the quality of the scientific research other than to sa...more

Evolutionary biology and sexual biology are fascinating topics, and when we look at the history of the human species, it's even more interesting to consider our human origins or more specifically our pre-human ancestors. This book goes into great depth discussing the most likely explanations for the sexual biology of our species based on other primates that are also our closest genetic neighbors (namely Bonobos). By looking at the sexual dimorphism of our species, male sperm production, male and...more

I rarely stop reading books before I'm done (and I've read a lot of pretty bad books as a result!), but I think I will with this one. The book has two serious problems: first, it misrepresents (or maybe misunderstands?) the standard model of human sexuality from ev. biology. Perhaps because they are so focused on the most extreme form of ev. psych, they repeatedly oversimplify things, and then accuse various authors (e.g., Darwin) of defending such oversimplified theories because of sexism. Seco...more

1) Cacilda Jetha is co-author, but not listed in Goodreads-- Goodreads didn't believe a [possibly] woman would embrace sex at dawn? what is that all about?

Reading the book, it seemed that the authors, a la Lionel Tiger, and the aggression guy who claims we were born with our dukes up [?], were very eager to find good evidence for un-regulated sex in pre-history; further were enjoying being provocative and shibboleth-lancing.

Reading a review of "Sex at Dusk" [that's THE book to read], sounds li...more

Thought-provoking and funny, what I appreciated most is how this book challenges the dominant narratives in evolutionary psychology about male dominance, warfare and sex. I'm not an expert nor am I well-read in evolutionary psychology so I can't attest to how accurate this book is in its research, but it does capture several cultural notions well, especially that sexuality is a destructive force that must be controlled on both sides (but particularly for women). It presents evidence to the contr...more

A Review by Anthony T. Riggio of Sex at Dawn by Christopher Ryan and Cacilda Jetha

This book was recommended on a list server I subscribe to, by someone whose intelligence I held in high esteem.

Upon receiving my hard bound book from Amazon, I could not wait to get into the premise of this book, namely the study of our evolutionary biological ancestors and their untempered behaviors. Let me preface my comments by stating that I am a Christian but a believer in the evolutionary appearance of man on...more

This book... UGH. It's starts off talking about bonobos bonobos bonobos! The forgotten cousin who boinks all the time in a free-loving society! And of which there seems to be little actual study! It's great to point out that our genetic closeness to this group has been overlooked, but I would like some more scientific evidence cited here, especially before their exclusion in accounts of human sexuality gets mentioned over and over and over again. Also, maybe all those studies that fail to mentio...more

There is much debate about the "scientific-ness" of this book, however, it's most important quality is that it asks the reader to question everything that was once held as truth (standard narrative). The authors provide an extensive list of notes and further reading at the end for those that wish to delve further into the topics addressed. Every social science study or theory will naturally be biased within its cultural context -- Darwin, Freud, and the authors of this book. The book does not at...more

I liked the informal comedic writing style although at times the sarcasm is seething. I'm sure the writer became aware of how condescending he was towards some prominent people. The book seems very opinionated and not very informed until somewhere around the middle, where you find more factual backup to the arguments. The only reason I gave it 4 stars instead of 5 is because you really have to hold on a little longer until he starts convincing you. The content itself is very informative, and eve...more

“And yet, despite repeated assurances that women aren't particularly sexual creatures, in cultures around the world men have gone to extraordinary lengths to control female libido: female genital mutilation, head-to-toe chadors, medieval witch burnings, chastity belts, suffocating corsets, muttered insults about "insatiable" whores, pathologizing, paternalistic medical diagnoses of nymphomania or hysteria, the debilitating scorn heaped on any female who chooses to be generous with her sexuality...all parts of a worldwide campaign to keep the supposedly low-key female libido under control. Why the electrified high-security razor-wire fence to contain a kitty-cat?” 19 people liked it
“Marriage," "mating," and "love" are socially constructed phenomena that have little or no transferable meaning outside any given culture. The examples we've noted of rampant ritualized group sex, mate-swapping, unrestrained casual affairs, and socially sanctioned sequential sex were all reported in cultures that anthropologists insist are monogamous simply because they've determined that something they call "marriage" takes place there. No wonder so many insist that marriage, monogamy, and the nuclear family are human universals. With such all-encompassing interpretations of the concepts, even the prairie vole, who "sleeps with anyone," would qualify.” 15 people liked it
