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....

In The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and will Determine the Fate of the Human Race, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and more.

There is no one better qualified than Jared Diamond - renowned expert in the fields of physiology and evolutionary biology and award-winning author - to explain the evolutionary forces that operated on our ancestors to make us sexually different. With wit and a wealth of fascinating examples, he explains how our sexuality has been as crucial as our large brains and upright posture in our rise to human status. 

In this fascinating and thought-provoking book, author Nick Lane brings together the latest research findings in the exciting field of mitochondria research to reveal how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death. 

A podcast about the amazing and sometimes devious molecules behind life itself, the mind, sex and the cures of the future. It’s for literally anyone who’s curious if they don’t mind the occasional bit of wry humor mixed in with the serious stuff.

With acuity, humor, and respect for human diversity, The Shortest History of Sex reveals where the many facets of our sexuality—chemical, anatomical, behavioral, social—come from. Chasing down our evolutionary family tree, from the first aquatic creatures to primate societies, David Baker sheds light on our baffling array of passions, impulses, and fetishes, and guides us toward a clear understanding of one of the deepest, most abiding forces of human nature.

Being human entails an astonishingly complex interplay of biology and culture, and while there are important differences between women and men, there is a lot more variation and overlap than we may realize. Sex Is a Spectrum offers a bold new paradigm for understanding the biology of sex, drawing on the latest science to explain why the binary view of the sexes is fundamentally flawed.

Dive into Henry Stantons 1922 classic, Sex – Avoided Subjects Discussed in Plain English, a groundbreaking guide that tackles the complexities of human sexuality and relationships with a candid yet conservative lens. This book serves as both a self-help resource and a digestible exploration of the scientific understanding of sex and reproduction during its time. With clarity and purpose, Stanton aims to educate readers on these often-taboo topics, making them accessible for everyone. Join Carl Manchester as he narrates this enlightening journey through the nuances of human behavior and ...

Digital innovation has rapidly changed the landscape of sexual experience in the 21st century. Rules-based sexual ethics, subscribed to by many Christians, are unable to keep up with new developments and, more often than not, seem effective at little other than generating shame.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

Are humans unwitting partners in evolution with psychedelic plants? Darwin’s Pharmacy shows they are by weaving the evolutionary theory of sexual selection and the study of rhetoric together with the science and literature of psychedelic drugs. Long suppressed as components of the human tool kit, psychedelic plants can be usefully modeled as “eloquence adjuncts” that intensify a crucial component of sexual selection in humans: discourse.

A myth-busting vindication of women's physical strengths For decades, Starre Vartan - like most women - was told that having a woman's body meant being weaker than men. Like many women, she mostly believed it. Not anymore. Following a half decade of research into the newest science, Vartan shows...

Sex, after hunger, may be the most powerful motivating force in our lives. It drives us to seek intimate contact with others and to form relationships that may be fleeting or lifelong, blissful or troubled. Yet many mysteries surround sex and sexuality: Why don't we reproduce by virgin birth? Why does so much of our sexual behavior have nothing to do with reproduction? Why isn't everyone heterosexual? How does the brain create sexual arousal? How do sexual kinks develop? Is porn harmful? What is the relationship between sex and love?

Between what can be learned from evolutionary psychology and cognitive science a picture emerges. In Sex, Murder, and the Meaning of Life, social psychologist Douglas Kenrick fuses these two fields to create a coherent story of human nature. In his analysis, many ingrained, apparently irrational behaviors—one-night stands, prejudice, conspicuous consumption, even art and religious devotion—are quite explicable and (when desired) avoidable.

Sex - it's not just for humans! Dive into this wacky but scientific exploration of all things sex. Get answers to all of the random questions you might never have thought to ask yourself.

Just as humans procreate, animals have their own way of getting it on, too! Some ways are quite unexpected, from the cannibalistic mating practices of the praying mantis to the complicated sex life for snails with backwards organs.

In the years after World War II, the airline stewardess became one of the most celebrated symbols of American womanhood. Stewardesses appeared on magazine covers, on lecture circuits, and in ad campaigns for everything from milk to cigarettes. Airlines enlisted them to pose for publicity shots, mingle with international dignitaries, and even serve (in sequined minidresses) as the official hostesses at Richard Nixon's inaugural ball. Embodying mainstream America's perfect woman, the stewardess was an ambassador of femininity and the American way both at home and abroad.

Vital research is starting to challenge long-standing assumptions about gender identity and biological sex, such as work that indicates the brain is a “mosaic” of traits rather than a “male” and “female” brain. Growing knowledge of the genetic complexities of sexual determination is changing the way the medical community treats intersex individuals, and in this audiobook, The New Science of Sex and Gender, we not only examine the latest studies in biology, medicine, and psychology but also, more importantly, their bearing on healthcare, identity, and access. 

Few of us know much about the biology of sex determination, but what could be more interesting than to discover how we are shaped into males and females? In this book, Elof Carlson tells the incredible story of the difficult quest to understand how the body forms girls and boys. Carlson's history takes us from antiquity to the present day to detail how each component of human reproduction and sexuality was identified and studied....
