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 Jethá. While debunking almost everything we "know" about sex, they offer a bold alternative explanation in this provocative and brilliant book.

Ryan and Jethá'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 Jethá 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.

Gaia theory argues that the flora and fauna of the planet operate in a self-regulating web that keeps the world livable. According to the theory, humankind is the most powerful species in this web and also its biggest threat. This provocative book explores ways to minimize and ultimately eliminate this threat with love and intimacy.

Controversial Italian author Serena Anderlini-D’Onofrio has authored the first global ecology study based on an analysis of human health. Anderlini-D’Onofrio identifies her remedy within the context of Gaia theory, re-envisioning it as a more inclusive philosophy that positively impacts not only relationships but world ecology under duress.

The author links human sexuality to the global ecosystem, claiming that freedom from fear will stimulate a holistic health movement powerful enough to heal relationships and restore planetary balance.

Gaia and the New Politics of Love is bracing in its range, weaving together issues of human and global health; the relationship of politics, sexuality, and ecology; practices and styles of love; the changing roles of eroticism and gender in our lives; and polyamory, bisexuality, and the AIDS reappraisal movement.

The argument of this book emphasizes the arts of loving as a way to help humanity make peace with our hostess Gaia, the third planet. Some of these arts involve sharing emotional resources and amorous partners. Often, the arts of loving require the use of barriers: mechanical protections such as condoms. At times they do not because only tantric energies are exchanged.

The author of this book is persuaded that barriers are recommendable when sexual practices result in the exchange of deep body fluids, unless previous fluid-bonding arrangements have been made. The author is also persuaded that good practices of holistic health contribute to strengthening the immune systems of those who engage in the arts of loving.

Safety practices are important in making the arts of loving healthy regardless of what factors are involved in the syndromes most prevalent today, including AIDS and other conditions in the STD spectrum. Historically, disagreement has moved knowledge forward: Today’s science is the result of yesterday’s disagreements and controversies. The author believes in critical thinking and she respects dissidence in science today, including Gaia science, reappraisals of AIDS, and holistic medicine. She hopes her readers will be open to hearing more than one side of a story.
