Book Summary: Sex at Dawn by Christopher Ryan and Cacilda Jethá

Sex at Dawn by Christopher Ryan and Cacilda Jethá Book Cover

Sex at Dawn is a groundbreaking book that challenges the conventional view of human sexuality. Written by Christopher Ryan and Cacilda Jethá, the book explores the idea that human beings are not naturally monogamous and that our ancestors lived in egalitarian, polyamorous societies. The authors argue that the dominant monogamous paradigm is outdated and does not accurately reflect the nature of human sexuality.

In the first chapter, the authors debunk the myth of monogamy and argue that it is not a natural or universal human trait. They cite evidence from anthropology, primatology, and evolutionary biology to show that monogamy is rare in the animal kingdom and that human societies throughout history have been characterized by polygamy, polyandry, and group marriage.

Chapter 2: The Evolution of Desire

In the second chapter, the authors explore the evolutionary origins of human sexuality. They argue that human desire is shaped by a complex interplay of genetic, environmental, and cultural factors, and that our ancestors’ sexual behavior was shaped by the need to reproduce and the desire for pleasure.

Chapter 3: The Myth of the Forbidden Fruit

In the third chapter, the authors challenge the idea that monogamy is the natural outcome of sexual jealousy. They argue that jealousy is a cultural construct that has been used to enforce monogamy in many societies, and that our ancestors may have viewed jealousy as a negative emotion that was best avoided.

Chapter 4: The Myth of the Cuckold

In the fourth chapter, the authors debunk the myth of the cuckold, or the male whose partner has been unfaithful. They argue that the fear of cuckoldry has been used to enforce monogamy in many societies, but that there is no evidence to suggest that cuckoldry was a common occurrence in our ancestors’ societies.

Chapter 5: The Myth of Paternity

In the fifth chapter, the authors explore the idea that paternity is a social construct that has been used to enforce monogamy. They argue that our ancestors may have viewed paternity as a social construct that was best left undefined, and that the idea of the nuclear family may be a recent invention.

Chapter 6: The Myth of Romantic Love

In the sixth chapter, the authors challenge the idea that romantic love is a natural and universal human emotion. They argue that romantic love is a cultural construct that has been used to enforce monogamy, and that our ancestors may have viewed love as a positive emotion that was best shared with multiple partners.
