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.

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.

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.

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....

Binary is the ultimate guide for understanding and dismantling the sex spectrum, the new cultural belief that sex exists on a continuum and that male and female are social constructs. By analyzing its 10 most popular arguments, Zachary A. Elliott reveals how the tenets of the sex spectrum deny evolution, development, and genetics. Using the primary biology literature, the book provides the listener with a comprehensive scientific understanding of how the two sexes are universal phenomena and how complex genetic networks consistently result in a simple yet profound outcome: male or female.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

In Strange Bedfellows, David P. Barash and Judith Eve Lipton look at how biology actually promotes monogamy in some species and how these lessons apply to human beings. An accessible work of science that is relevant to our intimate daily life, Strange Bedfellows will reassure some people, surprise others, and engage everyone.
