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?

In this exploration of the concept of the gene, Jonathan Slack looks at the discovery, nature, and role of genes in both evolution and development. Explaining the nature of genetic variation in the human population, how hereditary factors were identified as molecules of DNA, and how certain specific mutations can lead to disease, Slack highlights how DNA variants are used to trace human ancestry and migration, and can also be used by forensic scientists to identify individuals in crime.

Minding the Climate investigates this problem in the neuroscience of decision-making. Ann-Christine Duhaime, MD, points to the evolution of the human brain during eons of resource scarcity. The brain adapted to prioritize short-term survival over more uncertain long-term outcomes. But the resulting behavioral architecture is poorly suited to the present, when scarcity is a lesser concern and slow-moving challenges like environmental issues present the greatest danger.

Since 2010 it has been possible to determine a person's genetic makeup in a matter of days at an accessible cost for many millions of people. Along with this technological breakthrough there has emerged a movement to use this information to help prospective parents "eliminate preventable genetic disease." As the prospect of systematically excluding the appearance of unwanted mutations in our children comes within reach, David B. Goldstein examines the possible consequences from these types of choices.

In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed - a toxic plant named for the sticky white substance emitted when its leaves are damaged - and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species.

From star-nosed moles that have super-sensing snouts to electric eels that paralyze their prey, animals possess unique and extraordinary abilities. In Great Adaptations, Kenneth Catania presents an entertaining and engaging look at some of nature's most remarkable creatures. Telling the story of his biological detective work, Catania sheds light on the mysteries behind the behaviors of tentacled snakes, tiny shrews, zombie-making wasps, and more.

Does human life have any meaning? Does the question even make sense today? For centuries, the question of the meaning or purpose of human life was assumed by scholars and theologians to have a religious answer: Life has meaning because humans were made in the image of a good god. In the 19th century, however, Charles Darwin's theory of evolution changed everything - and the human organism was seen to be more machine than spirit.

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.

We are all familiar with the "march of progress," the representation of evolution that depicts a series of apelike creatures becoming progressively taller and more erect before finally reaching the upright human form. Its emphasis on linear progress has had a decisive impact on public understanding of evolution, yet the image contradicts modern scientific conceptions of evolution as complex and branching.

Thousands of religions have adherents today, and countless more have existed throughout history. What accounts for this astonishing diversity? This extraordinarily ambitious and comprehensive book demonstrates how evolutionary systematics and philosophy can yield new insight into the development of organized religion. Lance Grande—a leading evolutionary systematist—examines the growth and diversification of hundreds of religions over time, highlighting their historical interrelationships.

In The Other Big Bang, the evolutionary and developmental biologist Eric S. Haag explores the two-billion-year history of sex, from the first organisms on Earth to contemporary humans.

Well-meaning physicians, parents, and even scientists today often spread misinformation about what biology can and can't tell us about our bodies, minds, and identities. In this accessible, myth-busting book, geneticist Shoumita Dasgupta draws on the latest science to correct common misconceptions about how much of our social identities are actually based in genetics.

Experts agree on the value of genetic testing when there is a family history of disease, or if the patient has an illness frequently caused by a mutation. Knowing the disease mutation lets family members find out if they have it too and need preventive care. The book explains that doctors can order tests with genetic counseling at relatively low cost and how this will help them prescribe preventive actions, make earlier diagnoses, and get better outcomes.
