The Dangerous Passion: Why Jealousy Is as Necessary as Love and Sex

Why do men and women cheat on each other? How do men really feel when their partners have sex with other men? What worries women more -- men who turn to other women for love or men who simply want sexual variety in their lives? Can the jealousy husbands and wives experience over real or imagined infidelities be cured? Should it be? In this surprising and engaging exploration of men's and women's darker passions, David Buss, acclaimed author of The Evolution of Desire, reveals that both men and women are actually designed for jealousy. Drawing on experiments, surveys, and interviews conducted in thirty-seven countries on six continents, as well as insights from recent discoveries in biology, anthropology, and psychology, Buss discovers that the evolutionary origins of our sexual desires still shape our passions today. 

According to Buss, more men than women want to have sex with multiple partners. Furthermore, women who cheat on their husbands do so when they are most likely to conceive, but have sex with their spouses when they are least likely to conceive. These findings show that evolutionary tendencies to acquire better genes through different partners still lurk beneath modern sexual behavior. To counteract these desires to stray --

The Dopaminergic Mind In Human Evolution And History

What does it mean to be human? There are many theories of the
evolution of human behavior which seek to explain how our brains
evolved to support our unique abilities and personalities. Most of these
have focused on the role of brain size or specific genetic adaptations of
the brain. In contrast, Fred Previc presents a provocative theory that
high levels of dopamine, the most widely studied neurotransmitter,
account for all major aspects of modern human behavior. He further
emphasizes the role of epigenetic rather than genetic factors in the rise
of dopamine. Previc contrasts the great achievements of the dopaminergic
mind with the harmful effects of rising dopamine levels in
modern societies and concludes with a critical examination of whether
the dopaminergic mind that has evolved in humans is still adaptive to
the health of humans and to the planet in general.
Fred H. Previc is currently a science teacher at the Eleanor Kolitz
Academy in San Antonio, Texas. For over twenty years, he was a
researcher at the United States Air Force Research Laboratory where
he researched laser bioeffects, spatial disorientation in flight, and

The Evolution of Morality and Religion

Accepted codes of conduct and established religions are features of human societies throughout the world. Why should this be? In this book, biologist Donald Broom argues that these aspects of human culture have evolved as a consequence of natural selection; that morally acceptable behaviour benefits humans and other animals and that a principal function of religion is to underpin and encourage such behaviour. The author provides biological insights drawn especially from work on animal behaviour and presents ideas and information from the fields of philosophy and theology to produce a thought-provoking, interdisciplinary treatment. Scientists who read this book will gain an appreciation of the wider literature on morality and religion, and non-scientists will benefit from the author’s extensive knowledge
