Revision with unchanged content. Survival of a species can be sub-divided into two main categories that determine everything. These categories, simply put, are food and sex; or, the need for all species to consume and reproduce. When political theorists focus on a problem, they focus on the consumption variable in its various forms as it relates to civilization, like poverty. Very few focus on the need for a species to reproduce in order to survive, or that reproduction is politically important. Gender Relations can be used in a new way to study mating systems across the planet, and can formulate a theory that unlocks the mysteries of political phenomenon. This book seeks the answer to one fundamental question: Under what conditions will sub-state actors turn to political violence or terrorism? Combining social science research in various fields of study including archeology, anthropology, history, political science, psychology, and sociology, this book develops a unique approach that attributes the development of political discourse to changes within a gendered system. Unlike previous theories of terrorism that connect discourse to authoritarianism, brainwashing, or inequalities in economics, gender relations are argued to be the essential key between war and peace.
