Sexual Motivation

Sexual motivation refers to a person's overall desire for sexual activity. It is an unusual motivation. Generally, among lower animals, the term 'drive' is commonly referred to as sexual motivation. It means a certain internal force drags the animal to be involved in reproductive behavior. On the contrary, humans are not simply driven by any internal force; rather, the sexual motivation in humans is due to several factors such as biological (hormones, genes), environmental (familial upbringing, chemical exposure) and physiological factors (culture, desire) which further determine engagement in sexual activities.

1. Early hunter-gatherers were interbreeding with colonists who brought agriculture from the Middle East. Did genetic adaptations of agriculturalists, such as the ability to digest milk as an adult, might have undergone genetic recombination with genetic adaptations of hunter-gatherers to potentially create a better adapted population in terms of survival and reproductive success? Why or why not?
