Which statement is a tenet of the out of Africa hypothesis for the origin of modern humans? O O O O O Modern humans evolved in Africa and then migrated throughout the world, replacing earlier human populations. Modern humans evolved in Eurasia and migrated to Africa, driving resident populations of early humans out of Africa and resulting in their extinction. Homo erectus populations migrated out of Africa and interbred with Homo neanderthalensis populations in Eurasia to give rise to modern humans. Numerous Homo erectus populations that scattered throughout the world evolved simultaneously to give rise to modern humans.

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.
