biophobia

n. a human fear of certain species (e.g., snakes, spiders) and general aversion to nature that creates an urge to affiliate with technology and other human artifacts, interests, and constructions rather than with animals, landscapes, and other elements of the natural world. Such fear is seen in many populations throughout the world, a pervasiveness that U.S. biologist Edward O. Wilson (1929–  ) and others consider indicative of its innateness. U.S. ecologist David W. Orr, however, emphasizes that biophobia is culturally acquired, a product of modern living that distances people from the natural world to such a degree that they become indifferent to other organisms and antagonistic toward the environment. Compare biophilia.

sexually dimorphic nucleus

sexually dimorphic nucleus

a nucleus of the central nervous system that differs in size between males and females. In humans, for example, a nucleus in the medial preoptic area of the hypothalamus that synthesizes gonadotropin-releasing hormone tends to be larger and more active in males than in females because gonadotropin release is continuous (it is cyclical in females). In songbirds whose males sing more than females, several brain nuclei associated with both song learning and song production are larger in males than in females.
