Not only has this perspective enabled the discovery of what appear to be strong universals in human mate choice but it has also facilitated our understanding of systematic variation in preferences both between and within…

Discussed are the division of labor, defenses, genetics and evolution, communication, and navigation power of honeybees. The scientific and cross-curricular themes that can be offered using the economically important honeybee are described. Research that suggests that bees may be flying magnets is also discussed. (KR)

Discusses topics to aid in understanding animal behavior, including the value of the biological approach to psychology, functional systems, optimality and fitness, universality of environmental effects on behavior, and evolution of social behavior. (DS)
