Free Essays on Sociobiology

Sociobiology, in its most recent form, dates from the 1970s and the work of Edward O. Wilson. However, the roots of sociobiology are older. The first use of the term sociobiology likely dates to the work of Warder C. Allee, Alfred E. Emerson, and their associates in their 1949 book, Principles of Animal Ecology. Sociobiogists study the behavior of social animals, including humans. Sociobiology developed from studies in population biology and genetics. Research in the social insects, especially ants and honey bees, had shown that the old Darwinian maxim of individual selection, of individuals working for their own reproductive success, did not seem to apply to those groups. The worker castes of those species donot reproduce; yet, their behavior in defense of their nests was tenacious and often life-threatening to the defenders. How could such behavior be explained? The answers began to crystallize when Hamilton (1964) developed the concept of inclusive fitness. Inclusive fitness incorporated not only one's own reproductive success, but also the reproductive success of relatives. In the social insects, all of the workers born of the same queen are full sisters, but, they are all even more closely related to their mother, the queen. So, if one transfers the logic of evolution from the individual to genes, then the behavior of social insects begins to make sense. When workers die in defense of their nests, they are more likely to increase the likelihood of their genes' survival, even though they died in the effort. Sociobiology, however, is far more than the study of social insects. It is the study of all social species. Further, it is an attempt to find the evolutionary pressures which led to the evolution of social behavior in diverse groups of animals. Sociobiology is most controversial when such analyses are directed at human behavior. For example, the question of human criminal behavior may be analyzed via sociobiology. I...
