title: The incest taboo and family structure.
abstract: The evolutionary advantage of outbreeding has influenced the family structure and the mating, attachment, and dominance behaviors of all animals. Nature has selected for those species that have evolved family structures with detachment and dominance patterns that create a relatively intact incest barrier. Man inherits from his animal forebears the biological imperative of an incest barrier but brings to it his special complexity of psychology and symbolization--incest barrier becomes incest taboo. We present a discussion of human patterns of speparation-individuation and Oedipal conflict and relate this to the detachment and dominance behaviors of animals. This is an interface between psychoanalysis, family theory, and ethology. In addition, we pursue in detail the asymmetrical operation of the incest taboo within the family: that it is stronger for mother-son than for father-daughter than for brother-sister.
