Parent–offspring conflict

Parent-child conflict is a by Robert Trivers 1974 embossed evolution theoretical model, from which a conflict between parents and offspring to the amount of parental effort results. The parents effort is defined as any behavior that the fitness of an offspring increases and reduces the cost of other young parents. The parents seek to maximize the number of surviving offspring. The single descendant also tries to maximize the number of his own offspring. If the descendants of passive recipients of parental effort are not, but to actively seek this, a conflict between parents and offspring can result. In particular, conflicts occur on about how much, and how long parents invest in a junior. The model predicts that offspring use various manipulations to obtain more resources from parents (but also that parents have developed defensive mechanisms against).
