Behavior patterns are generally unwritten and constantly changing.

Historically, marriages in most societies were arranged by parents and older relatives with the goal not being love but legacy and "economic stability and political alliances", according to anthropologists.These people will have dates on a regular basis, and they may or may not be having sexual relations.This period of courtship is sometimes seen as a precursor to engagement.Neurobiologist Robert Sapolsky constructed a reproductive spectrum with opposite poles being tournament species, in which males compete fiercely for reproductive privileges with females, and pair bond arrangements, in which a male and female will bond for life.These species-particular behavior patterns provide a context for aspects of human reproduction, including dating.
