Dating is a stage of romantic relationships in humans whereby two people meet socially with the aim of each assessing the other's suitability as a prospective partner in an intimate relationship or marriage.
It is a form of courtship, consisting of social activities done by the couple, either alone or with others.
New types of relationships formed; it was possible for people to live together without marrying and without children.
Information about human sexuality grew, and with it an acceptance of all types of sexual orientations is becoming more common.
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.
Today, the institution of dating continues to evolve at a rapid rate with new possibilities and choices opening up particularly through online dating.
Social rules regarding dating vary considerably according to variables such as country, social class, religion, age, sexual orientation and gender.
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.
