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.

Dating is a stage of romantic relationships in humans whereby two people meet socially, possibly as friends or with the aim of each assessing the other's suitability as a prospective partner in a more committed intimate relationship or marriage.

It can be a form of courtship that consists of social activities done by the couple.

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.

Thus, the concept of marriage is changing widely in many countries.

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 or marriage.

With the use of modern technology, people can date via telephone or computer or meet in person.

This term may also refer to two or more people who have already decided they share romantic or sexual feelings toward each other.

Cars extended the range of dating as well as enabled back-seat sexual exploration.
