Dating is a part of the human mating process whereby two people meet socially for companionship, beyond the level of friendship, or with the aim of each assessing the other’s suitability as a partner in an intimate relationship or marriage. It can be a form of courtship consisting of social activities done by the couple. While the term has several meanings, it usually refers to the act of meeting and engaging in some mutually agreed upon social activity in public, together, as a couple.

The protocols and practices of dating, and the terms used to describe it, vary considerably from country to country and over time. The most common idea is two people trying out a relationship and exploring whether they are compatible by going out together in public as a couple who may or may not yet be having sexual relations. This period of courtship is sometimes seen as a precursor to engagement or marriage.

Dating as an institution is a relatively recent phenomenon which has mainly emerged in the last few centuries. From the standpoint of anthropology and sociology, dating is linked with other institutions such as marriage and the family which have also been changing rapidly and which have been subject to many forces, including advances in technology and medicine. As humans have evolved from hunter-gatherers into civilized societies and more recently into modern societies, there have been substantial changes in the relationship between men and women, with perhaps one of a few remaining biological constants being that both adult women and men must have sexual intercourse for human procreation to happen.

Humans have been compared to other species in terms of sexual behavior. 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.[4] According to Sapolsky, humans are somewhat in the middle of this spectrum, in the sense that humans form pair bonds, but there is the possibility of cheating or changing partners. These species-particular behavior patterns provide a context for aspects of human reproduction, including dating. However, one particularity of the human species is that pair bonds are often formed without necessarily having the intention of reproduction. In modern times, emphasis on the institution of marriage, generally described as a male-female bond, has obscured pair bonds formed by same-sex and transsexual couples, and that many heterosexual couples also bond for life without offspring, or that often pairs that do have offspring separate. Thus, the concept of marriage is changing widely in many countries.
