As humans societies have evolved from hunter-gatherers into civilized societies, there have been substantial changes in relations 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.
Behavior patterns are generally unwritten and constantly changing.
There are considerable differences between social and personal values.

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.
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.
