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.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.Men and women became more equal politically, financially, and socially in many nations.Women eventually won the right to vote in many countries and own property and receive equal treatment by the law, and these changes had profound impacts on the relationships between men and women. In many societies, individuals could decide—on their own—whether they should marry, whom they should marry, and when they should marry.Generally, during much of recorded history of humans in civilization, and into the Middle Ages in Europe, weddings were seen as business arrangements between families, while romance was something that happened outside of marriage discreetly, such as covert meetings.From about 1700 a worldwide movement perhaps described as the "empowerment of the individual" took hold, leading towards greater emancipation of women and equality of individuals.
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.
The protocols and practices of dating, and the terms used to describe it, vary considerably from country to country and over time.
In the mid-twentieth century, the advent of birth control as well as safer procedures for abortion changed the equation considerably, and there was less pressure to marry as a means for satisfying sexual urges.
New types of relationships formed; it was possible for people to live together without marrying and without children.
