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.

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

Accordingly, there was little need for a temporary trial period such as dating before a permanent community-recognized union was formed between a man and a woman.

While pair-bonds of varying forms were recognized by most societies as acceptable social arrangements, marriage was reserved for heterosexual pairings and had a transactional nature, where wives were in many cases a form of property being exchanged between father and husband, and who would have to serve the function of reproduction.

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.

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.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.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.Men and women became more equal politically, financially, and socially in many nations.In the twentieth century, dating was sometimes seen as a precursor to marriage but it could also be considered as an end-in-itself, that is, an informal social activity akin to friendship.
