However, one particularity of the human species is that pair bonds are often formed without necessarily having the intention of reproduction.

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.

It generally happened in that portion of a person's life before the age of marriage, enabled dates to be arranged without face-to-face contact.

Still, dating varies considerably by nation, custom, religious upbringing, technology, and social class, and important exceptions with regards to individual freedoms remain as many countries today still practice arranged marriages, request dowries, and forbid same-sex pairings.

Although in many countries, movies, meals, and meeting in coffeehouses and other places is now popular, as are advice books suggesting various strategies for men and women, in other parts of the world, such as in South Asia and many parts of the Middle East, being alone in public as a couple with another person is not only frowned upon but can even lead to either person being socially ostracized.

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.

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.

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.
