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.

These species-particular behavior patterns provide a context for aspects of human reproduction, including dating.

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

Historically, marriages in most societies were arranged by parents and older relatives with the goal not being love but legacy and "economic stability and political alliances", according to anthropologists.

The protocols and practices of dating, and the terms used to describe it, vary considerably from country to country and over time.

While the term has several meanings, the most frequent usage refers to two or more people exploring whether they are romantically and/or sexually compatible by participating in dates with the other.

With the use of modern technology, people can date via telephone or computer or meet in person.

This term may also refer to two or more people who have already decided they share romantic and/or sexual feelings toward each other.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.A few centuries ago, dating was sometimes described as a "courtship ritual where young women entertained gentleman callers, usually in the home, under the watchful eye of a chaperone," but increasingly, in many Western countries, it became a self-initiated activity with two young people going out as a couple in public together.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.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.
