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.
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.
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.
Social rules regarding dating vary considerably according to variables such as country, social class, race, religion, age, sexual orientation and gender.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 people exploring whether they are romantically or sexually compatible by participating in dates with the other.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.These people will have dates on a regular basis, and they may or may not be having sexual relations.This period of courtship is sometimes seen as a precursor to engagement.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.Cars extended the range of dating as well as enabled back-seat sexual exploration.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.
