However, one particularity of the human species is that pair bonds are often formed without necessarily having the intention of reproduction.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 transgender couples, and that many heterosexual couples also bond for life without offspring, or that often pairs that do have offspring separate.With the use of modern technology, people can date via telephone or computer or meet in person.Dating may also involve two or more people who have already decided that they share romantic or sexual feelings toward each other.Dating is a stage of romantic relationships in humans whereby two people meet socially with the aim of each assessing the other's suitability as a prospective partner in an intimate relationship.It is a form of courtship, consisting of social activities done by the couple, either alone or with others.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.
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.
Today, the institution of dating continues to evolve at a rapid rate with new possibilities and choices opening up particularly through online dating.
