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.
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.
These people will have dates on a regular basis, and they may or may not be having sexual relations.
