Document Summary
Romantic relationships defined: mutually exclusive, most species have mechanisms of avoidance for mating with other family members, sex and love are distinctly different in humans but not so much in animals. Underlying paradox: bad to breed with related individuals genetically, have certain mechanisms that create family/related avoidance. What are romantic relationships for: humans create an environment to raise their children and grow successfully, meeting the needs of the offspring fish don"t do this offspring never have a relationship with their parents. Polygamy (polygyny and polyandry): in mammals, polygyny is the most common most reproductive success in males. Promiscuity: both males and females are having sex with lots of different members of the opposite sex. Sexual selection: getting good genes from this male so that the sons will be seen as attractive and can obtain mates. Females often make the first move: females give a cue that they are reproductively ready.
