But genetic monogamy is strikingly very low in other species.

For instance, most wrasses are protogynous hermaphrodites in just a haremic mating technique.
Sexual relations involving people and animals have been essentially approached for a pathology within the fields of overall health science and biomedical science. These investigate has not taken into consideration the contextual and symbolic mother nature of so-termed zoophilia. Hardly any experiments have analysed zoophilia from the viewpoint on the social sciences. The taboo encompassing these procedures has silenced a actuality which is present in numerous societies. This paper examines the different ways wherein this phenomenon has long been tackled in disciplines which include anthropology, sociology and history, permitting us to know the different meanings and significances of zoophilia depending on the historic and cultural context.
