ExogamyExogamy is the custom of marrying outside a specified group of people to which one belongs. In addition to blood relatives, marriage to members of a specific totem or other group may be forbidden. The opposite of exogamy is endogamy. Different theories have been proposed to account for the origin of exogamy. Edvard Westermarck said it arose in the aversion to marriage between blood relatives or near kin, that is, in horror of incest. This is very probably the true solution. From a genetic point of view aversion to breeding with close relatives results in fewer congenital diseases because, where one gene is faulty there is a greater chance that the other - being from a different line - is of another functional type and can take over. Outbreeding thus favours the condition of Heterozygosity, that is having two copies of a given gene. McLennan please'' holds that exogamy was due originally to scarcity of women, which obliged men to seek wives from other groups, including marriage by capture, and this in time grew into a custom. Durkheim cite? derives exogamy from totemism, and says it arose from a religious respect for the blood of a totemic clan, for the clan totem is a god and is especially in the blood. Morgan and Howitt cite? maintain that exogamy was introduced to prevent marriage between blood relations, especially between brother and sister, which had been common in a previous state of promiscuity. Frazer says this is the true solution, that it really introduced group marriage, which is an advance to monogamy, and that the most complete record of this is the classificatory system of relationship. Lang, however, denies there is any group marriage, and says that so-called group marriage is only tribe-regulated licence. Hill-Tout cite? writes that exogamous rules arose for political reasons by marriage treaties between groups. Darwin denies primitive promiscuous intercourse, and says exogamy arose from the strongest male driving the other males out of the group. This is also the opinion of Lang, Atkinson, and Letourneau cite?. See chapter 18 of the Book of Leviticus for Biblical prohibitions on incest. See also
