How is exogamy adaptive

In nonindustrial societies, marriage can be a means to convert strangers into friends and of creating and maintaining personal and political alliances, relationships of affinity. Marriage is more of a group concern in nonindustrial societies; when an individual marries a spouse, they also assume obligations to a group of in-laws.

This is in great contrast to marriage in the United States, where marriage is more of an individual matter. In the US, marriage hinges on the idea that through marriage, a couple creates a new family and they are meant to leave their old families behind as they create a new home for themselves.

To an outsider, this would seem extremely strange: Why would the U. In addition, it is important to remember that the American ideal of marriage tends to be ethnocentric and neglects the diversity of marriage practices around the world. Another world appeared with the sexual management of information. Sexual reproduction actually combines two functions: multiplicative by "vertical transfer" and informative by "horizontal transfer".

This distinction is very common: polypus - medusa alternations, parasite multiplication cycles, the lytochal and deuterotochal parthenogenesis of aphids, and the innumerable para- and pseudo-sexual strategies of plants opportunistically combine the two modes of asexual replication and sexual combination. However, for the majority of animals and multicellular plants that produce many gametes, numerical proliferation by descendants and informative diversity by sexuality are mutually implicated, for example in the seed.

The true discovery of eukaryotes may not be the "true nucleus", as their name implies, but an orderly informative function. The field of recombinations circumscribes a class of partners genetically compatible with each other, each simultaneously prey and predator of the DNA of the other. The mythical Maxwell demon capable of tracing entropy by sorting molecules according to their state does exist: each mate is the other's Maxwell's demon. While a sexless bacterium is simply divided into two cells, two sexual parents work together to produce a single offspring a time.

Added to this are the burdens involved in meiosis and crossing-over, cellular diploidy, and mating. Sex produces an information gain that is paid for by a cost of energy-material, and this barter must be fair to survive. The domains of sexual intercourse are very diverse: uniparental reproduction, alternation of asexual proliferation and sexual information, self-fertilization, endogamy, exogamy, panmixis, diffuse or structured polymorphism, fertile or sterile hybridization, horizontal transfers.

Each species is a recombination field between two domains, cloning and hybridization. Multiplicative descent and informative fertilization are organically distinct, but selectively associated: the information produced by the parents' sexuality favors the predation of matter-energy and therefore the proliferation of offspring, and this proliferation in turn favors the sexed producers of information.

The equation specific to each species is: enough energy to proliferate, enough information to diversify. But these marginal modes have poor prospects, as the model of the species is successfully attractive.

Looking at it in a simple way, the inbreeding in each genetic combination "shuffles the cards of the gene deck" again, distributing a new combination but with the same elements.

Found insideMany books on kinship have been written by social anthropologists, but Primeval Kinship is the first book dedicated to the evolutionary origins of human kinship. In all societies the choice of partners is generally guided by rules of exogamy the obligation to marry outside a group ; some societies also have rules of endogamy the obligation to marry within a group. Exogamy forbade much more than marriage with mere kin. The more distant the mixture of the individuals, the descendants will be healthier and stronger.
