Captive breeding – The species must breed well in captivity.Elephant farmers, for example, would have to wait perhaps twelve years for their herd to reach adult size. Growth rate – The animal must grow fast enough to be economically feasible.Non-finicky omnivores make the best candidates. Diet – To be a candidate for domestication, a species must be easy to feed.In chapter 9, six groups of reasons for failed domestication of animals are defined: Therefore, all successfully domesticated species are not so because of a particular positive trait, but because of a lack of any number of possible negative traits. Diamond uses this principle to illustrate why so few wild animals have been successfully domesticated throughout history, as a deficiency in any one of a great number of factors can render a species undomesticable. The Anna Karenina principle was popularized by Jared Diamond in his 1997 book Guns, Germs and Steel. In statistics, the term Anna Karenina principle is used to describe significance tests: there are any number of ways in which a dataset may violate the null hypothesis and only one in which all the assumptions are satisfied. This concept has been generalized to apply to several fields of study. In other words: happy families share a common set of attributes which lead to happiness, while any of a variety of attributes can cause an unhappy family. The name of the principle derives from Leo Tolstoy's 1877 novel Anna Karenina, which begins:Īll happy families are alike each unhappy family is unhappy in its own way. Consequently, a successful endeavor (subject to this principle) is one for which every possible deficiency has been avoided. The Anna Karenina principle states that a deficiency in any one of a number of factors dooms an endeavor to failure.
