According to official census returns from Roman Egypt (first to third centuries CE) preserved on papyrus, 23·5% of all documented marriages in the Arsinoites district in the Fayum (n=102) were between brothers and sisters. In the second century CE, the rates were 37% in the city of Arsinoe and 18·9% in the surrounding villages. Documented pedigrees suggest a minimum mean level of inbreeding equivalent to a coefficient of inbreeding of 0·0975 in second century CE Arsinoe. Undocumented sources of…

The Papal decision to cite the rather vague but apparently allembracing ban on consanguineous unions in Leviticus 18:6 is noteworthy, and multiple pathways of consanguinity, which often occur in small endogamous communities, were ignored in the latter revision.

Brother-Sister Marriage in Roman Egypt: a Curiosity of Humankind or a Widespread Family Strategy?

Kin Endogamy, marriage between siblings, has been a practice among several cultures of the world. This is a deviation from positions of sociologists, anthropologists and psychologists on a universal

Incest Laws and Absent Taboos in Roman Egypt

For at least two hundred and fifty years, many men in the Roman province of Egypt married their full sisters and raised families with them. During the same era, Roman law firmly banned close-kin

Consanguinity, Genetic Drift, and Genetic Diseases in Populations with Reduced Numbers of Founders

The present chapter first considers the concepts of random and assortative mating and then examines demographic, social, economic, and religious variables that influence the prevalence of preferred types of consanguineous marriage, as well as the effects of Consanguinity on human mate choice, reproductive success, and reproductive compensation.

Marriage, Property and Conversion among the Zoroastrians: From Late Sasanian to Islamic Iran

AbstractThis essay discusses the impact of xwēdōdah or consanguine marriages, sanctioned by the Zoroastrian tradition on the population during a time of religious dialogue, and proselytizing in

Consanguineous marriage and human evolution.

This work has indicated that the shift from consanguineous marriage to panmixia has been accompanied by a reduction in homozygosity, and predicted decrease in incidence of both recessive single-gene disorders and more common adult-onset diseases.

Annie Darwin's death, the evolution of tuberculosis and the need for systems epidemiology.

In 1870, Darwin motivated his mathematician son George to study the prevalence of close-kin marriages in patients in asylums in comparison with the prevalence in the general population, and concluded that ‘the evil [of marriages between cousins] has been often much exaggerated’ and that � ‘under favourable conditions of life, the apparent ill-effects were frequently almost nil’.

The Marriage Revolution in Late Antiquity: The Theodosian Code and Later Roman Marriage Law

Although much scholarly work has already been done on Roman marriage law, most of it deals with the classical era, and little has been done to explore the remarkably radical changes to marriage law



The effect of consanguineous marriages on reproductive wastage

No consistent increase in reproductive wastage was evident as the inbreeding coefficient, F, advances mainly because of decline in the wastage rate among the double first cousin marriages which represents only 2% of the sample.

Consanguinity and reproductive behaviour in a tribal population 'the Baiga' in Madhya Pradesh, India.

In consanguineous couples the reproductive period was longer than in unrelated couples, probably to allow compensation for increased reproductive losses (infant and childhood deaths) and allowance must be made for this in assessing the influence of consanguined marriage on fertility and mortality.

Of a total 885 marriages studied in the Mala population of the Chittoor district, 321 were consanguineous (36.37%), a figure higher than that reported previously by Sanghvi and Mukherjee (1966) and in agreement with the results of some studies reported earlier.

Relationship between birth order of spouses with different degrees of consanguineous relationship.

Given the distribution of age differences between the spouses and assuming a standard age-sex structure, it seems possible to estimate the optimum frequency with which at least close consanguineous marriages occur in any particular population.

Trends in human reproductive wastage in relation to long‐term practice of inbreeding

Taking into consideration the various socio-demographic factors, the narrowing differentials in the reproductive wastage between consanguineous and non-consanguineously marriages from the oldest to the youngest women confirm the tapering effects of continued inbreeding practices on the reproductive Wastage.
