Milk kinship

Traditionally speaking, this practice predates the early modern period, though it became a widely used mechanism for developing alliances in many hierarchical societies during that time.

[2]: 315 One particular theory mentioned by Peter Parkes is an Arab folk-analogy that breast milk is supposed to be "transformed male semen" that arises from Héritier's Somatic Scheme.

Altorki indicated that milk kinship had received little attention from anthropologists, despite its recognised significance in Muslim family law as a complex impediment to marriage.

Milk kinship has since attracted further fieldwork throughout Islamic Asia and North Africa, demonstrating its importance as a culturally distinctive institution of adoptive affiliation.

[3] Héritier's somatic explanation has since been endorsed – and apparently confirmed – by several French ethnographers of the Maghreb, also being further developed in her monograph on incest.

Héritier explains Islamic juridical reckonings of milk kinship as the continuation of a somatic scheme of male filiative substances transmitted by lactation.

[3] But Parker critically interrogates its supposition of a peculiar Arab folk-physiology of lactation, whereby breast milk is supposed to be transformed male semen, yet mentions that Héritier has properly focused attention on evidently contested issues of 'patrifiliation' by breast-feeding, which remain to be understood.

[2] Parker posits that this somatic scheme seems to be unsubstantiated by current ethnographies, and also unwarranted in understanding the juridical reckoning of milk kinship that it purports to explain.

[2]: 310 Weisner-Hanks mentions the introduction in the fifteenth century of prohibitions in the Christian Canon Law, in which one is not allowed to marry any one suspected to be of respective kin.

[6] In the early modern period, milk kinship was widely practiced in many Arab countries for both religious and strategic purposes.

Like the Christian practice of godparenting, milk kinship established a second family that could take responsibility for a child whose biological parents came to harm.

"[2]: 308 The childhood of the Islamic prophet, Muhammad, illustrates the practice of traditional Arab milk kinship.
