Under bilateral descent, every tribe member belongs to two clans: one through the father (a patriclan, called oruzo) and another through the mother (a matriclan, called eanda). Himba clans are led by the eldest male in the clan. Sons live with their father's clan, and when daughters marry, they go to live with the clan of their husband. However, inheritance of wealth does not follow the patriclan but is determined by the matriclan, that is, a son does not inherit his father's cattle but his maternal uncle's instead.⠀
Bilateral descent is found among only a few groups in West Africa, India, Australia, Melanesia and Polynesia, and anthropologists consider the system advantageous for groups that live in extreme environments because it allows individuals to rely on two sets of families dispersed over a wide area.⠀
