paragraph_text: Bilateral descent
  
  Bilateral descent is a form of kinship system in which an individual's family membership derives from and is traced through both the paternal and maternal sides. The relatives on the mother's side and father's side are equally important for emotional ties or for transfer of property or wealth. It is a family arrangement where descent and inheritance are passed equally through both parents. Families who use this system trace descent through both parents simultaneously and recognize multiple ancestors, but unlike with cognatic descent it is not used to form descent groups.
  
  Traditionally, this is found among some groups in West Africa, India, Australia, Indonesia, Melanesia, Malaysia and Polynesia. Anthropologists believe that a tribal structure based on bilateral descent helps members live in extreme environments because it allows individuals to rely on two sets of families dispersed over a wide area.
