Motivated in part by the inability of classic descent theory to describe sociality in Highland New Guinea, contributors to this model and their forerunners have emphasized that descent in Melanesia is either cognatic or--even where indigenously figured as unilineal--implies recursive relations of male/female complementarity (e.g. “Family Tree of Raúl Castro” By Basilio – Own work (CC BY-SA 3.0) via Commons Wikimedia.

In additional to cognatic descent (bilateral) the second major descent system is unilineal. There are two basic descent systems: corporate and cognatic. The patrilineal form is more common. In systems of double unilineal descent, society recognizes both the patrilineage and the matrilineage but assigns to each a different set of expectations. The difference between unilineal and cognatic clans is…. Evans, Tracy. A third method is to alter the history, myths, or folklore of a descent group in order to expand or contract its membership. “Family tree – male patrilineal descendants of Guðrøðr Óláfsson (d. 1187)” By Brianann MacAmhlaidh – Own work.

Her areas of interests include literature, language, linguistics and also food. “Kinship – Glossary.” Nature of Kinship, Palomar College, Available here.3. 1. v. t. e. Unilineality is a system of determining descent groups in which one belongs to one's father's or mother's line, whereby one's descent is traced either exclusively through male ancestors (patriline), or exclusively through female ancestors (matriline). Ego has chosen to join his father's ramage which brings him into a descent line which includes a set of descendants, shaded in blue, of his father's mother's mother, determined according to a series of personal choices. The practical importance of descent comes from its use as a means for one person to assert rights, duties, privileges, or status in relation to another person, who may be related to the first either because one is ancestor to the other or because the two acknowledge a common ancestor. Omissions? descent traced through male and female links.

Unilineal descent is a method of tracing kinship through only one gender, that is, tracing kinship through a single line of ancestors. The main difference between unilineal and cognatic descent is that unilineal descent traces kinship through only one parent’s ancestors, but cognatic descent traces kinship through both mother’s and father’s ancestors to some degree. Most modern societies use cognatic descent system, but traditional societies typical use unilineal descent systems. But, cognatic descent traces kinship through both mother’s and father’s ancestors to some degree. In cognatic descent, people trace kinship to other people through both males and females. This I would suggest, is a most significant feature of some bilateral societies, for while they lack the large-scale descent groups of unilineal societies, their cognatic networks are close and The term descent groups is thus limited to unilineal or double descent groups. I have suggested that the term be used in societies that recognize a unilineal core within a cognatic descent category to denote descent status through at least one alternate-sex link (i.e., non-agnatic where descent includes at least one female link, nonuterine where it includes at least one male link)." To ease the understanding, we tend to group practices on the basis of similarities- and this explains the dual categorization of descent groups as either unilineal or cognatic. Unilineal descent and cognatic descent are two types of tracing kinship. If two people share an ancestor in a nonunilineal descent system they are cognates of each other. While these groups cannot handle the large array of functions of unilineal groups, the few functions they do handle are nevertheless important ones. In contrast to nonunilineal descent, unilineal descent traces an individual’s descent through one sex only, either through the father (patrilineal) or mother (matrilineal). For example, the inheritance of immovable materials, such as land, may be the domain of the patrilineage, while the matrilineage controls the inheritance of moveable objects such as livestock. Interestingly, many cultures that notionally adhere to a given descent system have methods whereby the system can be abridged.

Thus, while descent through the male line was notionally preferred, in practice the descent system was often bilateral—traced through either or both parents.

Cognatic descent refers to a method of tracing kinship through both mother’s and father’s ancestors to some degree.
