Ambilineality is a cognatic descent system in which individuals may be affiliated either to their father's or mother's group. This type of descent results in descent groups which are non-unilineal in the sense that descent passes either through women or men, contrary to unilineal descent, whether patrilineal or matrilineal.
An example of an Ambilineal lineage. In ambilineal lineage, descent is traced through either the maternal and/or the paternal lines, usually meaning that the individuals choose whether to affiliate with their mother or their father's group, or both. [14] [15] Ambilineal lineage can be bilineal or bilateral.
There are four main headings that anthropologists use to categorize rules of descent. They are bilateral, unilineal, ambilineal and double descent. [9] Bilateral descent or two-sided descent affiliates an individual more or less equally with relatives on his father's and mother's sides. A good example is the Yakurr of the Crossriver state of ...
Within the descent group patrilineal descent lines were hierarchically organized, with descent from elder brothers invariably ranking higher than descent from younger brothers. The oldest member of the senior line (da zong) was the group's leader and the sole person who could perform rituals honouring the group's deceased founder and chief ...
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). Both patrilineality and matrilineality are types of unilineal descent.
A lineage is a single line of descent or linear chain within the tree, while a clade is a (usually branched) monophyletic group, containing a single ancestor and all its descendants. [3] Phylogenetic trees are typically created from DNA, RNA or protein sequence data. Apart from this, morphological differences and similarities have been, and ...
Hawaiian kinship, also referred to as the generational system, is a kinship terminology system used to define family within languages.Identified by Lewis H. Morgan in his 1871 work Systems of Consanguinity and Affinity of the Human Family, the Hawaiian system is one of the six major kinship systems (Inuit, Hawaiian, Iroquois, Crow, Omaha, and Sudanese).
The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
