Y-chromosomal Adam (Y-MRCA) is the patrilineal most recent common ancestor from whom all Y-DNA in living men is descended. An identification of a very rare and previously unknown Y-chromosome variant in 2012 led researchers to estimate that Y-chromosomal Adam lived 338,000 years ago (237,000 to 581,000 years ago with 95% confidence ), judging ...
In anthropology, a lineage is a unilineal descent group that traces its ancestry to a demonstrably shared ancestor, known as the apical ancestor. [1] [2] [3] Lineages are formed through relationships traced either exclusively through the maternal line (matrilineage), paternal line (patrilineage), or some combination of both (). [4]
[8] In 1962, Les Hiatt invalidated Radcliffe-Brown's theory of the horde, demonstrating that the empirical evidence from Aboriginal societies contradicted Radcliffe-Brown's proposal that hordes are always based on patrilineal descent. [9] The word "band" is also used in North America, for example among the indigenous peoples of the Great Basin.
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 ...
Where there are unilineal descent groups in a society (i.e. matrilineal and/or patrilineal), one's parallel cousins on one or both sides will belong to one's own descent group, while cross-cousins will not (assuming descent group exogamy).
The usual lack of matrinames to pass on in patrilineal cultures makes traditional genealogy more difficult in the maternal line than in the paternal line. [1] After all, father-line surnames originated partly to identify individuals clearly and were adopted partly for administrative reasons, [c] and these patrinames help in searching for facts and documentation from centuries ago.
Official surveys conducted during the early years of the Meiji era showed that the most common family form throughout the country during the Edo period was characterized by stem structure, patrilineal descent, patrivirilocal [clarification needed] residence and patrilineal primogeniture, but in some southwestern areas, that combination of ...
Sib is a technical term in the discipline of anthropology which originally denoted a kinship group among Anglo-Saxon and other Germanic peoples.In an extended sense, it then became the standard term for a variety of other kinds of lineal (matrilineal or patrilineal) or cognatic (i.e.,descended through links of both sexes) kinship groups.
