Questions: Descent Systems: Unilineal and Cognatic

Question 1

In a matrilineal society, who is most likely to inherit a man's property and social position?

• A. His biological son
• B. His sister's son
• C. His mother's brother
• D. His wife's father

Answer: (B)

In a matrilineal system, group membership and inheritance trace through mothers. A man's own children belong to his wife's lineage, not his. His lineage successors are his sister's children — specifically her sons — who are the next male generation of his matrilineage. This strikes outsiders as counterintuitive because it contradicts the common assumption that biological fatherhood determines inheritance.

Question 2

Why do different societies have different descent systems (patrilineal, matrilineal, cognatic)?

• A. Patrilineal systems developed where fathers could be confident of biological paternity; matrilineal ones developed where they could not
• B. Descent rules are culturally constructed organizational solutions — different societies have developed different rules to manage rights, obligations, and group membership, not biological necessities
• C. Matrilineal systems are older, and patrilineal systems replaced them as societies modernized
• D. Descent systems are determined by economic mode — agricultural societies are patrilineal, foraging societies matrilineal

Answer: (B)

The 'paternity certainty' explanation (option A) is a common but discredited theory. Descent rules reflect cultural definitions of relatedness, not biological facts. All three systems are equally valid cultural solutions to the same problem: organizing rights, property, and obligations across generations. Different societies have arrived at different answers through historical, ecological, and social circumstances — not genetic knowledge.

Question 3

In a matrilineal descent system, women typically hold political authority over their lineage groups.

• T. True
• F. False

Answer: False

Matrilineal does not mean matriarchal. While group membership and inheritance trace through women, political authority in matrilineal societies often rests with men — specifically with a woman's brothers, who manage lineage affairs. The Akan of Ghana and the Khasi of northeast India are matrilineal, but authority over lineage property and decisions typically belongs to male kin. Confusing matrilineal with matriarchal is one of the most persistent errors in understanding kinship systems.

Question 4

Cognatic descent systems allow individuals to trace kinship affiliation through both the mother's and father's sides.

• T. True
• F. False

Answer: True

Unlike unilineal systems, which restrict descent to one line, cognatic (bilateral or ambilineal) systems permit tracing kin through both parents. This gives individuals overlapping kin networks rather than exclusive membership in a single bounded lineage. Western European and North American kinship is cognatic. Some ambilineal variants let a person affiliate primarily with one parent's group by pragmatic choice, such as land availability.

Question 5

Why does it matter whether a society uses patrilineal versus matrilineal descent? What practical aspects of social life does the descent rule determine?

Model answer: The descent rule determines who belongs to your corporate group — and therefore who you share property with, who you may or cannot marry (lineage exogamy rules), where you live after marriage, who fights alongside you, who you owe obligations to, and who inherits your position and property. It organizes the basic structure of political alliances, economic units, and household arrangements.

Descent rules are not just about family trees — they are the structural skeleton of social organization. Knowing a society's descent system lets you predict residential patterns, property transmission, marriage restrictions, political alliance formation, and the emotional valence of different kin relationships. This is why anthropologists treat descent systems as fundamental to understanding any society's organization — they are culturally constructed solutions with wide-ranging practical consequences.
