The science of family — why human kinship is uniquely complex and what it reveals about us
1. The study of kinship, family systems, and social structures within human societies is a branch of which academic field?
- Sociology
- Social anthropology
- Demography
- Ethnography
Kinship was once considered the central concern of social anthropology — Claude Lévi-Strauss called it the 'atom' of social life. The field examines how cultures define family, who counts as kin, rules about marriage, and how kinship structures power and property. The diversity of human kinship systems is extraordinary.
2. In many cultures, a 'matrilineal' society traces descent through which line?
- The mother's line
- The elder's line
- Both lines equally
- The father's line
In matrilineal societies, property, titles, and group membership pass through the mother's line. A man's heirs are not his own children but his sister's children. The Minangkabau of West Sumatra (about 4 million people) are the world's largest matrilineal society. Matrilineal does not necessarily mean women hold political power.
3. The Trobriand Islanders, studied by Bronisław Malinowski in the early 20th century, had unusual beliefs about what aspect of reproduction?
- Death and reincarnation
- The gender of children
- Twin births
- The role of the father in conception
Malinowski reported that Trobriand Islanders denied that sexual intercourse caused pregnancy — believing children were spirits that entered the mother while she swam. The father's role was considered social, not biological. This view suited their matrilineal system perfectly and became one of anthropology's most famous case studies.
4. In many traditional cultures, an 'avunculate' relationship refers to the special bond between a child and which relative?
- Paternal aunt
- Eldest sibling
- Maternal grandfather
- Maternal uncle
In matrilineal societies, the maternal uncle (mother's brother) often serves the social role that the father serves in patrilineal cultures — providing discipline, property, and support. In ancient Rome, 'avunculus' (from which 'uncle' derives) specifically meant mother's brother, while 'patruus' meant father's brother — the language itself encoded their different social roles.
5. Which culture's kinship terminology, described by Lewis Henry Morgan in 1871, became foundational in anthropology for classifying family systems?
- Iroquois
- Cherokee
- Navajo
- Apache
Morgan found that the Iroquois system merged siblings with parallel cousins (father's brother's children and mother's sister's children) but distinguished cross-cousins (father's sister's and mother's brother's children). This 'Iroquois kinship' system is found across the world and reflects societies where cross-cousin marriage is preferred.
6. The universal incest taboo — prohibiting sexual relations between close relatives — extends in most cultures to which additional relatives?
- All of the above (varies by culture)
- In-laws
- All cousins
- Step-siblings
The nuclear family incest taboo (parent-child, sibling-sibling) is nearly universal, but extension to cousins, in-laws, and step-relatives varies dramatically. Some cultures require marriage between specific cousins (cross-cousin marriage). The taboo's evolutionary explanation is debated — the Westermarck effect (childhood co-residence reducing sexual attraction) is one leading theory.
7. What does the term 'fictive kinship' refer to in anthropology?
- Kinship in fictional narratives
- Kinship bonds assumed by adoption
- Ancient kinship myths
- Relationships treated like family bonds without biological connection
Fictive kinship includes godparents, 'play cousins,' close family friends called 'aunt' or 'uncle,' and gang membership described in family terms. Research shows fictive kin can provide the same social support benefits as biological family. The concept challenges the idea that 'real' family must be biological.
8. Which country has the highest average household size in the world?
- Pakistan
- India
- Mali
- Philippines
Mali has an average household size of around 8-9 people — one of the world's highest. Extended multi-generational households are the norm in much of West Africa, where polygynous families, grandparents, aunts, uncles, and cousins typically live together. By contrast, average household size in the EU is around 2.3 people.
9. What is 'cousin marriage' and how common is it globally?
- Marriage between step-cousins — rare, under 1% globally
- Marriage between second cousins — 20% globally
- Marriage between first cousins — around 10% of marriages globally
- Marriage between cousins of any kind — 30% globally
First cousin marriage is common across much of the Middle East, South Asia, and North Africa — in Pakistan, it accounts for over 60% of marriages. It's practiced to keep family alliances strong and property consolidated. In the UK and Australia it's legal; in the US, it's illegal in about half of states.
10. The term 'nuclear family' — referring to parents and children as a self-contained unit — became widely used after which historical period?
- The post-World War II era
- The Renaissance
- The Industrial Revolution
- The Great Depression
While nuclear families existed before, the post-war suburban boom in the US and UK created the ideal of the nuclear family as the social norm — parents, children, detached house, no grandparents present. This was historically atypical; for most of human history, multi-generational extended families were the norm. Many sociologists now see the nuclear family's dominance as a brief historical exception.
11. In evolutionary biology, 'kin selection' explains altruistic behaviour toward relatives. Which scientist developed this concept?
- W.D. Hamilton
- Charles Darwin
- E.O. Wilson
- Richard Dawkins
Hamilton formulated 'Hamilton's Rule' in 1964: altruism evolves when the benefit to a relative, adjusted by relatedness, exceeds the cost to the altruist. J.B.S. Haldane reportedly joked 'I would lay down my life for two brothers or eight cousins' — unknowingly anticipating Hamilton's math about shared genes.
12. Godparents play an important social role in many cultures. The institution of godparenthood (compadrazgo) is particularly strong in which cultural tradition?
- Southeast Asian Buddhist cultures
- East Asian Confucian cultures
- Northern European Protestant cultures
- Latin American Catholic cultures
In Latin American compadrazgo, the bonds between godparent and godchild (and between parents and godparents) create lasting social obligations — sharing resources, support, and loyalty. Anthropologists found it functions as a form of social insurance, extending reciprocal networks beyond biological kin. It can be more important than biological family in some communities.
13. Which British monarch's family adopted the surname 'Windsor' in 1917, replacing a German-sounding name?
- Queen Victoria
- George V
- Edward VII
- George VI
George V changed the Royal Family's name from Saxe-Coburg and Gotha to Windsor in July 1917 amid fierce anti-German sentiment during World War I. Kaiser Wilhelm II sarcastically said he couldn't wait to see the next performance of 'The Merry Wives of Saxe-Coburg-Gotha.' The name Windsor stuck and remains the Royal Family's official surname.
14. What percentage of people say their relationship with siblings is the longest-lasting relationship of their lives?
- Around 50%
- Around 80%
- Around 30%
- Around 95%
For most people with living siblings, the sibling relationship lasts longer than the relationship with parents (who die first) and often outlasts marriages. Research shows sibling relationships affect personality development, social skills, and lifelong wellbeing more than many parenting books acknowledge. Rivalry and closeness often coexist throughout life.
15. Which famous Victorian family, with Darwin marrying his first cousin Emma Wedgwood, showed what problem that Darwin himself worried about?
- The dangers of wealth concentration
- The social stigma of scientific careers
- The difficulty of maintaining scientific objectivity about family
- The effects of consanguineous marriage on health
Darwin studied plant inbreeding extensively and was so worried about the effects on his own children that he campaigned for the 1871 census to include questions about cousin marriage — a campaign that failed. Several of his children had health problems, and Darwin spent years wondering whether his marriage to Emma contributed to them.
