Kinship builds upon two complementary principles: descent and marriage. But both can be manipulated and fiddled with, by natives as well as by anthro… - Thomas Hylland Eriksen

Above all, there is no simple one-to-one relationship between culture and ethnic identity, despite what many still believe. There are ethnic groups with great internal cultural variation, and there are clear boundaries between ethnic groups whose mutual cultural differences are difficult to spot. Often, the variation within the group is greater on key indicators than the systematic differences between the groups.

The relationships between mother, father and children, family trees and genealogies, preferential treatment of relatives and alliances through marriage furnish us with some of the few really good and useful comparative concepts we have in anthropology. They exist everywhere in one form or another, and they differ in interesting ways. If the ultimate goal is to discover the unity of humanity through its manifold appearances, the profession cannot afford to let go of the still rich gold mine of kinship.

Many social scientists, including anthropologists, have been interested in the power inherent in gender relations, often described through the idiom of female oppression. It can be argued that men usually tend to exert more power over women than vice versa. In most societies, men generally hold the most important political and religious positions, and very often men control the formal economy. In some societies, it may even be prescribed for women to cover their body and face when they appear in the public sphere, and, paradoxically, these practices sometimes become more common as their societies become more modern. On the other hand, women are often capable of exerting considerable informal power, not least in the domestic sphere. Anthropologists cannot state unequivocally that women are oppressed before they have investigated all aspects of their society, including how the women (and men) themselves perceive their situation. One cannot dismiss the possibility that certain women in western Asia (the Middle East) see the ‘liberated’ western woman as more oppressed – by professional career pressure, demands to look good and other expectations – than themselves.
When studying societies undergoing change, which perhaps most anthropologists do today, it is important to look at the value conflicts and tensions between different interest groups that are particularly central. Often these conflicts are expressed through gender relations.
