Biological anthropologists are interested in both human variation and in the possibility of human universals (behaviors, ideas or concepts shared by virtually all human cultures). They use many different methods of study, but modern population genetics, participant observation and other techniques often take anthropologists "into the field," which means traveling to a community in its own setting, to do something called "fieldwork." On the biological or physical side, human measurements, genetic samples, nutritional data may be gathered and published as articles or monographs.

What would an idea shared by virtually all human cultures be considered?
Answer: human universals

In the Age of Reason philosophical tracts and speculations on history and human nature integrated literature with social and political developments. The inevitable reaction was the explosion of Romanticism in the later 18th century which reclaimed the imaginative and fantastical bias of old romances and folk-literature and asserted the primacy of individual experience and emotion. But as the 19th-century went on, European fiction evolved towards realism and naturalism, the meticulous documentation of real life and social trends. Much of the output of naturalism was implicitly polemical, and influenced social and political change, but 20th century fiction and drama moved back towards the subjective, emphasising unconscious motivations and social and environmental pressures on the individual. Writers such as Proust, Eliot, Joyce, Kafka and Pirandello exemplify the trend of documenting internal rather than external realities.

What literary movement in the 1700s recalled the fantastical literature of medieval times?
Answer: Romanticism
