Margaret Mead was an influential 20th century anthropologist who studied how culture and environment shape human behavior and development. Her most famous work, Coming of Age in Samoa, analyzed the transition to adulthood in Samoan society and found that Samoan adolescents experienced less stress and conflict compared to American youth. However, Mead's work has also faced criticism for potentially misrepresenting Samoan culture. Overall, Mead was an early proponent of the view that gender roles and social norms are culturally determined rather than biologically fixed.
