We argue that comparing adult behavior and cognition across cultures is insufficient to capture the multifaceted complexity of cultural variation. We champion a multidisciplinary perspective that draws on biological and psychological theory and methods. We provide examples for ways in which cross-cultural, developmental, and comparative studies might be combined to unravel the interplay between universal species-typical behaviors and behavioral variation across groups and, at the same time, to explain uniquely human cultural diversity by identifying the unique and universal patterns of human behavior and cognition in early childhood that create, structure, and maintain variation across groups. Such a perspective adds depth to explanations of cultural variation and universality and firmly roots accounts of human culture in a broader, biological framework. We believe that, therefore, the field of cross-cultural psychology may benefit from combining efforts with comparative and developmental psychologists.
