We propose that romantic love is a biosocial phenomenon that may well be a universal and that its cultural aspects are a product of social conditions. This position is unique because romantic love is promoted as a cultural rather than social universal. We argue that culture, social, and psychological phenomena are too frequently conflated and their core definitional features underdefined by researchers. Culture refers to learned practices that have collectively shared meanings to the members of a society. Under social conditions in which romantic love does not confer reproductive and health advantages to a mother and child, it will often be suppressed, undeveloped, and rejected as a cultural component. Through a cross-cultural study, we show that female status and family organization are important features that help in regulating the sociocultural importance of romantic love as a basis for marriage. The authors propose that romantic love is more likely to be a biosocial universal than a biocultural universal. We understand that there is a great deal of overlap between social and cultural, but we intend to make clear the distinctions, as we see them, between these two concepts. Richerson (1985, 2005) and Boehm (1999Boehm ( , 2012 have been proponents of a biocultural approach to the study of ''the origin and evolution of cultures.'' These researchers have developed a biocultural approach that remains true to the ethnographic cross-cultural approach of anthropology first advocated by Tylor (1889). Our work fits into this model for cross-cultural research, with the notable addition that the focus is on social conditions and practices from which cultural configurations emerge. In this study, we hope to accomplish the following tasks: First, we intend to demonstrate that the social aspect of romantic love has been neglected in cross-cultural research on love and is just as important as culture, if not more so, for the study of romantic love; second, we intend to show that female status and family organization are important features in regulating the sociocultural importance of romantic love, particularly (but not exclusively) as a basis for marriage; third, in our discussion, we present an argument for attending more carefully to definitions of core concepts (e.g., culture, romantic love) and the explanatory limits and strengths (or parameters) of those definitions; and fourth, we seek to stimulate interest in developing better (i.e., more reliable and valid) codings of the concept of romantic love (and other expressive/subjective concepts) in the cross-cultural databases. We began such studies over 15 years ago (de Munck &
