Detailed summary
A number of relevant articles address the evolutionary purpose of romantic love in humans and how it contributes to parental investment and long-term cooperation for offspring survival, with particularly significant references being [1, 3, 4, 5, 11].
The most relevant studies describe how romantic love evolved by co-opting mechanisms of mother-infant bonding [1], the fitness benefits and selective pressures of romantic love regarding pair-bonding [3], and the interdisciplinary support for romantic love as an evolved commitment device facilitating parental investment and social cooperation [4]. Positive associations between romantic love and reproductive success were also demonstrated in populations such as the Hadza hunter-gatherers [5]. Additionally, evidence supports the formation of monogamous relationships through romantic love, benefiting offspring survival and development by promoting long-term parental cooperation [11].
Categories of papers
The most important categories to highlight are those that explicitly address the evolutionary role of romantic love in humans, particularly regarding parental investment and long-term cooperation for offspring survival and development. Additional categories can include articles that discuss related aspects of romantic love's functions in humans, cross-cultural variations, and biological mechanisms, though not always with a comprehensive link to the desired focus.
Title 1: "Evolutionary Role of Romantic Love in Parental Investment" Description: Papers that explicitly focus on how romantic love has evolved to support parental investment and long-term cooperation for the benefit and survival of offspring. References: [1, 4, 5, 9, 11, 13]
Title 2: "Biological Basis and Neurological Mechanisms" Description: Papers discussing the neurobiological and endocrine systems, such as oxytocin and vasopressin, which underlie romantic love and attachment behaviors, partly linking them to parental investment. References: [1, 2, 28, 27, 35, 51]
Title 3: "Cross-Cultural Perspectives" Description: Papers that explore the impact and role of romantic love across different cultures, examining how these variations still contribute to a universal evolutionary function related to parental investment. References: [3, 6, 7, 8, 16]
Title 4: "Human Mating Strategies and Parental Investment" Description: Papers examining human mating behaviors and strategies, and how these influence or are influenced by the presence of romantic love, often linked to parental investment and offspring survival. References: [10, 17, 18, 20, 21, 22]
