Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
Molecular genetics is a sub-field in biology that investigates the structure, expression, and functions of genes, informing brain development and functions at the level of the genome. [54] In the context of personality neuroscience, methods in molecular genetics have been used to establish genetic underpinnings of personality traits. [55]
Bateman's paradigm thus views females as the limiting factor of parental investment, over which males will compete in order to copulate successfully. Although Bateman's principle served as a cornerstone for the study of sexual selection for many decades, it has recently been subject to criticism. Attempts to reproduce Bateman's experiments in ...
In evolutionary biology, parental investment is the expenditure of time and effort towards rearing offspring that benefits the offspring's evolutionary fitness at a cost to parents' ability to invest in other components of the species' fitness. Parental care requires resources from one or both parents that increases the fitness of their ...
The alternative five factor model of personality is based on the claim that the structure of human personality traits is best explained by five broad factors called impulsive sensation seeking (ImpSS), [note 1] neuroticism–anxiety (N-Anx), aggression–hostility (Agg-Host), sociability (Sy), and activity (Act).

Father and children reading. According to a literature review by Christopher Spera (2005), Darling and Steinberg (1993) suggest that it is important to better understand the differences between parenting styles and parenting practices: "Parenting practices are defined as specific behaviors that parents use to socialize their children", while parenting style is "the emotional climate in which ...
Flexibility is a personality trait that describes the extent to which a person can cope with changes in circumstances and think about problems and tasks in novel, creative ways. [1] This trait comes into play when stressors or unexpected events occur, requiring that a person change their stance, outlook, or commitment.
Inclusive fitness is a conceptual framework in evolutionary biology first defined by W. D. Hamilton in 1964. [1] It is primarily used to aid the understanding of how social traits are expected to evolve in structured populations. [2]
