Although evolutionary psychology has been successful in explaining some species-typical and sex-differentiated adaptations, a large question that has largely eluded the field is this: How can the field successfully explain personality and individual differences? This article highlights some promising theoretical directions for tackling this question. These include life-history theory, costly signaling theory, environmental variability in fitness optima, frequency-dependent selection, mutation…

Evolved individual differences: Advancing a condition-dependent model of personality
Abstract The field of personality psychology offers a wealth of robust empirical research and a successful descriptive taxonomy, but neither explains the origins of the structure of human personality
Evolutionary Perspectives of Personality
Evolutionary psychology is an important meta-theoretical paradigm for understanding universal and sex-differentiated adaptations. Despite this, it remains somewhat ignored within the mainstream study
Evolutionary personality psychology: Reconciling human nature and individual differences
Personality, from an evolutionary perspective, represents a meta-category of the output of a suite of species-typical, relatively domain-specific, evolved psychological mechanisms designed in
Evolutionary perspectives on human personality: comment on “personality from a cognitive-biological perspective” by Y. Neuman.
The ideas regarding (1) the evolutionary basis of personality and (2) human sperm competition are focused on.
Evolutionary perspectives on the mechanistic underpinnings of personality
Abstract Evolutionary theory is the organizing framework for the life sciences because of its unique value in deriving falsifiable predictions about the causal structure of organisms. This chapter
Evolutionary and differential psychology: conceptual conflicts and the path to integration
The present article identifies the conceptual and theoretical problems that have kept differential psychology isolated not only from evolutionary psychology, but from explanatory approaches in general.
Personality and evolutionary strategies: The relationships between HEXACO traits, mate value, life history strategy, and sociosexuality
Abstract Evolutionary approaches to understanding personality variation have proposed how general personality factors might be reframed in terms of adaptive tradeoffs, but many of these explanations
Evolutionary aspects of personality development
Personality and its development have a long evolutionary history, beginning with subtle differences in behavior selected for as a consequence of life history strategies and culminating with the
Current Perspectives in the Study of Personality Across Cultures.
A comprehensive conception of personality would incorporate dispositional traits, characteristic adaptations, and life narratives considered within evolutionary and cultural contexts (McAdams & Pals,
The Origins of Extraversion: Joint Effects of Facultative Calibration and Genetic Polymorphism
These novel findings initially support an integrative model wherein facultative calibration and specific genetic polymorphisms operate in concert to determine personality variation.


The evolutionary genetics of personality
Genetic influences on personality differences are ubiquitous, but their nature is not well understood. A theoretical framework might help, and can be provided by evolutionary genetics. We assess

The author argues that each of the Big Five dimensions of human personality can be seen as the result of a trade-off between different fitness costs and benefits, and that genetic diversity will be retained in the population.
Evolutionary Personality Psychology
THIS CHAPTER IS divided into four principal sections. The first reviews several major current evolutionary psychological theories of personality. The next two cover empirical evidence for these

It is concluded that animal studies provide unique opportunities to examine biological, genetic, and environmental bases of personality and to study personality change, personality-health links, and personality perception.
Evolution, the Five-Factor Model, and Levels of Personality
ABSTRACT This article interprets the five-factor model as subsuming variation in normative, species-typical systems with adaptive functions in the human environment of evolutionary adaptedness. It is
Adaptive Individual Differences
Individuals differ in innumerable ways, some adaptive, some maladaptive, and some neutral. Personality theories, we argue, can profit from distinguishing among these importantly different types of
Sexual strategies theory: an evolutionary perspective on human mating.
A contextual-evolutionary theory of human mating strategies is proposed, hypothesized to have evolved distinct psychological mechanisms that underlie short-term and long-term strategies between men and women.
Adaptive genetic variation and human evolutionary psychology.
A model is presented that shows how a combination of genetic polymorphism and phenotypic plasticity might be favored by natural selection in humans and other species.
Life-history trade-offs favour the evolution of animal personalities
This model simultaneously explains the coexistence of behavioural types, the consistency of behaviour through time and the structure of behavioural correlations across contexts, and explains the common finding that explorative behaviour and risk-related traits like boldness and aggressiveness are common characteristics of animal personalities.
The evolutionary genetics of personality: Does mutation load signal relationship load?
The importance of personality in mate selection, the importance of non-additive genetic variance for personality traits, the links between personality and reproductively relevant outcomes, and the low positive assortment coefficients for personality are consistent with, but do not definitively verify, the hypothesis that mutations degrade personality performance.
