The theory of evolution has wide-ranging implications on personality psychology. Personality viewed through the lens of evolutionary biology places a great deal of emphasis on specific traits that are most likely to aid in survival and reproduction, such as conscientiousness, sociability, emotional stability, and dominance.

Dual inheritance theory (DIT), developed in the late 1970s and early 1980s, has a slightly different perspective by trying to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. DIT is seen by some as a "middle-ground" between views that emphasize human ...
While EDP theory generally aligns with that of mainstream EP, it is distinguished by a conscious effort to reconcile theories of both evolution and development. [5] EDP theory diverges from mainstream evolutionary psychology in both the degree of importance placed on the environment in influencing behavior, and in how evolution has shaped the ...
The evolutionary theory of personality development is primarily based on the evolutionary process of natural selection. [13] From the evolutionary perspective, evolution resulted in variations of the human mind. Natural selection refined these variations based on their beneficence to humans.
Evolutionary psychologists consider Charles Darwin's theory of natural selection to be important to an understanding of psychology. [1] Natural selection occurs because individual organisms who are genetically better suited to the current environment leave more descendants, and their genes spread through the population, thus explaining why organisms fit their environments so closely.

The personality scales are associated with personality patterns identified in Millon's evolutionary theory and the DSM-5 personality disorders. There are two main categories of personality scales: Clinical Personality Pattern Scales and Severe Personality Pathology Scales.
But then, further, evolutionary theory suggests that sex differences in personality traits may enhance reproductive success for each sex. Cross-cultural studies have, however, found that women tend to be higher than men on both neuroticism and agreeableness, even though selection for a unitary general factor would mean that high agreeableness ...
Eysenck's three-factor model of personality was a causal theory of personality based on activation of reticular formation and limbic system. The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory.
