Final Answer:
Additional support for biological influences on personality is established through research based in (d) Evolutionary theory.
Step-by-step explanation:
Evolutionary theory posits that certain personality traits and behaviors have evolved over time as adaptive mechanisms to enhance survival and reproduction. This perspective suggests that certain personality characteristics may have been advantageous for our ancestors, leading to their persistence in contemporary human populations. Research within evolutionary theory explores how specific traits may have provided survival advantages, shedding light on the biological foundation of personality.
In the context of personality psychology, evolutionary theory complements other perspectives like trait theory and provides a broader understanding of the roots of human behavior. Traits, as described in option (a), are observable patterns of behavior, and evolutionary theory can help explain why certain traits are prevalent in human populations. By emphasizing the role of natural selection, evolutionary theory contributes to the exploration of how personality characteristics may have evolved to enhance individuals' ability to adapt and thrive in their environments.
In conclusion, the recognition of biological influences on personality is further substantiated through research rooted in evolutionary theory. This perspective offers valuable insights into the adaptive functions of personality traits, enriching our understanding of the interplay between biology and personality development.
So correct option is (d) Evolutionary theory.
