Final answer:
Two significant books in evolutionary psychology are "Personality and Individual Differences: A Natural Science Approach" by the Eysencks and "The Evolutionary Mismatch Hypothesis" by Li et al.,
which examine how traits and behaviors have evolved to enhance survival and reproduction.
Step-by-step explanation:
Two landmark books on evolutionary psychology include "Personality and Individual Differences: A Natural Science Approach" by H. J. Eysenck & M. W. Eysenck, and "The Evolutionary Mismatch Hypothesis: Implications for Psychological Science" by Li, van Vugt, and Colarelli.
Evolutionary psychology examines the biological causes of behavior and cognitive processes, hypothesizing that certain behaviors or traits have evolved to optimize reproductive success and survival in varying environments.
Developments in evolutionary psychology track back to Charles Darwin, who suggested that behaviors, much like anatomical features, adapt over time.
Contemporary evolutionary psychologists explore psychological phenomena that may serve as adaptations, which include personality development, cognitive patterns, and variations in behavior that could affect an individual's evolutionary success.
