### Different/contrasting approaches
- Behaviourism — Focuses on learned behaviors from environment and reinforcement, not inherited mental modules, so it explains actions via experience rather than evolved adaptations.
- Psychodynamic theory — Emphasizes unconscious drives and early relationships shaping behavior, contrasting EP’s focus on inherited functions shaped by selection.
- Cultural psychology — Argues behavior is shaped primarily by culture and social norms, challenging EP’s emphasis on biological universals.
- Developmental systems theory — Prioritizes complex interactions among genes, environment, and development over fixed evolutionary programs, opposing EP’s modular, adaptation-centric explanations.
### Adjacent concepts
- Evolutionary biology — Provides the genetic and selective principles EP borrows to explain psychology, offering the biological mechanisms behind behavioral traits.
- Behavioral ecology — Studies how behavior adapts to ecological conditions in real time, complementing EP by focusing on current cost–benefit trade-offs rather than ancestral adaptations.
- Life history theory — Examines how organisms allocate energy across growth, reproduction, and survival, helping explain psychological differences across ages and environments.
- Gene–culture coevolution — Explores how genes and culture influence each other over time, bridging purely biological EP claims and cultural explanations.
### Practical applications
- Clinical psychology (evolutionary-informed therapy) — Uses evolutionary ideas to reframe anxiety, depression, or social problems as mismatches between modern life and evolved expectations, differing from standard symptom-focused therapies.
- Organizational behavior — Applies evolved motives (status, cooperation, reciprocity) to improve teamwork and leadership, offering a biological perspective distinct from purely managerial theories.
- Public health and mating strategies — Designs interventions (e.g., sexual health, parenting programs) that account for evolved preferences and life-history trade-offs, contrasting with approaches based only on social norms.
