10 lessons:

1. 'Natural Human Tendencies': Evolved fears in infants show how we're designed for survival; not all inclinations are apparent at birth.

2. 'Mating Foundations': Early studies of couples tested evolutionary hypotheses, leading to a 37-culture study on mate preferences.

3. 'Innovative Framework': Teaching a course around evolutionary principles reshaped understanding of motivation from survival and mating perspectives.

4. 'Evolving Discipline': Friendship with like-minded theorists helped form evolutionary psychology, despite lacking precedent disciplines or widespread acceptance.

5. 'Consolidating Knowledge': The writing of the first textbook in evolutionary psychology synthesized broad topics like cooperation and status hierarchies.

6. 'Evolutionary Vision': Realizing the vast potential and foundational nature of evolutionary psychology to inform all social sciences and human behavior.

7. 'Groundbreaking Collaboration': Organizing a core focus group on evolutionary psychology foundations led to unique insights but challenges in collaborative book writing.

8. 'Universality and Adaptation': Empirical studies demonstrated the need for adaptations to be sensitive to environmental inputs like mate value feedback.

9. 'Psychological Mechanisms': Understanding how psychological adaptations like jealousy or parental investment are influenced by social and environmental contexts.

10. 'Psycho-Social Calibration': Research confirmed that many psychological adaptations require social feedback to be appropriately calibrated and implemented.
