359. Evolution and Human Nature with Sam Wilkinson

What is the meaning of life? And what role does evolution play in our search for purpose? Join us in a conversation with Dr. Samuel Wilkinson, author of “Purpose: What Evolution and Human Nature Imply About the Meaning of Our Existence.” We cover some big, philosophical questions that don’t have clear answers but are so important to ponder. Our modern fears, our overactive stress responses, and the age-old struggle between good and evil—all these layers make up the complex human experience. Sam’s take on how our evolutionary history impacts our present-day lives is fascinating. So, wonderful listeners, tune in and reflect on these big ideas, and as always, we invite you to share your thoughts and takeaways.

  • How Sam’s personal struggle with the meaning of life intersected with scientific inquiry and ultimately led to him writing Purpose
  • Can you believe in evolution while maintaining religious or spiritual faith?
  • The importance of understanding genetics in the context of evolution
  • Exploring multi-level selection by redefining “survival of the fittest” across genes, individuals, kin, or groups, and discussing the implications for social traits and human nature
  • The tension between altruism and selfishness
  • How much of human aggression is rooted in biology versus culture?
