As human beings, we have always endeavored to understand ourselves deeply: Who we are. How we should live. And how we are connected to the world around us—especially our culture and nature.

Our origins remain obscure. Perhaps, even a Mystery. Darwin revealed that species evolve. But told us nothing about the origin of life. Psychologists interpret who we are. But evolutionary psychology—which tells us why we are—remains controversial.

Yet our origins remain with us, and propel us onward.
