When the human animal migrates, it’s not often instinctual. It is a daring foray into the unknown across lines, real and imagined. “It’s the journey, not the destination” is a sentiment that has inspired many a road trip and epic poem. But it’s not the journey, either. It’s the decision to take the journey, the impulse toward discovery. If there is one imperative we share with our finned and feathered friends, it is this: evolve or die. When we are free to move and adapt and change, we thrive.
