When you encounter a snake… catch your breath, calm your heart, and watch it for a few seconds before it glides out of sight. If you do, you’ll see one of the most unexpected, and unnerving, spectacles in the animal kingdom. Limbless, a snake propels itself in waves, writhing and slithering along the ground. To climb, it will coil around a tree or pole, scrunching and creeping upward. To burrow, it relies on “rectilinear locomotion,” a unique coordination of scale and muscle movements that allow it to push its body forward in a straight line. Surprisingly, this uncanny way of getting around is the first specific animal phenomenon recorded in Scripture. And perhaps even more surprisingly, the snake is the first to receive the promise of Christmas.
