Great Plains. One man grabs a calf’s hind leg and lifts. Another seizes a front leg and heaves, flipping as easily as possible the two-hundred-pound animal. Then each man pulls hard to keep it still.

Nature, we learn, seeks to establish and maintain equilibrium. According to a study published late last year in Nature, Earth did just that, though not by design.
