It’s a cold night and you bump into another similar organism just trying to stay warm and you both discover that where your cell walls touch is warmer.  So you stay touching through the night.  More cells join in each night to conserve energy and to stay warm and it becomes the best way to survive. So everybody does it.  The external environment and thermodynamics establishes an ethical strategy everybody shares to enhance life.
