Dorsal Ventral Asymmetry

Dorsal Ventral Asymmetry is a term in biology that describes the up-down asymmetry in animal body plan. Gravity being what it is, there are lots of inevitable differences between up and down. Down is where the friction is, up is where the sunlight comes from, and things fall on you. Up is also associated with sublimation of our animalistic instincts and intellectual sphere, down with baseness, naturalness, physicality. We built around us civilized world, but we keep our volnurable bellies, unarmed with rational thought, close to the ground and nature.
