Beauty Harmony and Evolution

Beauty is an emotional response that has a survival value from an evolutionary point of view. It is a response to harmony.

And what is harmony? It is a state in which many different elements carry a primary element in common. For example: All the plants in an area bend in the same direction, which is the direction of the dominant wind in that area.

All the colors in a landscape are influenced by the same strong light (orange sunset light for example), which gives them all a strong similar element.

In sounds: All the sounds are of the same pace, like crickets slowly chirping and plants softly whistling in the wind. It is a sign of a system in equilibrium.

And, as living things, we are attracted to systems in equilibrium because those tend to offer stable and foreseeable conditions for survival.
