Emergence

The formation of complex symmetrical and fractal patterns in snowflakes exemplifies emergence in a physical system.
A termite "cathedral" mound produced by a termite colony offers a classic example of emergence in nature.

In philosophy, systems theory, science, and art, emergence occurs when a complex entity has properties or behaviors that its components do not have on their own, and emerge only when they interact in a wider whole.

Emergence plays a central role in theories of integrative levels and of complex systems. For instance, the phenomenon of life as studied in biology is arguably an emergent property of chemistry and physics.
