Irreducible complexity is the argument that certain biological systems with multiple interacting parts would not function if one of the parts were removed, so supposedly could not have evolved by succ
Michael Behe believes that many aspects of life show evidence of design, using the mousetrap in an analogy disputed by others.
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
Irreducible complexity
…complex systems comes from Ludwig von Bertalanffy (1901–1972), an Austrian biologist. He believed that complex systems must be examined as complete, irreducible systems in order to fully understand how they work. He extended his work on biological complexity into a general theory of systems in a book titled…
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.
