Complex patterns can arise spontaneously from relatively simple physical and chemical interactions. Cells contain many examples of self-organization, including spatial patterns, oscillations, molecular assemblies, and dynamic structures.
If organized biological patterns can emerge from the properties of matter and interacting molecules, apparent organization does not necessarily require intelligent direction.
This objection is important because order by itself is not evidence of design. Nature produces many highly ordered structures without intelligent intervention.
Self-organization is a genuine and important feature of biological systems. Any design argument that treats all biological order as something natural processes cannot produce would be mistaken.
But self-organization does not answer every question about biological organization. We still need to distinguish spontaneous physical pattern formation from systems containing encoded information, regulated interactions, functional coordination, feedback, error correction, and inherited developmental programs.
The relevant question is therefore not whether matter can organize itself. It clearly can. The question is how far self-organizing processes explain the particular kinds of functional organization found in living systems.
Which features of living systems follow directly from self-organizing physical processes, and which depend upon additional inherited information and regulatory architecture?
