“Everything is simpler than you think and at the same time more complex than you imagine.”
(Johann Wolfgang von Goethe)
Complexity rises spontaneously in nature through processes such as self-organization. Emergent phenomena are common as are emergent traits, not reducible to basic components, interactions, or properties.
Complexity does not, therefore, imply the existence of a designer or a design. Complexity does not imply the existence of intelligence and sentient beings. On the contrary, complexity usually points towards a natural source and a random origin. Complexity and artificiality are often incompatible.
Artificial designs and objects are found only in unexpected (“unnatural”) contexts and environments. Natural objects are totally predictable and expected. Artificial creations are efficient and, therefore, simple and parsimonious. Natural objects and processes are not.
As Seth Shostak notes in his excellent essay, titled “SETI and Intelligent Design”, evolution experiments with numerous dead ends before it yields a single adapted biological entity. DNA is far from optimized: it contains inordinate...
