In effect, protein engineers are using the power of random change plus intelligent design to see what if anything will improve function.
The contrast between the evolutionary sterility of Lenski’s unintelligent Darwinian evolution and the evolutionary potency of Arnold, Smith, and Winter’s intelligent evolution is striking.
Darwinist Jerry Coyne misunderstands design science. Intelligent design is two scientific inferences.
The design inference is obvious but often implicit, because explicit acknowledgement of design in biology carries with it substantial career risk.
Coming from the National Center for Science Education or the New York Times, this is typical.
