"Molecular motors abound in the cell. Myosin motors power muscle contraction, kinesin motors move vesicles from one end of the cell to the other, and the ribosome processes along RNA."
"...all three types of rotary motor contain a central, ion-binding rotor ring that is embedded in the respective coupling membrane of the cell."

These molecular motors contain multiple structures and multiple processes integrated together and organized in such a way that the structures and processes not only support each other, they support the overall function of the motor.
These molecular motors cannot be explained by any combination of random, unguided, or accidental processes and have clear and inescapable purpose. And purpose requires intent. To assemble these molecular motors requires insight, and insight requires intelligence.
Their existence is prima facie evidence of intelligent input into living systems. If anyone believes that these systems can arise without intelligent input I would be interested in hearing alternative explanations.
