Below, read "errors" as "random processes".


Errors cannot produce high symmetry.

Errors cannot produce highly ordered information such as DNA.

Errors cannot produce interconnected systems with high codependencies, such as:

- rods/cones-eyelid-optical nerve-brain
- muscle-tendon-nerve-brain
- dual, symmetrical ear equilibrium systems
- ear-hair (detector)-converter (mechanical-to-electronic)-nerve (transmitter)-brain (processor)


An example of a brilliantly-designed sensory system which happens to have a mirror image device on the other side of the head:

The deflection of the hair-cell stereocilia opens mechanically gated ion channels that allow any small, positively charged ions (primarily potassium and calcium) to enter the cell. Unlike many other electrically active cells, the hair cell itself does not fire an action potential. Instead, the influx of positive ions from the endolymph in Scala media depolarizes the cell, resulting in a receptor potential. This receptor potential opens voltage gated calcium channels; calcium ions then enter the cell and trigger the release of neurotransmitters at the basal end of the cell. The neurotransmitters diffuse across the narrow space between the hair cell and a nerve terminal, where they then bind to receptors and thus trigger action potentials in the nerve. In this way, the mechanical sound signal is converted into an electrical nerve signal. The repolarization in the hair cell is done in a special manner. The perilymph in Scala tympani has a very low concentration of positive ions. The electrochemical gradient makes the positive ions flow through channels to the perilymph.
