Ridley's Law

Ridley's First Law

Science is the discovery of ignorance. It is not a catalog of facts.

Ridley's Second Law

Experience affects an organism largely by switching genes on and off. (Nurture works through nature.)

Ridley's Third Law

Neither the number of base pairs nor the number of genes in an organism's genome bears much if any relation to that organism's size or complexity.
