Malevolent Design (or M.D.) is one of the leading theories in micro-miracology, the division of Creation Science which deals with the origin and development of microorganisms, including bacteria, viruses and fungal parasites. Beginning with the fundamental insight of Creation Science that the complexity of life is such that it must be the result of divine intervention, and employing the micro-miracological observation that pathogenic organisms change rapidly in order to defeat or circumvent the human immune system, the theory of Malevolent Design posits that the adaptation of human pathogens is the result of malevolent actions taken by an intelligent designer. In layman's terms, the theory explains that humans continue to become sick because God hates us.
