Irreducible complexity is defined as “...a single system which is composed of several well-matched interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.”
Majikweo yasiyopunguzwa unafafanuliwa kama “….mfumo wa pekee ambao umetengezwa na sehemu nyingi ambazo zinaingiliana ambazo zachangia katika kufanya kazi, mahali ambapo ikiwa sehemu moja itatolewa inafanya mfumo wote kukosa kufanya kazi ipasavyo.”
