Line 7: Line 7:

The most commonly used examples of irreducibly complex biological systems are the human compound eye, the [[blood clotting cascade]], and the bacterial [[flagellum]].

Such examples have been showed to be flawed, for example precursors to the flagellum's motor can be found being used as ionic channels within [[bacteria]], known as the ''Type III Secretory System''.<ref>[http://www.millerandlevine.com/km/evol/design2/article.html The Flagellum Unspun]</ref> This is true for most of the structure of the flagellum in general; of the 42 proteins found in the flagellum, 40 have already been found in use in different biological pathways.<ref>[http://www.pandasthumb.org/archives/2006/12/ode_to_the_flag.html Ode to the Flagellum</ref> Even Behe's toy model used to illustrate the concept, the mouse trap, was countered by critics including biology professor John McDonald, who produced examples of how he considered the mousetrap to be "easy to reduce", eventually to a single part.<ref name=trap>[http://udel.edu/~mcdonald/mousetrap.html A reducibly complex mousetrap] (graphics-intensive, requires [[JavaScript]])</ref>
