The Empire Strikes Back The Flagellum Unspun: The Collapse of "Irreducible Complexity" by: Kenneth R. Miller |
|||||||||||
-The flagellum has been put forward as the flagship model of an IC system that points to intelligent design. -Miller attempts to show that there were precursors to the system therefore not making it irreducibly complex. -he holds up a Type-III Secretatory system as a precursor to the flagellum -this device is used by certain cells to do cool thinks like spread the Bubonic plague -the TTSS system, as it's called, and the flagellum share about ten proteins with the flagellum having about 30 more unique ones -we can see a lot of similarity in the structures by looking at the pictures below |

-so evolution could have built on this earlier "irreducibly complex system" in order to get to the bacterial flagellum -Dembski has 2 responses to this: -1) the TTSS system has a different function from the flagellum and the former couldn't get to the latter with intelligent design -he says that a motorcycle engine can be used as a heater but it couldn't evolve into a motorcycle without intelligent design -the TTSS system represents only one step in a long series of processes that would have take place - can't walk from California to Japan just because you found the Hawaiian Islands -2) it is much more reasonable to say that TTSS evolved from the flagellum -water has been around for about 2 or 3 billion years making the flagellum a long needed invention -the TTSS systems is used on multi-celled organisms which means that is probably a much more recent invention |
