flagellum

Judge Jones might not realize it, but in a recent article in the York Dispatch he admitted that his ruling in the Kitzmiller v. Dover case amounted to judicial activism. He stated: “The decision seems to be holding up well … No other school district has engaged in this kind of a battle. I hope that’s a product of the decision and perhaps the way that I wrote the decision.” As Lawrence Baum writes in his book American Courts: Process and Policy, “[w]hen judges choose to increase their impact as policymakers, they can be said to engage in activism; choices to limit that impact can be labeled judicial restraint.” By admitting that he sought to impact the policy decisions of Read More ›

It’s been long known that the bacterial flagellum can spin in one direction and then quickly reverse directions and spin in the other. A recent issue of Nature has an article titled, “Structure of the torque ring of the flagellar motor and the molecular basis for rotational switching” which elucidates some of the biomechanical properties of the FliG motor protein that allows this rotation switch to occur: The flagellar motor drives the rotation of flagellar filaments at hundreds of revolutions per second, efficiently propelling bacteria through viscous media. The motor uses the potential energy from an electrochemical gradient of cations across the cytoplasmic membrane to generate torque. A rapid switch from anticlockwise to clockwise rotation determines whether a bacterium runs Read More ›

In 1998, Darwinian biologist David J. DeRosier stated in the journal Cell, “More so than other motors, the flagellum resembles a machine designed by a human.” Firstly, it functions like a human-designed rotary engine that propels a bacterium through a liquid medium in the same way a propeller powers submarine through the ocean. A website devoted to rotary engine enthusiasts has observed that when it comes to the Rotary engine, “Nature always does it first.” The flagellum is basically a rotary engine, with a motor, a rotor, a stator, a bearing, a u-joint, and a propeller. Now it turns out that the flagellum has a clutch. According to recent Research Highlights from Nature: “A protein that allows the soil bacterium Read More ›

To reiterate, there are three primary problems with Judge Jones’s ruling that Ken Miller refuted Michael Behe’s arguments that the bacterial flagellum is irreducible complex: Yesterday I posted sections addressing parts (A) and (B). Today I will continue with the response, expanding on Part (C): (C) Miller’s Incorrect Characterization of Irreducible Complexity To repeat Miller’s assertion, he testified that irreducible complexity is refuted if one sub-system can perform some other function in the cell: “Dr. Behe’s prediction is that the parts of any irreducibly complex system should have no useful function. Therefore, Read More ›

(Part I, Version 1.0) By Casey Luskin Copyright © 2006 Casey Luskin. All Rights Reserved. The entire article can be read here AbstractIn Kitzmiller v. Dover, Judge John E. Jones ruled harshly against the scientific validity of intelligent design. Judge Jones ruled that the irreducible complexity of the bacterial flagellum, as argued by intelligent design proponents during the trial, was refuted by the testimony of the plaintiffs’ expert biology witness, Dr. Kenneth Miller. Dr. Miller misconstrued design theorist Michael Behe’s definition of irreducible complexity by presenting and subsequently refuting only a straw-characterization of the argument. Accordingly, Miller claimed that irreducible complexity is refuted if a separate function can be found for any sub-system of an irreducibly complex system, outside of Read More ›
