The idea that Behe’s flagellum motor has been answered is wishful thinking at best, and corrupt science at it’s worst (scientism: which is an insertion of a metaphysical principle stating things like “the only quantifiable reality known is the one made up of atoms, and, science [thus defined] is the best means to understanding said reality”). Really, then, it is an “evolution-of-the-gaps” type thinking.
But as one can see… these giants of I.D. did truly wipe the floor with their critics [full exchange].
By-the-way, all this just got WAY MORE complex. For instance, here is the fast-swimming magnetotactic bacterium MO-1… it has 7-flagellum motors… with counter gears:
Here is a basic animation:
One should see Malcolm Bowden’s presentation on YouTube of the bacterium MO-1 as well.
And NOW even more complex is the fact that quantum mechanics may play a role (unrelated to the DNA or RNA) that folds these proteins into the shape for pieces to the whole of the working part.
