Gears In Nature Disprove Neo-Darwinian Positions


NANOTECHNOLOGY

Gears, Motors, and “Cogs”


How does [chance] selection arrive at such coordination? What good is one gear without the corresponding gear? The challenge of IC [irreducible complexity] for Darwinism remains. ~ Uncommon Descent

Mind you, we have tiny motors (complete) found in nature that likewise fit Darwin’s own challenge of irreducible complexity — disproving neo-Darwinian positions… however, these gears provide yet another of many irreducible complexities that philosophical naturalism is hard-pressed to answer.

Atheist evangelist ~ Richard Dawkins ~ famous quip almost seems painfully funny:

  • “Biology is the study of complicated things that give the appearance of having been designed for a purpose.” (See more here)

Here is another evidence of “irreducibilities” found in nanotechnology, the Kinesin Motor:

One of the most amazing examples of cellular nanotechnology is a molecular motor protein known as kinesin. Kinesin is responsible for transporting molecular cargo — including chromosomes (e.g. during cell division), neurotransmitters and other important material — along microtubule tracks from one region of the cell to another. It is driven by ATP hydrolysis, thereby converting chemical energy into mechanical energy which it can use for movement. A kinesin molecule typically possesses two tails on one end, which attach to the cargo, in addition to two globular heads (often called “motor domains”) on the other end. Some readers may recognize this elegant protein from the now-famous Harvard animation, Inner Life of the Cell (time 1:59).

The sheer number of processes needed to be undertaken by such a motor protein makes the appearance of intelligent design seem almost beyond rational denial. Of course, many people resist this conclusion despite the evidence. As one Science Daily article in October 2010 put it,

“Our results show that a molecular motor must take on a large number of functions over and above simple transport, if it wants to operate successfully in a cell,” says Professor Matthias Rief from the Physics Department of the TU Muenchen. It must be possible to switch the motor on and off, and it must be able to accept a load needed at a specific location and hand it over at the destination. “It is impressive how nature manages to combine all of these functions in one molecule,” Rief says. “In this respect it is still far superior to all the efforts of modern nanotechnology and serves as a great example to us all.” [emphasis added]….

If you watch the short videos below, keep in mind that all this complexity at the cellular/protein level needs to be up and running optimally for life to have happened… at all.

And what one should keep in mind is the time-factor in all this “evolution” involved in event the simplest working protein… even long time (billions of years) is not enough time to get “the show on the road” ~ see Not Enough Evolutionary Time.
