A molecular machine which has the ability to carry cargo on cellular highways has been a major buzz in some creationist and intelligent design blogs. This new discovery entails some very interesting facts.
Science daily reports…
“The researchers created high-resolution snapshots of a protein motor, called kinesin, as it walked along a microtubule, which are tube-shaped structures that form a cell’s “skeleton.” The result is the closest look yet at the structural changes kinesin proteins undergo as they ferry molecules within cells.”
“We see for the first time how kinesin’s atomic-scale moving parts allow it to pull itself and its cargo along a microtubule,” says Ken Downing, a biophysicist with Berkeley Lab’s Life Sciences Division. He conducted the research with postdoctoral fellow Charles Sindelar, now at Brandeis University.”
In PNAS Franck Fournio and Carolyn A. Moores make an interesting comment, “Thus the cell’s nanomachines have evolved to use ATP only when they can couple it to essential work.” Some say evolution has no objective, it’s mindless, but others say it’s goal is survival of the fittest so by allegedly creating the parts then fine tuning those parts for “essential work” would fit in their evolutionary framework.
However, life’s smallest motor shows, architecture, engineering, precision, and function which all fits the description of intelligence, namely God. The metaphysical explanation of evolution was just thrown in there because of what they believe, it really doesn’t contribute anything to the understanding of a protein that can shuttle cargo to various locations within the cell and assist with cell division.
Let’s put it this way, a mindless process cannot replace an intelligent engineer in the real world no matter how much time you give it, but in storytelling it can…Although in this case, the authors did not describe how this machine could have evolved but only assumed it did which is a “begging the question” answer.
