From Uncommon Descent.
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.
