  Cytoskeletons are self organized networks based on polymerized proteins,
actin, tubulin, and driven by motor proteins, such as myosin, kinesin and
dynein. Their positive Darwinian evolution enables them to approach optimized
functionality self organized criticality. Dynein has three distinct titled
subunits, but how these units connect to function as a molecular motor is
mysterious. Dynein binds to tubulin through two coiled coil stalks and a stalk
head. The energy used to alter the head binding and propel cargo along tubulin
is supplied by ATP at a ring 1500 amino acids away.
