What gives the illusion of direction Copernicus, is the fact that you are looking at an organism, say a bird with a long tail, and with the gift of hindsight you see a direct line back through it's ancestors observing tails getting smaller back through time. Evolution doesn't take an attribute and develop it, it doesn't steer a species towards some imagined optimal goal, these are simply imaginings of the human mind. Evolution operates in the moment, selecting out whichever individuals fall prey to whatever pressures happen to be prevalent at the time. Evolution doesn't have a reverse, nor a forward momentum, it's merely the process of change. Non-goal orientated and non-directional.
