"There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."

To evolve... is part of life , the random mutations together with the survival of the fittest has created the world we live in now. In this work this is presented by the fact that none of the clogs are the same, none of the clogs are perfect. They all have been selected for their mistakes, for their mutation. The tree has all sorts of elements, fruits and one of them might evolve in the next generation of clogs. One of the mutations now seen as beeing imperfect will make this species survie in the troubled world ahead of us. :)
