Survival of the fittest

A dove, A fly, A spider, A mammoth. These are all creatures. Some may be undesirable, And some may be long gone. Yet, at the end of the day, They are all creatures who have a purpose. Just because one does not understand it, Does not mean it isn't there. As can be said the same with anything. A beetle, A wolf, A human. These are all alive. They may not be for long, but they are alive. No matter how hard one must fight, If it wishes to, It will survive. That is the way things are. Nothing is understood, Yet it still stands.
