Believe

Change, 

In the world we live in,

Change is not as easy as it seems.

In evolution,

There is the term 'historical constraints,'

That explains how cats can not become chickens. 

We can adapt, based on pre-existing conditions in our bodies that are more favourable to the latest weather overhead,

But a cat, to summarize, will always retain the basic likeness and functions associated with cattiness.  

Perhaps we can break this form,

Perhaps humanity is the species that evolutionists did not predict. 

Perhaps we can break from the cultural, societal, and biological expectations, the habitual repititions, we maintain in our narrowed view of the world.

If there was one thing I would change, it would be our lack of belief.
