Human/Nonhuman Animals.

     Humans are able to form a historical record, learn from the past, and evolve their culture.  In humanity, culture compounds upon culture to benefit the race as a whole.  It is our technology and philosophy that defines us as a species.  We and we alone are gifted with the ability to solve complex problems and build on the past.

     In the animal kingdom, nature benefits species either through evolution or geological advantage.  Non-humans make no attempt to improve themselves or try to make their lives easier.  They do not learn from their ancestors so much as they outlive them.  There is no deeper meaning to their actions, no ideology that drives them.  There is loyalty at best and opportunism at worst.  The capability to autonomously improve is not present, and their value is directly tied to what they are capable of.
