Replying to Everything We Do is Natural.

Is human development any different than other forms of development caused by other animals?

A 5 story parking garage isn't considered to be "nature" because it was built by humans, but an anthill is "natural" even though it was built by hoards of tiny ants with instinctual engineering degrees.

Some have told me that the human psyche is what differentiates us from other animals. But that brings up another question: is our current state of mind a natural occurrence? How is the progression of the foundation of our social, emotional, and logical selves any different than the evolution of another species?

Somebody please help me organize my brain goober.
