Evolution is a process of change. It occurs in any phenomenon where new or modified forms arise, and where there is competition for survival. Examples of such dynamic phenomena are language, political and economic systems, and of course, life itself.

Our species is a product of evolution. Due to the differences between humans and other animals, some people think that we are something else entirely, but understanding that we are animals is critical to understanding our motivations. The similarities between humans and our closest animal relatives are far greater than the differences.

Humans are not something outside of nature. We are just as much a part of nature as any other species.
