Evolution bumper Sticker Contest

Greg Laden supplies the details.  Here are two of the rules:

• Be original. Run a Google search and make sure your slogan hasn't been used or overused.
• Size constraints. Your basic bumper sticker is about 2.75" high and about 15" wide. That's enough room for up to two lines of text, approximately 22 characters across (including spaces) per line. Remember: shorter is better.

The deadline is September 5.
