After reading the following, http://www.nytimes.com/2005/06/05/magazine/05FREAK.html?_r=1&oref=slogin, I'm a little more certain that there's no great designer in the sky. If a group of monkeys can figure out money with a little help, obviously evolution can push a species in that direction. Especially a species with an even more evolved brain.
To be honest, I suppose I'm a 99% athiestic-leaning agnostic. It's things like this that keep upping the percentage.
