I am a strong believer in darwanism. Natures way of trial by error. If something fails, it dies and doesn't reproduce; but if something works the creature survives and is able to reproduce. Compounded over millions (or billions) of generations and something is bound to happen (hence our existance). Sorry, creationism doesn't work for me.
For a good laugh and a practical application of darwinism check out
www.darwinawards.com. It's full of all the "creative" ways that people have removed themselves from the gene pool.
