Hasn't it been doing so for billions of years now?

  Only with strong selective pressure killing off the bad mutations (with is many/most of them). "But most human babies don't die. There are a bunch of mutations per generation, but not an exponentially compounded bunch of infant deaths, so how does our population get rid of bad mutations?" Because sperm are unit tests. The overwhelming majority of them die. You've got to regularly run the unit tests if you want to keep the codebase healthy :)
