  1. DNA as in it’s unique fingerprint, But if you change a little bit the laws of nature, or you change a little bit the constants of nature—like the charge on the electron—then the way the universe develops is so changed, it is very likely that intelligent life would not have been able to develop.

  2. I recommend you read this – not being rude but there seems to be more to it. I didn’t understand everything the author claimed but there is plenty of evidence that there is some fine-tuned DNA-like evolution going on somewhere up there.

  3. I guess the parameters are the fixed constants of nature. But there lies the problem. The Anthropic Principle is an unfalsifiable statement (aka. a tautology) that results from the “selection effect” of our own existence. Meanwhile, the fine-tuning argument is a surprising fact about the laws of nature as we know them.
