Or, could you direct me to a source that describes these things? Thanks in advance.

Read "The Beak of the Finch" by Jonathan Weiner, for starters.

Or read C.S. Lewis' "Mere Christianity", by the atheist turned Christian. I, like him, find it much harder to believe randomness led to our universe's complexities, as opposed to creation. But then, secular humanists worship the human mind, and especially their own intellect, above all.
