To those who know of the fact, evidence for evolution of life on Earth is utterly overwhelming. But everyone has to learn it one fact at a time for themselves. Help that process along by posting your favorite bits of evidence here. And please include a link or source reference to support the evidence and allow us to dig into additional information about it.
