Initially when we look at these charts it can be intimidating.  I mean, they "prove" evolution, right?  When I first started in this ministry these charts were what convinvced me that the Creationists were telling me the truth!  Sounds weird, I know.  Because of my background I was not a very trusting person.  I asked a LOT of questions.  I was asking both Christians and non-christians, creationists and evolutionists.  At the same time I was looking at the world around me to see what fit with what these folks were telling me.
