something that would really help: An up-to-date complete treatise of all the basic evidence that demonstrates the foundations of evolutionary theory.
Wrong tactic. A landslide of technical evidence will only bore and confuse your audience. What's needed is something simple. Like this:
Show them the bones. Teach kids a little anantomy. Give them casts of bones to examine. Show them how every mammal on earth shares certain features like hip bones and phalanges, even where they make no sense. Then show them primates, the grasping hands and similar skulls. Next show them how apes are different from monkeys and every other mammal - the rotating shoulder, supraorbital closure, lack of a tail, etc. Now show them human anatomy - how we share the basic simian body plan but our hips are wider and feet more rigid for upright walking. Show them the transitional forms: Australopithecus, H. ramidus, H. habilis, etc. At this point you barely need to say anything. The conclusion will smack them in the face like a cold wet fish.
It worked wonders for me. I went into my physical anthropology class a denier and came out a firm believer.
