DR P. Z. Myers has a wonderfully written thought piece out on Pharyngula
, uniting a few highlights of human paleoanthroplogy and chronological perspective, with a touch of scientific spirituality thrown in. Worth far more than the five minutes it takes to read. PZ is a contributing editor to The Panda's Thumb and a long time FAQ and feedback author on Talk Origins. He's an excellent resource for those of you who are interested in learning more about defeating pseudoscience and institutionalized mysticism.
