Query: Amazing videos!

I use this series while teaching high-school biology to my son in home-school. The videos make the subject come alive in ways that no textbook can -- in fact, for many topics, I use the videos as primary source of information. The price may seem steep, but you're buying a very polished product with up-to-date information and current discoveries (as of around 2000).A word of warning to those who want to teach the topic from a creationist perspective: The evidence for evolution and adaptation that the videos present is so persuasive that if you watch these videos, you may struggle to maintain that perspective.
