See this UCMP website, "Understanding Evolution" - a website about evolution for teachers.
Useful for anyone teaching any aspect of biology since it can all realte back to this on way or another. And its a pretty complex issue.
Thanks to Mark Salata (courtesy of OCKS), a guest of MOE, whom I met today. Who says in his webpage, "Hey, my education didn't just start in college - thanks to all of my teachers!"
