This Nova website, designed to accompany a television Feature Program on the world of Dogs, asks "How and why did man's best friend evolve from wolves, and why are dogs so remarkably diverse today?" The site showcases a slide show on working dogs and an interactive matching game entitled, Dogs Around the World. Also included at this website are a Teacher's Guide, a Links and Books page, and an Inquiry Article about Dog diversity. Additionally, this site links to the TV program transcript and to a recent "washingtonpost.com discussion with biologist and dog expert Ray Coppinger."
