Here is an excellent talk by Eugenie Scott of the National Center for Science Education (NCSE). Some of the things in here are specific for the American context, but it still provides a nice overview of evolution. Perhaps, most importantly, it highlights the way debates within the scientific community often get misrepresented in the media. Check it out - it is about an hour long.
