One of the winners of the 2014 Kalvi Science Journalism Awards is the three-part PBS television series, Your Inner Fish. As far as I know the series not freely-available, but in it’s place you can watch this excellent presentation by Neil Shubin. If you’ve an hour of your time in the weekend, rather than watch some silly thing on TV you might try this excellent tale.
Neil Shubin is the Associate Dean of the Department of Biological Sciences, University of Chicago and also the author of a book, also titled Your Inner Fish.
