Here are Frans de Waal and David Berreby on bloggingheads.tv. If you are interested in the issues of science & religion, check out the discussion between 30-45 minutes. Frans has the appropriate tone to address not only the sensitive issue of the origins of morality, but also about science & religion, in general. He is empathetic (ha!) to believers but has a no-nonsense approach towards crazy claims, such as creationism, or that one cannot be moral without God. Good stuff.
I'm not completely sold on the bloggingheads format (sometimes the discussion can simply drag on), but I like this one, in particular the last half hour.
