We here at LIME's "Planet" section are big dog lovers (meaning we have big love for all dogs, not that we love big dogs - I mean, we do love big dogs but also small ones), so we couldn't resist calling attention to a great story on the BBC's web site. It's about the history and evolution of dogs, as told through an exhibition called "Dogs: Man-Made Friends," on view at a branch of the UK's Natural HIstory Museum.
