I'm not sure I'm buying this one. (Just kidding. Who am I to say?)
Above is an artist's rendering of what The National Geographic and others say might be the missing link to the whale. About the size of a raccoon, scientists claim it shares many of the whale's physical and anatomical characteristics, including bone thickness, DNA, and something about the ears. It has long been theorized the whale evolved from a primarily land animal. Still, look at the thing. It looks more like an amphibious rat. I would rather believe the whale has more in common with a platypus (below). More on this story here.
