Freaky Lab Animals
LiveScience has a gallery of some freaky lab animals like the mouse with three ears:
The mouse with a human ear growing on its back proved just how far science could, or would, go. The experiment saw a biodegradable, synthetic frame planted on the mouse; human cells were added to the frame and nourished by the mouse to produce, in effect, a real ear. With an ear-to-body ratio of about eighty percent, he's probably a very good listener.
