Owls

I may have posted this before, but I still love the joke (obviously in the pictures, not in the text) on the Wikipedia entry for 'convergent evolution':

share keen, night-time binocular vision,
directional hearing (via mobile ears in
the cat and asymmetric ear openings in the
owl, and sharp claws for prey capture.
