"The juvenile sea squirt wanders through the sea searching for a
suitable rock or hunk of coral to cling to and make its home for life. For
this task it has a rudimentary nervous system. When it finds its spot and
takes root, it doesn't need its brain any more so it eats it. It's rather
like getting tenure."
-- Daniel C. Dennett, Consciousness Explained, 1991
