Teaching Ancient Nautilus New Tricks

\tWith its heavy outer shell, weak vision, and primitive brain, the nautilus lacks much of the excitement of the more flashy and cunning cephalopods. Yet a series of experiments by evolutionary biologists Dr. Jennifer Basil and Robyn Crook involving fish juice, blue lights, and mazes dispels the notion that this ancient species is incapable of basic learning and throws into question the origins of cephalopods' intellectual prowess.
