Caption: Photographs of Pleistocene wolf skulls from Rancho La Brea, California (above) and Alaska (middle). Bottom panel shows overlay of the outlines of the two skulls illustrating that although they are the same length, their shape is different-the wolf skull from Alaska is wider, and therefore those wolves had greater biting power.
