Bears may be the most intelligent of the North American mammals according to their brain structure, the experience of animal trainers, and tests at the Psychology Department at the University of Tennessee. Grizzly bear mothers spend 1½ to 3½ years showing their cubs where and how to obtain food. The cubs’ ability to form mental maps and remember locations may exceed human ability.
