It is the largest recognized subspecies of brown bear, and one of the two largest bears alive today, the other being the polar bear. Physiologically, the Kodiak bear is very similar to the other brown bear subspecies, such as the mainland grizzly bear ("Ursus arctos horribilis") and the now-extinct California grizzly bear ("U. a. californicus"†), with the main difference being in size. While there is generally much variation in size

Yet its overall morphological characteristics suggest a kinship with the line of the speloid bears. Finally Garcia and Arsuaga have concluded that "Ursus dolinensis" "is the ancestor of "Ursus savini" and to be very close to the common ancestor of "Ursus arctos"". The type specimen of the Gran Dolina bear is a long left mandible fragment with the acronym "Ata96-TDW4-E9-1", that retains the canine, a premolar 4, a molar 2 and the alveoli of the premolars P1, P2 and P3.
