The raccoon school emphasizes on the similarity between giant panda and red panda, and the red panda has already been confirmed as member of raccoon family. Therefore, giant panda is just a large-size raccoon. Otherwise, from the morphologic anatomy, giant panda has a lot of similarity with red panda, both of the two species are rather fat, the structure of the cranium, the teeth and the front pals are similar, the face has black-white patterns, the four limbs are black, there are condyles over the tooth crown, and in the pal the additional sesamoids make up the grasping structure. Some primordial structural modes were seen within the skeletal and muscular systems. The carotid artery trunk has some similarity and the male pudendum is especially similar.
The 'independent family of giant panda' school consider that giant panda has different origin from that of bears or raccoons. It has unique characteristics in morphologic structure and other biological facets. Therefore, it shall be classified as the Giant Panda Family independently. The evolution of giant panda, according to studies of paleontologists Huang Wanbo et al, is approximately divided into the primal stage, the pullulating stage, the flourishing stage and the declining stage.
