野生动物学报, 1987 研究大熊猫的免疫分类学性状,并讨论大熊猫在解剖学、遗传学和分子生物学方面的特征,认为大熊猫与熊类亲缘关系密切是无可辩驳的。主张大熊猫更为适宜的分类地位是并入熊科（Ursidae）,再立大熊猫亚科（A11uropodinae）。问题的提出关于大熊猫和小熊猫在分类学上的地位,一百多年来一直是生物学上一个难解之谜。虽然有不少学者,尤其是我国的学者把大熊猫划为独立的一科,把小熊猫划入浣熊科 （Procyonidae）,但是纵观发表的50篇论文表明,把大熊猫分为熊科（Ursidae）、浣熊科和自成大熊猫科 ...

Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.
