豪猪亚目学名:Hystricomorpha)在历史上曾有过许多含义。广义上是指所有具有豪猪型颧弓-咬肌结构(Zygomasseteric system)的啮齿目动物(跳鼠类除外),包括豪猪下目(Hystricognathi)、栉趾鼠科(Ctenodactylidae)、鳞尾松鼠科(Anomaluridae)、跳兔科(Pedetidae)。分子及形态学研究表明,将鳞尾松鼠科与跳兔科列入其中是有争议的。根据Carleton与Musser的研究[1],这两科被分为鳞尾松鼠亚目(Anomaluromorpha)。

豪猪亚目(又被称为Entodacrya或Ctenohystrica)的现代定义是指将栉趾鼠与豪猪下目联系起来的分类学假设。[1]支持这一说法有很多形态学以及分子系统发生学的证据。如果此假说是真实的,那传统观点中的松鼠形亚目将被推翻,成为一个并系群

豪猪类动物,或至少是豚鼠小目中的成员,有时会被认为是非啮齿类。[2][3][4]不过大多数分子与遗传学研究都表明啮齿动物是单系群[5][6][7][8][9][10]而支持啮齿类为多系群的证据被认为是源自长枝吸引(long branch attraction)的现象。[11]

豪猪类动物于渐新世早期出现于南美洲[12],这里此前的陆地哺乳动物只有后兽下纲贫齿总目南蹄目。豪猪类是从非洲横渡大西洋到达南美洲的。同一类型的迁徙还发生在灵长目中,这些都发生于南北美洲生物大迁徙之前。不过这些说法至今尚存争议。

分类 编辑

以下的分类是根据Marivaux等人对早期啮齿类化石进行的支序分类学分析而来的。[13][14]他们的研究支持豪猪亚目假说,并表明McKenna与Bell定义的先松鼠亚目(Sciuravida)[15]是多系群,因而并不成立。
