The comb fingers are also among the porcupine relatives

The porcupine relatives (Hystricomorpha, partly also Ctenohystrica) are a subordination of the rodents (Rodentia).

General

The morphological criteria for this subordination are largely based on the structure of the lower jaw and the skull, especially the zygomatic bone . A further differentiation was made through molecular genetic studies, so that the thorntail squirrel relatives , which in the past were sometimes also included, are now classified as a separate suborder.

This subordination includes almost 300 species, most of which are common on the American continent .
