Caviomorpha

The term Hystricomorpha (from Greek ὕστριξ, hystrix 'porcupine' and Greek μορφή, morphē 'form')

Anomaluridae, and Pedetidae. Molecular and morphological results suggest the inclusion of the Anomaluridae and Pedetidae in Hystricomorpha may be suspect. Based on Carleton & Musser 2005, these two families are discussed here as representing a distinct suborder Anomaluromorpha
.

Classification

hystricomorphy
.

The modern definition of Hystricomorpha, also known as Entodacrya or Ctenohystrica, is a taxonomic hypothesis uniting the

paraphyletic
group.

The hystricomorph rodents, or at least members of Caviomorpha, are sometimes not regarded as rodents.[4] Most molecular and genetic research, however, confirms the monophyly of rodents.[5] Support for rodent polyphyly appears to be a product of long branch attraction.[6]

Hystricomorph rodents appeared in

primates,[8] which also appeared in South America in the Eocene when it was an isolated continent, long before the Great American Interchange
. All of this is still controversial, and new scientific discoveries on this subject are published regularly.
