Another option would be a process of cladogenetic speciation along the Early Pliocene, resulting in two different lineages of Debruijnimys, and unnamed species and D.
Wright & Stigall (2013a) divided cladogenetic events in these taxa into two temporal bins.
Phylogeographic approaches reinforce the hypothesis that the area of cladogenetic event was the central-western region of the country (La Rioja and Catamarca provinces) (Martinez et al., 2010b).
Dating of the cladogenetic events.--A likelihood ratio test (LRT) was used to test the molecular clock hypothesis, according to Huelsenback & Crandall (1997).
In recent years, many cladograms have been published for the species of families and genera of Neotropical animals usually with no discussions of the nature of the vicariance events which caused the numerous cladogenetic events underlying the speciation patterns depicted.
