  • Title: Retropositional events consolidate the branching order among New World monkey genera.
    Author: Osterholz M, Walter L, Roos C.
    Journal: Mol Phylogenet Evol; 2009 Mar; 50(3):507-13. PubMed ID: 19135536.
    Abstract:
    Due to contradicting relationships obtained from various morphological and genetic studies, phylogenetic relationships among New World monkey genera are highly disputed. In the present study, we analyzed the presence/absence pattern of 128 SINE integrations in all New World monkey genera. Among them, 70 were specific for only a single genus, whereas another 18 were present in all New World monkey genera. The 40 remaining insertions were informative to elucidate phylogenetic relationships among genera. Several of them confirmed the monophyly of the three families Cebidae, Atelidae and Pitheciidae as well as of the subfamily Callithrichinae. Further markers provided evidence for a sister grouping of Cebidae and Atelidae to the exclusion of Pitheciidae as well as for relationships among genera belonging to Callithrichinae and Atelidae. Although a close affiliation of Saimiri, Aotus and Cebus to Callithrichinae was shown, the relationships among the three genera remained unresolved due to three contradicting insertions.
