Platy-1 SINEs from Thirteen Diverse Genomes Reveal Callithrichidae Unique Amplification, Recent Alouatta Mobilization and Insights into Platyrrhine Phylogenetics

This study shows that callithrichids, and <i>Saguinus</i> tamarins in particular, are unique among platyrrhines with regard to their extensive rate of Platy-1 mobilization, a dynamic that appears to be correlated with LINE (L1) genomic content. <i>Alouatta</i> has two young lineage-specific Platy-1 subfamilies. With strong evidence of incomplete lineage sorting (ILS) and rapid radiation, the accurate placement of <i>Aotus</i> remains elusive.
