Platyrrhine Alu subfamilies Ta7, Ta10, and Ta15 were assigned names based on a standardized nomenclature. However, with the subsequent intensification of whole genome sequencing ... WebbAlu elements are primate-speciWc SINEs that make up a large portion of the human genome and are also widespread in other primates. Using a combination wet-bench and computational approach we recovered 190 Alu insertions, 183 of which are speciWc to the genomes of nine New World primates. We used these loci to investigate branching order …
WebbUnresolved issues remain, such as the relationships among the four major lineages of platyrrhine (New World) primates (Canavez et al., 1999; Singer et al., 2003) and among gibbon species (Mueller et al., 2003). However, the broad outline and much of the fine detail of primate evolutionary relationships is now known with substantial confidence.
