Kristofer m. helgen,6 mark s. springer,7 william j. murphy1* A full understanding of primate morphological and genomic evolution requires the identification of their closest living relative. In order to resolve the ancestral relationships among primates and their closest relatives, we searched multispecies genome alignments for phylogenetically informative rare genomic changes within the superordinal group euarchonta, which includes the orders primates, dermoptera (colugos), and scandentia (treeshrews). We also constructed phylogenetic trees from 14 kilobases of nuclear genes for representatives from most major primate lineages, both extant colugos, and multiple treeshrews, including the pentail treeshrew, ptilocercus lowii, the only living member of the family ptilocercidae. A relaxed molecular clock analysis including ptilocercus suggests that treeshrews arose approximately.
