Fig. 2From: HERV-W group evolutionary history in non-human primates: characterization of ERV-W orthologs in Catarrhini and related ERV groups in PlatyrrhiniInitial formation of 211 HERV-W loci based on respective orthologs in Catarrhini primate reference genomes. The number of orthologs to HERV-W loci initially formed in a particular primate species is given for each species for proviruses, L1-retrotransposed processed pseudogene and undefined elements (see text for more details). For instance, 20 HERV-W loci were initially formed in the common ancestor of human and Gibbon, and 8 HERV-W processed pseudogenes were formed in the common ancestor of human and Orangutan. Note that the majority of HERV-W loci was initially formed in the common ancestor of human and Rhesus and is thus common to all Catarrhini genomes. Approximate time periods of last common ancestors of Catarrhini primate lineages are given in millions of years ago (MYa) below species namesBack to article page
