abstract = {We present the first genomic-scale analysis addressing the phylogenetic position of turtles, using over 1000 loci from representatives of all major reptile lineages including tuatara. Previously, studies of morphological traits posi- tioned turtles either at the base of the reptile tree or with lizards, snakes and tuatara (lepido- saurs), whereas molecular analyses typically allied turtles with crocodiles and birds (archo- saurs). A recent analysis of shared microRNA families found that turtles are more closely related to lepidosaurs. To test this hypothesis with data from many single-copy nuclear loci dis- persed throughout the genome, we used sequence capture, high-throughput sequencing and pub- lished genomes to obtain sequences from 1145 ultraconserved elements (UCEs) and their vari- able flanking DNA. The resulting phylogeny provides overwhelming support for the hypothesis that turtles evolved from a common ancestor of birds and crocodilians, rejecting the hypothesized relationship between turtles and lepidosaurs.}
