Acceleration of noncoding elements in viviparous species. A The location of syntenic introns and UTRs among 27 vertebrates with respect to the coordinates of the H. sapiens genome, with their associated genes annotated. B Trees for two convergently accelerated elements among viviparous species. The Bayes factors (BF1 and BF2; see Additional file 1: Supplementary Information), conservation rates (r1) and accelerated rates (r2) are indicated for each element
