| All pairwise sequence alignments were colinear, that is, blocks were sequential in nucleotide position for each taxon and were nonoverlapping. |
| Such a radical change in the mitochondrial gene arrangement within a closely related taxon has never been observed in other coelomate phyla. |
| The first formal use of the word Testudines as a taxon name can be found in Batsch. |
| According to our results, Sclerothorax is nested well within the higher stereospondyls, forming the sister taxon of capitosauroids. |
| This group is represented by a single extant species which is thought to be the sister taxon to all other frogs. |
| As shown above, using a third taxon to estimate the initial pairwise distances improves their precision. |
