Abstract |
Many studies have been performed for the clarification of reptiles’ taxonomy. Some of
the basic unanswered so far questions are: what is the relationship between turtles, crocodiles
and squamata, which groups are monophyletic and what are the intra- and inter - orders and
suborders relationships of reptiles? Here, the phylogeny of 153 representatives out of 42
families of reptiles was examined by means of molecular markers (complete mitochondrial
genome, 37 genes and three nuclear genes, RAG-1, RAG-2, c-mos). Based on the produced
topology turtles belong to diapsid reptiles and Ophidia, Amphisbaenia, Anguimorpha and
Gekkota recognized as monophyletic groups. On the contrary, the monophyly of
Scincomorpha and Platynota is rejected. Moreover, it is supported the sister group
relationship between Amphisbaenia and Lacertidae, and Ophidia and Acrodonta. Within
Cryptodira the grouping of Chelydridae-Kinosternoidea is supported, whereas the monophyly
of Trionychoidea is rejected. Finally, in Amphisbaenia, the clade of
Amphisbaenidae/Trogonophiidae is more closely related to Blanidae. In total, the reptiles’
phylogeny presented here reveals the need of its systematic reevaluation and additional
investigation to fully resolve the relationships among reptiles.
