“…Results also indicated frequent occurrences of homoplasy in morphological characters in the subfamily. These findings also support the necessity of molecular phylogenetic approaches to problems relevant to the origin of the New World lygosomine taxa, because their generic assignments have been made almost solely on morphological grounds (e.g., Greer, 1970aGreer, , 1979b; but see Mausfeld et al, 2000) In this study, we sequenced mitochondrial DNA for representatives of all three New World lygosomine genera, and analyzed resultant data together with corresponding data previously published (Honda et al, 2000) Australian Tiliqua , and one Scincus (belonging to the Scincinae) were also subjected to the sequencing procedure (Table 1, see Appendix for further details). Furthermore, we incorporated into the analyses data for other skinks representing the five major lineages of the subfamily Lygosominae, and the subfamily Scincinae published in our previous study (Honda et al, 1999b(Honda et al, ,c, 2000: Table 1).…”

“…Results of the analyses, while recognizing five distinct lineages within the subfamily (i.e., Sphenomorphus, Lygosoma, Egernia, Eugongylus and Mabuya groups), revealed non-monophyly for the genus Mabuya , as well as for the genus Sphenomorphus (Honda et al, 2000). Results also indicated frequent occurrences of homoplasy in morphological characters in the subfamily.…”

“…Previous studies revealed a relatively large degree of genetic divergences among lygosomine skinks (e.g., Honda et al, 2000;Mausfeld et al, 2000). Thus, we used 12S and 16S rRNA genes to avoid saturation of base substitutions because these domains seem to evolve more slowly than other mitochondrial genes (e.g., Keogh, 1998;Lee, 2000).…”

“…Thus, we used 12S and 16S rRNA genes to avoid saturation of base substitutions because these domains seem to evolve more slowly than other mitochondrial genes (e.g., Keogh, 1998;Lee, 2000). A part [approximately 1,250 base pairs (bp)] of mitochondrial 12S and 16S rRNA genes were amplified using the polymerase chain reaction (PCR) using primers: L1091 (5'-AAACTGGGATTAGATACCCCACTAT-3') and H1478 (5'-GAGGGTGACGGGCGGTGTGT-3') (Kocher et al, 1989) for 12S rRNA, and L2206 (5'-GGCCTAAAAG-CAGCCACCTGTAAAGACAGCGT-3'), L2606 (5'-CTGAC-CGTGCAAAGGTAGCGTAATCACT-3'), H3056 (5'-CTC-CGGTCTGAACTCAGATCACGTAGG-3') (Hedges et al, 1993) and H2741 (5'-AAGCTCCACAGGGTCTTCTCGT-CTTATG-3') (Honda et al, 2000) for 16S rRNA. The DNA sequences have been submitted to the DDBJ database, and their accession numbers are given in Table 1.…”

“…Alignments for DNA sequences were determined based on maximum nucleotide similarity using CLUSTAL X 1.8 (Thompson et al, 1994). In the previous study (Honda et al, 2000), we adjusted the output from CLUSTAL X with default gap penalties by eye considering the possible presence of secondary structures in the rRNA genes. However, secondary structures assumed as a result of this treatment were rather unstable because of the lack of comparable information for closely related taxa, and topologies of resultant trees were virtually identical between this procedure and those using the aligner.…”

Phylogenetic relationships of the three lygosomine skink genera occurring both in the Old World and the New World ( Mabuya, Scincella and Sphenomorphus ) were inferred from mitochondrial DNA sequence of 12S and 16S rRNA genes. Results strongly suggested the non-monophyly for any of these three genera. Within the Mabuya group, Asian members appear to have diverged first, leaving the Neotropical and the Afro-Malagasy Mabuya as sister groups. These relationships, together with the absence of extant or fossil representatives of the Mabuya group from North America, strongly suggest the trans-Atlantic dispersals of Mabuya from Africa to Neotropics. Our results also indicated a closer affinity of the New World Scincella with the New World Sphenomorphus than with the Old World Scincella . Such relationships suggest the trans-Beringian dispersal of the common ancestor from Asia and its subsequent divergence into the North American Scincella and the Neotropical Sphenomorphus .

Phylogenetic information offers an important resource in analyses of reproductive diversity, including interpretations of fetal membrane evolution. In this paper, we draw upon ongoing studies of South American and African lizards to consider the value of combining phylogenetic and reproductive evidence in the construction of evolutionary interpretations. South American lizards of the genus Mabuya exhibit several reproductive specializations that are convergent on those of eutherian mammals, including viviparity, long gestation periods, ovulation of tiny eggs, and placental supply of the nutrients for development. Studies of placental morphology and development indicate that New World Mabuya share several other derived features, including chorionic areolae and a "Type IV" epitheliochorial placenta with a villous, mesometrial placentome. Some characteristics of these lizards are shared by two African skinks, M. ivensii and Eumecia anchietae, including minuscule eggs, placentotrophy, an absorptive chorioallantois, and features of the yolk sac. Available evidence is consistent with two explanations: (1) placentotrophy originated in Africa, predating a trans-Atlantic colonization by Mabuya of the New World; and (2) placentotrophy arose two or three separate times among these closely related skinks. As illustrated by analysis of these animals, not only can data on fetal membrane morphology yield phylogenetic information, but phylogenetic evidence in turn provides a valuable way to reconstruct the evolution of fetal membranes in a biogeographic context. When appropriately interpreted, morphological and phylogenetic evidence can be combined to yield robust evolutionary conclusions that avoid the pitfalls of circular reasoning.

Partial DNA sequences from two mitochondrial (mt) and one nuclear gene (cytochrome b, 12S rRNA, and C-mos) were used to estimate the phylogenetic relationships among the six extant species of skinks endemic to the Cape Verde Archipelago. The species form a monophyletic unit, indicating a single colonization of the islands, probably from West Africa. Mabuya vaillanti and M. delalandii are sister taxa, as indicated by morphological characters. Mabuya fogoensis and M. stangeri are closely related, but the former is probably paraphyletic. Mabuya spinalis and M. salensis are also probably paraphyletic. Within species, samples from separate islands always form monophyletic groups. Some colonization events can be hypothesized, which are in line with the age of the islands. C-mos variation is concordant with the topology derived from mtDNA.
