Abstract/OtherAbstract:
|
A 900- to 1100-bp fragment encompassing intron 1 of the nuclear transthyretin (prealbumin) gene was examined in 12 taxa of Old World hystricognath rodents of the families Bathyergidae, Petromuridae, Thryonomyidae, and Hystricidae. Within the Bathyergidae, Heterocephalus glaber (naked mole-rat) was basal, and the other East African species, Heliophobius argenteocinereus (silvery mole-rat), was sister to a southern African clade containing Bathyergus, Cryptomys, and Georychus (dune, common, and cape mole-rats). These results are congruent with studies using mitochondrial 12S rRNA gene sequences. A combined analysis of transthyretin and 12S rRNA data resulted in a well-supported topology with better resolution than either gene analyzed separately. These data support the findings by M. W. Allard and R. L. Honeycutt (1992, Mol. Biol. Evol. 9: 27-40) and R. L. Honeycutt (1992, Am. Sci. 80: 43-53) that complex social systems evolved independently at least twice, in the common and naked mole-rats. |
