Speciation through sensory drive in cichlid fish
This work identifies the ecological and molecular basis of divergent evolution in the cichlid visual system, demonstrates associated divergence in male colouration and female preferences, and shows subsequent differentiation at neutral loci, indicating reproductive isolation. Expand
Pegasoferae, an unexpected mammalian clade revealed by tracking ancient retroposon insertions.
The interordinal mammalian relationships presented here provide a cornerstone for future studies in the reconstruction of mammalian classifications, including extinct species, on evolution of large genomic sequences and structure, and in developmental analysis of morphological diversification.

The genomic substrate for adaptive radiation in African cichlid fish
It is concluded that a number of molecular mechanisms shaped East African cichlid genomes, and that amassing of standing variation during periods of relaxed purifying selection may have been important in facilitating subsequent evolutionary diversification. Expand
LINEs Mobilize SINEs in the Eel through a Shared 3′ Sequence
It is demonstrated that short repeats at the 3' end of UnaL2 are required for retrotransposition suggesting that UnAL2 retrotransposes in a manner reminiscent of the reverse transcriptase activity of telomerases. Expand

This review covers the basic aspects of SINE evolution that are especially relevant to their use as systematic characters and describes the practical methods of characterizing SINEs for cladogram construction. Expand
Phylogenetic relationships among cetartiodactyls based on insertions of short and long interpersed elements: hippopotamuses are the closest extant relatives of whales.
It is concluded that cetaceans evolved from an immediate artiodactyl, not mesonychian, ancestor, thereby shedding light on the origin of whales. Expand
Functional noncoding sequences derived from SINEs in the mammalian genome.
AmnSINE1 appears to be the best example of a transposable element of which a significant fraction of the copies have acquired genomic functionality and is characterized here in the coelacanth, dogfish shark, hagfish, and amphioxus genomes. Expand
Retroposon analysis of major cetacean lineages: The monophyly of toothed whales and the paraphyly of river dolphins
The combination of SINE and flanking sequence analysis suggests a topology and set of divergence times for odontocete relationships, offering alternative explanations for several long-standing problems in cetacean evolution. Expand
Development of the embryo, larva and early juvenile of Nile tilapia Oreochromis niloticus (Pisces: Cichlidae). Developmental staging system
32 stages for Nile tilapia O. niloticus are newly defined using a numbered staging system to elucidate sequential events of craniofacial development and facilitate comparative evolutionary developmental biology studies of haplochromine cichlids, which comprise the species flocks of Lakes Malawi and Victoria. Expand
Retroposon analysis and recent geological data suggest near-simultaneous divergence of the three superorders of mammals
It is proposed that near-simultaneous divisions of continents leading to isolated Africa, South America, and Laurasia caused nearly concomitant divergence of the ancient placental ancestor into 3 lineages, Afrotheria, Xenarthra, and Boreotheria, ≈120 Ma. Expand
