Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Boasting nearly 30,000 species, teleosts account for half of all extant vertebrates and
approximately 98% of all ray-finned fish species (Actinopterygii). Teleosts are also the …

Background Fish classifications, as those of most other taxonomic groups, are being
transformed drastically as new molecular phylogenies provide support for natural groups …

Background The duplication of genes can occur through various mechanisms and is thought
to make a major contribution to the evolutionary diversification of organisms. There is …

The origin of phenotypic diversity among higher clades is one of the most fundamental
topics in evolutionary biology. However, due to methodological challenges, few studies have …

Background The functional divergence of duplicate genes (ohnologues) retained from whole
genome duplication (WGD) is thought to promote evolutionary diversification. However …

Quantifying phenotypic evolutionary rates and their variation across phylogenetic trees is a
major issue in evolutionary biology. A number of phylogenetic comparative methods (PCM …

Whole-genome duplications (WGDs) have shaped the gene repertoire of many eukaryotic
lineages. The redundancy created by WGDs typically results in a phase of massive gene …

The current understanding of the origins of modern carbonate muds and their early stages of
transformations are reviewed. The fine-grained nature of such sediments makes them …

Teleost fishes comprise one-half of all vertebrate species and possess a duplicated
genome. This whole-genome duplication (WGD) occurred on the teleost stem lineage in an …
