| Abstract: | Background
Paedocypris, a highly developmentally truncated fish from peat swamp forests in Southeast Asia, comprises the world's smallest vertebrate.
Although clearly a cyprinid fish, a hypothesis about its phylogenetic position among the subfamilies of this largest teleost
family, with over 2400 species, does not exist. Here we present a phylogenetic analyses of 227 cypriniform taxa, including
213 cyprinids, based upon complete mitochondrial DNA cytochrome b nucleotide sequences in order to determine the phylogenetic position of Paedocypris and to study the evolution of miniaturization among cyprinids. |
