- Abstract
The article discusses a study which examined leptin genes from gene sequence databases and used a series of maximum-likelihood methods to construct a phylogenetic tree for the gene in teleosts. Topics include the evolutionary patterns of leptin genes of mammals and teleost fishes, comparison of energy needs of teleosts and endotherms, and the branch-site models on ancestors of mammals and teleosts. It cites the role poikilothermia in teleosts to remain leptin genes under purifying selection.
