Phylogenetic relationships between seven species of the catfish species flock from Lake Malawi (genus Bathyclarias) and other Clariid catfish have been investigated using cytochrome b partial sequences. Here we demonstrate that this species flock originated from a widespread, generalist species, Clarias gariepinus, still occurring in the lake. Bathyclarias species and their ancestor C. gariepinus form a simple model that can be used to understand the mechanisms of adaptation and rapid speciation in African Great lakes.
