The Cichlid Fishes of Lake Malawi, Africa

Abstract of Publication

Stiassny, M.L.J., and A. Meyer. 1999. Cichlids of the rift lakes. Scientific American 280 [February]: 64-69.  

[Brief abstract by M.K. Oliver:] These beautiful fish evolve at a dizzying pace. Hundreds of species live within just three African lakes, and many of them seem to have emerged almost overnight. But now human use of these environments threatens to exterminate these living laboratories for evolutionary studies. The authors assert (p. 69) "...that cichlids of Lakes Malawi and Victoria probably descended from a single lineage of mouth brooders (Haplochromini) that escaped from Lake Tanganyika." They diagram (1) the entire Lake Malawi flock(s) as being monophyletic, (2) the entire Lake Victoria flock as being monophyletic and the sister group of the Lake Malawi flock(s), and (3) Astatoreochromis alluaudi as the sister group of both flocks.
