The endemic cichlid fishes of Lakes Malawi, Tanganyika and Victoria are textbook examples
of explosive speciation and adaptive radiation, and their study promises to yield important …

Complex brains and behaviors have occurred repeatedly within vertebrate classes
throughout evolution. What adaptive pressures drive such changes? Both environmental …

Background The adaptive radiations of cichlid fishes in East Africa are well known for their
spectacular diversity and their astonishingly fast rates of speciation. About 80% of all 2,500 …

Lake Victoria harbors a unique species-rich flock of more than 500 endemic haplochromine
cichlid fishes. The origin, age, and mechanism of diversification of this extraordinary …

The mitochondrial cytochrome b (cyt-b) gene is widely used in systematic studies to resolve
divergences at many taxonomic levels. The present study focuses mainly on the utility of cyt …

▪ Abstract Cichlid fishes (Perciformes: Teleostei) found in the lakes of Africa have served as
model systems for the study of evolution. The enormous number of species (1000 in Lake …

Timing divergence events allow us to infer the conditions under which biodiversity has
evolved and gain important insights into the mechanisms driving evolution. Cichlid fishes …

About a dozen lakes in the world are up to three orders of magnitude older than most others.
Lakes Tanganyika (East Africa) and Baikal (Siberia) have probably existed in some form for …

Abstract With more than 3,000 species, the fish family Cichlidae is one of the most species-
rich families of vertebrates. Cichlids occur in southern and central America, Africa …

Lake Tanganyika, the oldest of the East African Great Lakes, harbors the ecologically,
morphologically, and behaviorally most complex of all assemblages of cichlid fishes …
