LAKE Victoria, together with its satellite lakes, harbours roughly 200 endemic forms of cichlid fishes that are classified as 'haplo-chromines'1,2 and yet the lake system is less than a million years old. This 'flock' has attracted attention because of the possibility that it evolved within the lake from one ancestral species3 and that biologists are thus presented with a case of explosive evolution. Within the past decade, however, morphology has increasingly emphasized the view that the flock… Expand
Origin of the Superflock of Cichlid Fishes from Lake Victoria, East Africa
TLDR
A haplotype analysis shows that the most recent desiccation of Lake Victoria did not lead to a complete extinction of its endemic cichlid fauna and that the major lineage diversification took place about 100,000 years ago. Expand
Response to Comment on "Origin of the Superflock of Cichlid Fishes from Lake Victoria, East Africa"
TLDR
A haplotype analysis shows that the most recent desiccation of Lake Victoria did not lead to a complete extinction of its endemic cichlid fauna and that the major lineage diversification took place about 100,000 years ago. Expand
Evolution of Labeo victorianus predates the Pleistocene desiccation of Lake Victoria: evidence from mitochondrial DNA sequence variation
Geological data show that Lake Victoria dried out some 15 000 years ago. These data suggest that the entire faunal diversity within the lake has evolved since this time. However, mitochondrial DNAExpand
Phylogenetic investigations on the haplochromine Cichlidae of Lake Kivu (East Africa), based on lepidological characters*
The phylogeny of the haplochromine cichlids of Lake Kivu was studied using lepidological characters. Only one species, Haplochromis astatodon was found to have a closer relationship to a groupExpand
Repeated colonization and hybridization in Lake Malawi cichlids
TLDR
Broad taxonomic sampling and nuclear DNA markers are used and find that the Lake Malawi radiation is not monophyletic, but instead contains genetic material from divergent riverine ancestors indicating multiple invasions and hybridization. Expand
Evolution in fast forward: haplochromine fishes of the Lake Victoria region
TLDR
The dynamics that underlie this fauna's extraordinary volatility are examined, and hence points the way towards its conservation. Expand
Why Are There So Many Cichlid Species? On the Interplay of Speciation and Adaptive Radiation
TLDR
Even with lower estimates of species number and higher estimates of the age of the species flock, the haplochromine cichlids still present one of the most dramatic examples of speciation and diversification in vertebrates. Expand
Genetic divergence, speciation and morphological stasis in a lineage of African cichlid fishes
TLDR
A case of surprisingly large genetic divergence among populations of the endemic Tropheus lineage of Lake Tanganyika, a lineage of six species that contains twice as much genetic variation as the entire morphologically highly diverse cichlid assemblage of Lake Malawi and six times more variation than the Lake Victoria species flock. Expand
Genetic population structure indicates sympatric speciation of Lake Malawi pelagic cichlids
TLDR
Mitochondrial DNA sequence data from 90 species, representing all major clades within the Lake Malawi flock, indicate reciprocal monophyly of the pelagic clade, suggesting that speciation in sympatry is more plausible (and widespread) within the cichlid species flocks than previously thought. Expand
Lake Tanganyika as an evolutionary reservoir of old lineages of East African cichlid fishes: Inferences from allozyme data
TLDR
Phylogenetic analysis based on the allozyme data indicated that at least seven old, ancestral lineages have contributed to the present cichlid fauna of the lake. Expand

TLDR
It is shown that trophic radiation in the Cuatro Cienegas cichlids has been achieved through ecological polymorphism rather than speciation, which raises questions regarding the genetic basis for the extensive intralacustrine radiation of cICHlids in Africa and elsewhere. Expand

TLDR
There are many other examples of introductions or invasions of non-native fish that have had severe effects on the native fish populations and regional economics and these examples should provide a clear warning against the proposed introductions of exotic fish into Lake Malawi. Expand

TLDR
The polymerase chain reaction is used to amplify homologous segments of mtDNA from more than 100 animal species, including mammals, birds, amphibians, fishes, and some invertebrates, and the unexpectedly wide taxonomic utility of these primers offers opportunities for phylogenetic and population research.

Mitochondrial DNA sequences in single hairs from a southern African population.
TLDR
Evidence of geographic structuring of the mitochondrial diversity in Africa, together with knowledge of the rate of accumulation of base changes in human mtDNA, implies that the average rate at which female lineages have moved their home bases during hunter-gatherer times could be as low as 13 meters per year.

TLDR
It is argued that the revised geological history of Lake Victoria provides a simple explanation of the main features of the lake ichthyofauna and is also consistent with the known biological changes. Expand
Sequence and organization of the human mitochondrial genome
TLDR
The complete sequence of the 16,569-base pair human mitochondrial genome is presented and shows extreme economy in that the genes have none or only a few noncoding bases between them, and in many cases the termination codons are not coded in the DNA but are created post-transcriptionally by polyadenylation of the mRNAs.
