Ancient hybridization fuels rapid cichlid fish adaptive radiations
Understanding why some evolutionary lineages generate exceptionally high species diversity is an important goal in evolutionary biology. Haplochromine cichlid fishes of Africa's Lake Victoria region encompass >700 diverse species that all evolved in the last 150,000 years. How this 'Lake Victoria Region Superflock' could evolve on such rapid timescales is an enduring question. Here, we demonstr...
متن کاملDeciphering ancient rapid radiations.
A deeper phylogenetic understanding of ancient patterns of diversification would contribute to solving many problems in evolutionary biology, yet many of these phylogenies remain poorly resolved. Ancient rapid radiations pose a major challenge for phylogenetic analysis for two main reasons. First, the pattern to be deciphered, the order of divergence among lineages, tends to be supported by sma...
متن کاملGeometric morphometric analyses provide evidence for the adaptive character of the Tanganyikan cichlid fish radiations.
The cichlids of East Africa are renowned as one of the most spectacular examples of adaptive radiation. They provide a unique opportunity to investigate the relationships between ecology, morphological diversity, and phylogeny in producing such remarkable diversity. Nevertheless, the parameters of the adaptive radiations of these fish have not been satisfactorily quantified yet. Lake Tanganyika...

متن کاملMolecular investigation of genetic assimilation during the rapid adaptive radiations of East African cichlid fishes.
Adaptive radiations are characterized by adaptive diversification intertwined with rapid speciation within a lineage resulting in many ecologically specialized, phenotypically diverse species. It has been proposed that adaptive radiations can originate from ancestral lineages with pronounced phenotypic plasticity in adaptive traits, facilitating ecologically driven phenotypic diversification th...
