Chickens First\ud \ud Speciation by “Hopeful Monsters” in Fraternal Supertwins\ud [PDF]
, 2008 The idea of “hopeful monster” was proposed by Goldschmidt who envisioned that speciation could occur instantaneously via major chromosomal rearrangement in a one-step process; but he could not unravel how similar individual in the opposite sex to appear ...

Molecular mechanisms underlying nuchal hump formation in dolphin cichlid, Cyrtocara moorii
Scientific Reports, 2019 East African cichlid fishes represent a model to tackle adaptive changes and their connection to rapid speciation and ecological distinction. In comparison to bony craniofacial tissues, adaptive morphogenesis of soft tissues has been rarely addressed ...

Molecular Ecology, Volume 34, Issue 21, November 2025.ABSTRACT Hybridisation is a common feature of evolutionary radiations, but its genomic consequences vary depending on when it occurs. Since reproductive isolation takes time to accumulate, hybridisation can occur at multiple points during divergence. Previous studies suggested that the taxonomic diversity in evolutionary radiations can help infer the ...

FishesThe radiation of cichlid species in the East African Great Lakes is remarkable and rapid. The population genetics of two deep-water Cyphotilapia species along the east coast of Lake Tanganyika from Burundi to southern Tanzania was determined using ddRAD ...

Evolution Letters, 2018 Explaining why some lineages diversify while others do not and how are key objectives in evolutionary biology. Young radiations of closely related species derived from the same source population provide an excellent opportunity to disentangle the ...

Science, 2018 Showing their stripes The adaptive radiation of East African cichlids has led to more than 1200 species across a number of lakes. Across these species, many convergent traits have emerged, including the presence or absence of horizontal stripes ...

Genetic and developmental origins of a unique foraging adaptation in a Lake Malawi cichlid genus
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Biologists have long been captivated by novel traits because they provide insights into both the origin of and constraints on morphological variation. The iconic adaptive radiations of cichlid fishes have led to incredible diversity of form,
