ResumoA new time-calibrated phylogeny shows that African and South American cichlids diverged long after the breakup of the two continents, suggesting that cichlid fi shes dispersed across the Atlantic around 82 million years ago, despite their predominantly freshwater lifestyle.The image shows the two landmasses after continental breakup in combination with the phylogeny of African (right) and South American (left) cichlid lineages.Photos of African and South American cichlid fi shes illustrate examples of the morphological variation exhibited by the two groups.South American species on the left-hand side are Andinoacara biseriatus, Amatitlania nanolutea, 'Geophagus' steindachneri, Andinoacara rivulatus and Caquetaia kraussii (top to bottom).To the right are the African taxa Pungu maclareni, Tilapia sparrmanii, Lobochilotes labiatus, Cyathopharynx furcifer and Serranochromis macrocephalus (top to bottom).All photos by Zuzana Musilová.Image design by
