Document Summary
Case study: adaptive radiation of fanged frogs. Case study: adaptive radiation, then mass extinction of cichlids in lake victoria. Example of a short answer question: please label each tip of this phylogeny using these words: monotremes , marsupials , and placentals so that they phylogeny accurately reflects their evolutionary relationships. Example of a short answer question: monotremes do not have nipples but placental and marsupials do. Please indicate with an arrow (or arrows) labeled nipples the portion of the phylogeny where you think they evolved. Please use the principle of maximum parsimony in your response. Essential by opening up opportunities in an environment that allows species to exploit and occupy ecological niches. Cichlids are a family or teleost fishes that include about 3000 species, about 10% of extant teleost diversity. Great lakes of tanganyika, malawi and victoria have around 250-800 species in each lake. Adaptations for feeding, variation in social behaviour, size and morphology.
