Confirmação da relação entre peixes-bois, "hyraxes" e elefantes, por meio do estudo da proteína das lentes dos olhos ()

Abstract: ResumoAs relações fi!ogenéticas entre os membros da super-ordem Paenungulata, os peixes-bois, elefantes e "hyraxes", foram Investigadas, utilizando-se a seqüên· ela de análises de aminoácidos da proteína oc A do cristalino da lente dos olhos destes animais . As aná· lises confirmam a origem monofilética das ordens Hyracoidea, Sirenla e Proboscidea e colocam os edentatas como os mais antigos do ramo da linha principal dos euterianos. seguidos pelos Paenungulatas como ra· mo mais próximo . Os resultados sugerem … Show more

“…The Sirenia is an ancient order of mammals with an extensive fossil record dating from the Eocene (Reinhart, 1959;Savage, 1976). It is a member of the Superorder Paenungulata and is most closely related to the elephants and hyraxes (De Jong & Zweers, 1980;Walker, 1964). The modem sirenians consist of two families: Dugongidae, which includes the dugong (Dugong dugon) and the extinct Steller's sea cow (Hydrodamalis gzgas); and Trichechidae, which is monogeneric with three species, the West Indian or Caribbean manatee (Trichechus manatus), the Senegal or West African manatee (T. senegalensis) and the Amazonian manatee (T. inunguis) (Bertram & Bertram, 1973).…”

“…Sirenians are generally slow‐moving animals with a low metabolic rate (Gallivan and Best, ), unlike cetaceans, which are normally highly active and fast‐moving, with mammaries located below the surface of the skin to help minimize water resistance during swimming (Pabst et al, ). Perhaps such streamlining is not so important for the sirenians, given that they are the only aquatic mammals with axillary mammaries; but more likely, the morphology and location of sirenian mammaries are pleisomorphic (De Jong and Zweers, ; Pabst et al, ), rather than an aquatic adaptation, as their closest living relatives, elephants, also have one pair of axillary mammaries (Miall and Greenwood, ; Laursen and Bekoff, ).…”

“…Os sirênios são filogeneticamente próximos aos elefantes, apresentando semelhanças moleculares e morfológicas (DE JONG;ZWEERS, 1980;KLEINSCHMIDT et al, 1986;CARTER et al, 2004;KELLOGG et al, 2007). Outra similaridade entre estas espécies é a presença dos múltiplos CLs durante o ciclo estral e gestação CHANNELLS, 1984;MARMONTEL, 1995;RODRIGUES et al, 2008).…”
