PRACTICE EXAM ANSWER KEY 1. In 2003 the journal Nature reported the following phylogeny for mammalian carnivores found on the large island of Madagascar (off the east coast of Africa). The geographic range is part of the common name of the species [Malagasy = from Madagascar]. Indian African African Malagasy Malagasy Malagasy lion civet mongoose mongoose civet fossa (a) Geological studies have shown that the island of Madagascar has most recently been connected to India, and it had been previously hypothesized that the Madagascar carnivores should therefore be most closely related to Indian carnivores. Does the phylogeny above support this hypothesis? Why or why not? No. The closest relatives to the Malagasy species are both African, not Indian. (b) Another hypothesis was that the extremely diverse Malagasy carnivore fauna had originated from three separate colonization events by African species. Specifically, it was hypothesized that the ancestors of Malagasy mongoose, civet and fossa had each independently dispersed across water from Africa to Madagascar. Does the phylogeny above support this hypothesis? Why or why not?
