Imagine that a scientist discovers a new, flying species of mammal that resembles a winged rabbit. what can the scientist say about this organism? if molecular sequence data show that bats and this new species share a common ancestor not shared by other mammals, the wings of these two species would be considered analogous. if molecular sequence data show that bats and this new species do not share a common ancestor not shared by other mammals, the wings of bats and this new species would be considered homologous. no data could support or disprove the hypothesis that the wings of bats and the new species are homologous. if molecular sequence data show that bats and this new species share a common ancestor not shared by other mammals, the wings of these two species would be considered homologous. without any further information, the scientist can say that bat wings and the wings of this new species are homologous.
