    • ‘Does the discovery of asymmetrical flight feathers on the forelimbs and hind limbs of dromaeosaurs affect the debate about the evolution of avian flight.’
    • ‘By mapping homologous skeletal elements of the vertebrate forelimb onto their phylogeny, an explicit alternative interpretation of the significance of Hox gene expression emerges.’
    • ‘The forelimbs are specialized to form flippers, and the hind limbs and pelvis are extremely small and do not normally extend out of the body wall of the animal.’
    • ‘They have no eyelids, and all species have four fingers on each forelimb, five toes on each hind limb, and caudal fins.’
    • ‘Additionally, a nonstandard lead was observed across the left forelimb and right hindlimb.’

    • ‘The several theories for the origin of avian feathers, as well as for the origin of the winged forelimb and avian flight, are all historical-narrative explanations.’
    • ‘Their stream-lined bodies entirely lack hindlimbs, their forelimbs are reduced, they have lidless eyes, and large external gills and gill slits.’
    • ‘The wings of birds, forelimbs of a lizard and human arms are homologies, because they are all derived from the same primitive structure in the common ancestor of these groups.’
    • ‘An obvious modification was the elongation of feathers or ‘proto-feathers,’ which extended and broadened the forelimb into a wing that was much more sensitive to air flow.’
    • ‘Both the forelimb and the hindlimb have one long bone that attaches to the body at one end and to two long bones at the other end.’
