Given how most of Madagascar's wildlife has developed in isolation for a long time, how does this species relate to this one:

As a layman question: was the long neck already developed and did the ancestor spread. Or, did multiple disparate species spontaneously evolve the same feature? Posted 6 years ago, modified 6 years ago

  My guess (!) would be that a long-necked ancestor must have been isolated when Madagascar split off (or maybe arrived later - some of these _do_ actually fly), but that is solely based on the fact that there are quite a few of these long necked species in the Attelabidae ... Posted 6 years ago

    Possibly some answers/theory in this one (to be found)?:

      Whoa, that is some obscure literature, sounds like a solid winter read! Seriously, thanks for your answer, I had no idea the feature was so common. Posted 6 years ago
