    My theory is that it’s the possible terrestrial-equivalent to carcination ( the convergent-evolution of “crabs” evolving 6 separate times, in the sea, from different origins ).

    I’ve no idea if cladistics will back that,

    and don’t really care,

    but it seems that convergent-evolution would operate both in the air and in the water, so … possible … why not, eh?

      Yep, success is success, in any medium. convergent evolution can be found wherever we find life, from vents to the upper atmosphere. Terrestrial biology has had four and a half billion years to try everything, and try it in 50 different ages. Where characteristics impart a benefit to passing on genes, it’ll probably find success.

      I wonder after all those billions of years if we’ve had all the options tried, or if we’re just getting going. Probably depends on having a viable ecosystem tho. :|
