    Wings are an awesome development. But is it worth giving up arms and hands to get them?

    Evolution giveth, evolution taketh away.

    The vividly purplish-red feet are contrasted by the earthy-coloured plumage. Nice catch.

    I’d guess doves have to take a good care of their wings as they work them so hard.

    We’d need huge wings to fly, something like a 10 -- 12 m wingspan at least, judging by the estimated weights and wingspans of pterosaurs, hang gliders and modern birds. Going by the pterosaur model, we’d have 5-meter long pinkies.

    Ice swimmer, in theory, we could do with just a bit smaller than that, but certainly in that ball park. That’s about the size of a typical hang glider. If we had hollow bones, and the cardio and musculature to do some minimal flapping to get airborne, we could mostly be gliders, like the albatross. :)

    As a reminder, the mildly deranged penguin offers flight, well, launch, lessons. The trebuchet does most of the hard work, you just glide like a screaming brick…
