I read on the BBC awhile back about the evolutionary development of dragons. If dragons were/are real, they would have to meet particular designs (some imposed by the limits of our imaginations, and some imposed by gravity).
One issue of discussion: Dragon hands. As most flying animals developed their wings, they developed them from their front forelimbs.
Thus, dragons having wings AND front forelimbs seemed highly unlikely in our understanding of evolutionary development.
That does not deter me from the feasibility of dragons. Rather, it makes me wonder…who needs claws, when you have wings?
Keep creating,
