lol. Who'd EVER think of dinos turning into birds? 
Anyhow, I don't even think Sligs, Glukkons, Interns, or Vykkers ever even existed in the prehistoric times. Unless their ancient ways of lifes were never recorded, which I guess WOULD mean that they were around in prehistoric times. But, I was more along the lines of back then when Sligs were slugs, Muds were birds, and Gluks were simple octopuses. |
Birds are the most common group of vertabrates around, or at least, the most noticeable. Certainly they are highly successful. Why is it odd some dinosaurs evolved into birds, considering it gave those species an advantage. If the extinction had not occured, pterosaurs almost certainly would have been outcompeted.
I don't think Sligs, Mudokons or Glukkons were necessarily those creatures. Even if they were similar, they technically wouldn't be any of those, since they'd (as far as we know) evolved independently of slugs, birds and octopi on our planet. If Glukkons or Sligs did evolve from creatures like that, that raises the awkward question of where the skeleton appeared from. Certainly Glukkons moreso, with such similar features to those molluscs, considering the Gloktigi is presumably related also.
