Hm...I'm not sure I'd consider being more mammalian in some ways to be "perfected." Your Skarrats might argue that point!
It's so interesting what different ideas we have, though! My Cardassians actually get insulted by a comparison to reptiles!
(Which is not surprising given that mammalians tend to make that comparison in a derisive manner--claiming they don't have feelings, etc.)
They think of themselves as neither...they would say they have characteristics that belong to both groups, but they think of themselves as something completely
BTW...can you draw a mar'kuu? Please???
