McKAY: But I thought you already said they had a number of genetic characteristics similar to humans.
BECKETT: They do — but they’re still much closer to the bug creature that attacked Major Sheppard than to us.
So… if Wraith are closer to Iratus bugs than to human, then
why do Wraith not have endoskeletons?
why do Wraith have mammalian hair?
why do Wraith Queens have mammalian breasts?
why do Wraith only have 2 legs and walk bipedal?
why do Wraith not have long tails?
why do Wraith not have wings?
Is there a script doctor in the house?!
