Meh, it's one of those iconic designs, an EvE ship looks like it, some Centauri cruiser copied the design too, the Vor'cha looks like it, as to a degree - does the bird of prey.
I'm sure you could find other designs that look like it if you tried harder, tracking down the original (which is probably just a bird or something) might be quite hard.
Hell even the batplane VIII looks like it on occasion.
As for the franchise and the series.
I liked Atlantis besides it's failings and ok that's possibly related to my thing for Jewel Staite <3, but, SG-1 was an absolutely amazing series up to the Ori arc, I vaguely questioned the lesser races (I mean us/goa'ulds) ascending but overall it stuck to it's guns, same as Atlantis, the Ori arc bugged the crap outta me but mostly because it was basically Farscape but even worse (POSSIBLE?!).
This one - juries out, but seriously put a recipe together for ultimate tripe "LOST in Space, rather than Lost in Space." (And I didn't think the LOST franchise could be represented in any worse way than it's original seasons did for it).
That said, good first two eps though.
