Spider/Cobwebs

[Isaac.T]

So I was just watching SGA S01E12 and I knoticed when they entered the 10k year old wraith ship there were spider webs and Cobb webs everyone. I have often noticed this in other shows and movies as well... My question is who made the assumption there are spiders on other planets let alone other galaxies and why would the be on alien ships...?

Whoever was responsible for the sets, I would guess.

Cobwebs always do have that creepy feeling about them... especially when you walk straight into one face first.

Might not have been spider webs, the ships are organic, probably just some whispy bits from it

[Pharaoh Hamenthotep]

Maybe they're Iratus Bug webs? Or bits of Wraith webbing. We have seen them cover victims in webbing, and use it to build cocoons into the walls of the ships to store humans to feed on them in the future.

And we saw an iratus bug web up shepard..

When there are living creatures on a planet then there must be a kind of cobwebbing living thing! And in spaceships stowaways can lead a secret life - once abandoned the spiders or spider-like creatures take over.
Like FH said - cobwebs give a tingling feeling!

Someone who realized that travelers from Earth had been to that planet before?

The people from Atlantis came from Earth 5-10 million years ago where there were living spiders. It's not unreasonable to think that they brought stowaway spiders with them to Lentea. It then should go without saying that they would have explored the only other habitable planet in their solar system and so spiders could have stowed away yet again and then, millions of years later, found their way onto the Wraith's ship.

Not to mention that the Ancients were known to have engaged in quite a bit of terraforming and may have purposely introduced more than just human animal life to alien planets.

Stargate is one of the few exceptions in science fiction where it's not only excusable to have a lot of carryover of animal and plant life on various planets, but it's to be expected.

First, you have the Stargate itself which has been used to allow people to just about instantaneously travel between planets for millions of years. The potential for plant spores, insects, insect eggs, etc., to stealthily hop a ride on people's clothing is tremendous. On top of that, there are a ton of reasons why people would purposely bring forms of life through the Stargate with them. For example, if you're the Goa'uld and you're moving human slaves to other planets in the Milky Way, they need to eat so it's only natural that you would send crops and already domesticated animals for their use on this new planet you're settling them on.

Second, you have multiple species purposely terraforming worlds for the benefit of human life. That includes the Ancients, who are the first evolution of humanity, and the Goa'uld who inhabit human hosts (Teal'c once said they terraform worlds, btw). These are convenient/inventive explanations for why human actors are being used to portray aliens but they also work to explain why worlds are so similar as both groups were likely to have purposely taken life from Earth and brought it elsewhere. In the case of the Ancients, this also means from the Milky Way galaxy to the Pegasus galaxy.

Third, you have a whole lot of past instances of ship travel going on between Earth and planets that had contact with Earth prior to the rediscovery of the Stargate, which further increases the likelihood of small forms of life hopping a ride from planet to planet. And with primitive races getting their hands on ship technology (thanks to the Stargate) and how the idea of protecting native environments from foreign influence is already shot thanks to the gate system (plus the aforementioned purposeful transfer of lifeforms) ships understandably don't have the kind of screening process you might expect in another setting.
