A good rule for the colony ships.

Probably up there with having sex with aliens, they might mate like anglerfish.

Still worth it.

I'd guess that any habitable planet will have life.  Our atmosphere will react with about anything including itself, it needs life to maintain the levels of oxygen.  Any landing we make will may alter any sort of evolutionary course.  Just wondering if we'd even care about future possible lifeforms.  Maybe it'd depend on how awesome we make space stations.

Yes, due to the nature of planetary oxygen production, if it's habitable it will have life.

How do you define "habitable"? Because the presence of oxygen and earth-like temperatures doesn't necessarily guarantee the existence of any of the other building blocks of life (even though bacteria did play an enormous part in providing out own atmosphere with free elemental oxygen)

So some people have genes that make these damn things.

Everyone does, pr else they wpuldn't work. What some people don't have is a means of folding the protein into other configurations

Trying to think of scenarios where oxygen would stick around.  Oxygen and noble gas combo? 

[Mesozoic Mister Nigel]

You're really gonna need life of some sort to get physiologically relevant quantities of atmospheric oxygen.

[Mesozoic Mister Nigel]

I mean, there is also the hypothetical possibility of high-surface-titanium planets, but the likelihood of a high-surface-titanium planet being otherwise inhabitable seems low.

Okay so now I'm freaked the fuck out about this prions shit. I think we may owe it to the world to spread mass-panic

Already happened; remember Mad Cow Disease?

Literally why I tell people cannibalism is bad.

If a noble gas /had/ to share electrons with something, it would probably choose oxygen.  Otherwise, I think O₂ is a decent scenario, or we could lock it in carbon and send in oxygen releasing "plants" prior to arrival.  Worst case scenario, we get it from water by electrolysis.  Oxygen rules.
