How do you know it was cargo? I think the film is ambiguous. It was never clear to me whether the aliens were being carried by the ship, or the crew happened to stop in the planet, and find them there in a cave of some sort.
Another detail that creates some doubt is that one of the crew's members was apparently infected and killed by an alien -- why would they carry a cargo that was deadly to them as well?
The fact that the alien parasite could infect humans is not problematic: it had clearly evolved, or been designed, for humanoid hosts. What is less believable is what happens in
Alien3.
My objection to the story would be that the alien parasite seemed to get an awful lot of nourishment from just one human body, which it didn't even consume extensively. The newborn parasite ate very little of its host, who remained alive until the end, and died not from being consumed, but from the violent birth of the alien. Yet that little squirt somehow still managed to grow up to become stronger and taller than a human! Where did it get its proteins from?
But I still like the story.
