Various modulation of various parameters over time. That's how you make it evolve and breath, if that's the answer you are looking for.
edit: Speaking of which, I'm making short loops of roomtones to be looped in a game, and it's actually pretty hard to find a nice "clean" loop that will end up sounding like a natural ambience. The brain will recognize the most subtle repetition/variation and identify it as a loop. So I started making roomtone-loops a little longer, because I can spot the loops even with my eyes closed.
Not all short loops need to change over time to sound good. Strictly speaking if we're talking about audio loops they cant change over time, so modulation is out.
I think a lot of the time it's context and environment. I.E the genre you're writing and the other sounds in the mix. Put a super short 2 beat loop in a hypnotic and atonal techno tune and it will sound great, then try and put that same loop in a hip hop pop song and it will sound terrible.
I've found you can get more mileage from a loop if it's weirder or harder to unpack, because it will take more time to become familiar and monotonous/grating. One of the reasons I love the more IDM/experimental side of electronica.

I had to do crowd noise for a game I worked on a few years back, and it was really hard to get things to not sound repetitive. Especially if there is any easily identified audio gesture. It took me weeks to get them sounding 'natural'. Random selection of shorter loops to create a longer one works for this type of thing.
Although this really had nothing to do with the topic as I imagine he was talking about music and not ambience.

Yeah, I can relate. I'm making a loop out of a waiting room in a hospital and it's a bit of a PITA.
I thought of it, most loop variation/evolution are quite predictable.
Sometimes I can guess how and when a loop variation will be applied at first track listening simply by the context.
Maybe predictability is somehow good in dance music.
Another possibility is that a tone variation every three bars is too repetitive to my ears.
Or maybe thinking by multiples of 4 is innate in dance music.

I faced a similar problem when thinking about how to make a dynamic loop of engine sound samples, but I never really tried to solve it.
Back on topic:
basically every variation increase the real length of the loop, so is like a sort of cheating if we were strictly talking of short loops.
I wonder if would be possible trick the listener thinking that variations never happened and at the same time break the repetitiveness.

Reason: typo
changes in velocity, a slight variation that makes it not just straight ahead. changing things around it like a different pad coming in, something dropping out. It's amazing how something can seem like it's moving just by changing the surroundings.
