[Star Wars] Why are so many members of the Rebel Alliance human?

Watching the documentaries I noticed that all of the regular soldiers are humans, why are so few alien Rebels? Are they all specialists like the Bothans?

Humans make up a large fraction of the galactic population, so maybe it's just reflective of that.  Also, non-humans would stand out more to the bigoted Imperials; they might be more likely to be investigated and less able to hide in the shadows.  The rebels probably rely on stealth and hiding a fair bit.
