ELI5: Why do we scream when we are startled or scared?

Recently saw the post about the employee who gets scared by his co workers, and was wondering what is the advantage of screaming when startled.

we're social animals. if one of us gets attacked by a predator, scream bloody murder and everyone else will start shouting and running around as well. scares the predator off, or you can deal with it, or worst case scenario, at least the rest of the tribe know what the predator was, and can take future precautions. it's what most social animals do.
