Why are dots in "information … over" being used?

[Odessa Dawn]

Our esteemed teachers:

Yet in the story the Sumerians, who lived in Mesopotamia, in what is now southern Iraq, seemed to understand writing's transformation function. As Dr Holly Pittman, director of the University's Center for Ancient Studies, observed, writing 'arose out of the need to store and transmit information … over time and space'.

​

​

The aforementioned paragraph was taken from "Official IELTS Practice Materials 2." The question, why were three dots in "information … over" being used?


I'd appreciate some inputs on this thread.

This punctuation mark is called an ellipsis.

I means that some of Dr Pittman's words have been omitted.
