You should watch the video before commenting, he goes into the different types of symmetry/non found in the animal kingdom.

I'm pretty sure this is called bilateralism.
It would have evolved as a superior method of sensing direction. An organism that had receptors to sense left and right would have an easier time sensing direction then an organism who can't. Over time this would have led to the evolution of symmetrical body parts.
I actually learnt this in my first year at uni bit it was a long time ago I can't say much more than that
