Does the MacBook Pro with Retina display have a stereo mic input?

I want to record two tracks (stereo) on my new MacBook Pro. Before I buy the splitter and two microphones I have this question:

Can I just plug it into the mic/headphone jack or do I need a special adapter?

And more importantly:

Is the headphone jack mono in or stereo input?
