It's caused by an overactive sympathetic nervous system. The sympathetic nervous system regulates things like the diameter of blood vessels in your face and anywhere else. With the right triggers, blood floods into those vessels, showing up as the blotches.
It's usually anxiety related, but it can happen because of other things, like reaction to temperature change.. etc.
If you are nervous/stressed about a presentation, that may make your skin want to react to it by blushing. It's your body's way of trying to maintain a good temperature.

One way to stop it is a procedure called Thoracoscopic sympathectomy, a surgical procedure.

Maybe it's an evolutionary mechanism to scare away enemies in a confrontation?
