Why all this newtype discussion?

It seems pretty clear to me that SEED "newtypes" are empaths, people capable of sensing the emotions of others. No mind reading, now precognition, just emotions.

For example, Kira knew Cagali was crying. He could sense her emotional state.

Dont get me wrong, with enough experience at reading emotions, it could have incredibly valid combat application. You feel a sudden increase in aggresion? Theres a warning that your opponent is about to attack.

As far as recognizing others at a distance... well, I'm sure thats not too hard to do based on emotions.
