Facial expressions evolved as an adversarial attack on the emotion modeling of other people. Facial emotion recognition and the archetypical emotional expressions co-evolved to compensate for these attacks.

The basic idea is that once we began looking at each other's faces and poses to guess mental states and attitudes towards us, the others evolved to produce facial expressions that would fool us about this, for instance making a selfish child look angelic.

Then the observers evolved to correct for this, and a certain set of facial expressions that would express evolved exaggerations or signaling patterns was expected as normal (like the contemporary toothy smile as a signal for not-unfriendliness, or not-desolateness).

Then the emotion signalers evolved to manipulate these expressions to express that the deviations that careful observers could recognize within the standard grimaces would show the "true" emotions, which leads to more fine-grained observation and a whole symbolic facial language.

I am sorry, I am not a natural at reading grimaces, and I am also not as interested in producing facial expression as I am in understanding the mechanisms that produce them. The hypothesis I wrote above popped up in my mind today and wanted to be shared, because it is delicious.

Yes I can definitely tell this idea popped into your head ...and may have even struck you. You might want to press charges and see if you can catch the culprit. It's ridiculously horrible.

I am mostly interested in whether it is true. I am not sure if you can see such questions clearly, because your priorities may be different. But I think you succeed in being funny and expressive!

It could be my priorities yes but flattery will get you no where. And it could be that these ideas are a bit premature. Maybe this recipe calls for a smidgen more marination? Think about it.
