Recently, I’ve read an article saying that everything on our face is duplicated, including mouth. I imagined myself having two separate mouths. That would be an interesting situation since you can do things like having wine in one mouth and cheese in the other and enjoying the mixed taste without having cheese soaked in the wine. Or you can brush teeth in one of the mouths while eating food in the other. You might be able to whisper better with only one mouth open.

It seems like there are lots of benefits. I wonder what the evolutionary reason for having just one mouth while duplicating many of the other parts.
