Did we develop the sneezing mechanism to get rid of pathogens like bacteria and viruses in our nose?
Or did pathogens develop a way to make us sneeze to propagate themselves?
Or did we develop the sneezing mechanism, and then pathogens hijacked this pathway to benefit themselves?
I'm trying to understand why we sneeze so much when we get sick - is it our bodies trying to help us, or is it something the pathogen is causing to help itself spread? And if it's both, how did that happen?
