What are the functions of tears?When we are tried and yawn, tears come out to wet your eyes. It's useful for me. when i have dry eyes i make myself yawn. and force tears to come out.
But want is the natural purpose of tears? we all know that tears come out went we cry. we cry because we are in pain. or when we are really emotional. either happy or sad. but what function does it perform?
some animals use tears to mark territory.
girls use tears to get their way? boys cry cos they are wimps? hahaha, just kidding.
"we cry when we are extremely emotional" (jot) - Evolution must have a use for that. otherwise it would be there right? something to do with evolving so that we cry when we don't get what we want. or we cry when we fall over and cut our knees.
somehow, those who cried had a survival advantage over those that didn't. or maybe it was an anomaly (something that can't be explained by the theory).
Is it possible that there is a better theory?
Maybe tears make us live longer. As some researcher will tell you. ( research and back anything up). Maybe tears make us more attractive to the opposite sex.
Evolution is such an amazing theory. It explains the evolution of life forms. As long as you are imaginative enough there is a path for every evolution.
