Emotional tears could be an evolutionary adaptation. This form of eye-moistening is not just a means of survival. Studies have shown that our ancestors could have used it against predators by making it harder for them to tell where we were gazing. Also, it could be a way to show our vulnerability, that we prefer peace instead.
When we see someone crying, our instincts often tell us to ash what is wrong. We almost always offer empathy. Our emotional tears could be a signal to be trusting and become bonded.
