Why do I laugh? Laughter is an agressive expression of dismissal and superiority in relation to something or somebody else; by laughing you assert your elevation and confidence and portray yourself as a desirable mate.

Why do I cry? Something happened to you which weakened you and made you a less desirable mate, your body ensures that you associate this experience as a negative one that you may not repeat it.

etc. etc. etc.

All of the above questions have different answers which can be convincing. Why is evolution used above all other theories to explain social phenomena. My guess is that people do it because evolution is a popular theory that has a poweful influence and by using it you appear to have expertise and intellect, thus making you a more desirable mate.
