IIRC,Stephen Pinker discusses the subject in "How the Mind Works", with references for
further reading.

V.S. Ramachandran also addresses this in Phantoms in the Brain. He suggests that it evolved as a
signal when a perceived threat turned out to be trivial. That's what makes something humorous:
the punchline is more trivial than the expected outcome of an otherwise serious (or mundane)
plot line.

The reason for laughter and humour having evolved is a fundamental opportunity (for individuals) to
cope with life-situationally concurrent and past adversities (that causes neuropsychophysiological
tension) in an tension releasing (relatively safely and enjoyably - and even socially 'cementingly'
and conflict 'preventingly' - so) way.

evolutionary opportunity; and the potential for doing/having "it" is THE most basic "opportunity-
type evolutionary pressure" that I can think of.)

This is my own so it's highly tentative hypothesis. But you use the same facial muscles to smile as
to chew and eat - and vice versa the same muscles to frown as to block out food or spit it out. It's
conceivable that these are food signals IMO
