"Instead, the researchers found that surface variations in chitin filtered out the iridescence. Remaining colors proved to be stable, and were visible from almost any angle. They differed consistently between species and sex."
Bill, the basic factor in most humor is incongruity. We laugh when things turn out to be different from what we expect. In this case, the story starts off as a romance, then turns into a cliff-hanger (literally), then all the sudden the result turns on the fact that the man is bald. That is incongruous; therefore liable to elicit a humorous reaction in the audience.
Of course, only if the audience is open to the experience. I'm very sorry you didn't find it funny, and I apologize for wasting 35 seconds of your time.
