Maybe it's the same sort of thing that they developed their mating and hunting "rituals" by. Somehow their brains "mark" the connection between how many times they spin or rock or "head-jive" and when the food "comes out" again. If something they needed ,like food, seemed to appear and reappear, that would be a good way to mark "time" so they could be ready to snatch it before competitors did. As time went on, maybe the youngest generation had a "built-in" catalog in their brains of "food-catching" time-marking movements that were passed on by their ancestors. Females would logically become interested in a display of repeated movements that had the most differences from the ones they "knew" that would increase their food availability for their survival.
