Is the waggle dance a language?
Short answerIt depends
It depends entirely on what the word is doing. The dance demonstrably encodes two continuous variables that a receiver can act on, which is communication by any definition. It has not been shown to be compositional, to refer to anything beyond that vector, or to be produced with intent — and language, to most readers, implies all three.
Where the belief comes from
Von Frisch called it a dance language and the term is embedded in the literature. He was making a specific point about symbolic encoding rather than claiming syntax, and the phrase has carried much more freight in popular use than he attached to it.
What is settled
That the dance carries direction and distance, that recruits use that information, and that the encoding involves an abstraction — a solar bearing represented as an angle from vertical on a dark comb. All three are established, the third most clearly by the comparison with open-nesting species that point directly at the target instead.
The controversy, and how it ended
From the 1960s a serious challenge argued that recruits were not using the dance at all — that they left the nest and found food by odour, and the correlation between dance and arrival was an artefact of dancers and recruits sharing scent cues. That was a reasonable objection and it took thirty years to answer properly. Harmonic radar tracking of individual recruits answered it: they fly the encoded vector, including when displaced so it points somewhere unfamiliar.
What has not been shown
- Compositionality: no evidence that dance elements combine to produce new meanings.
- Reference beyond the encoded vector and the resource type.
- Intent: nothing in the work shows a dancer performing in order to inform.
- Comprehension: followers extract a vector with measurable error, and many extract nothing usable.
