Cultural revolution in whale songs

Nature, 2000
Songs of the east Australian humpback population were recorded across successive breeding seasons while a small number of whales carrying the quite different song of the west Australian population appeared in the area.
- Studied in
- Megaptera novaeangliae
- Sample size
- songs recorded off eastern Australia across several seasons
Within two seasons the entire east Australian population had abandoned its own song and adopted the western one, essentially wholesale rather than by gradual blending.
What it means
The authors' reading, and ours. Where they differ, that difference is the point.
How the authors put it
The rapid, complete replacement of a population’s song by that of a few immigrants is cultural transmission on a population scale.
How NatureHQ reads it
Among the cleanest demonstrations of animal culture that exists, because of how badly it fits any alternative. A song replaced across a whole population inside two years is too fast for genetic change and too complete for independent invention, and the direction of the change points at a handful of arriving animals. The unresolved part is why: whatever makes a novel song attractive enough to displace the resident one is not established, and the finding is often reported as though it were.
- A single, effectively unrepeatable natural event.
- Why the incoming song spread — novelty, or something about the singers — is unexplained.
- The function of song itself remains uncertain, which limits what any change in it can be taken to mean.
