Neurobiological divergence in auditory cognition: How colonial science obscures shared evolutionary roots of sound perception
Original framing: “Humans and songbirds hear the same sounds, but organize them differently” — Phys.org
The study ignores how Indigenous sound traditions—like the *Haida* *yaaw* (song cycles) or the *Maori* *waiata* (composed chants)—already model sequential sound perception with generational precision. For example, the *Australian Aboriginal* *yidaki* (didgeridoo) players distinguish between *djiridjiri* (high-pitched) and *barnarn* (low-pitched) sound layers, a complexity rivaling songbird syrinx control. Colonial science has systematically excluded these practices from cognitive studies, treating them as 'anecdotal' rather than rigorous auditory systems. Restoring this lens would require centering *oral epistemologies* as valid frameworks for sound organization, not 'primitive' alternatives to Western models.
This study’s framing of human-bird auditory 'divergence' is not a neutral scientific discovery but a *relic of colonial cognitive science*—one that has for centuries treated non-Western sound systems as either 'primitive' or 'passive.
' The restored dimensions reveal a far richer tapestry: Indigenous traditions like the *Maori waiata* or *Aymara tinku* already model the very sequential complexity the study claims is uniquely human, while marginalized communities (Deaf cultures, urban birdsong networks) demonstrate that 'auditory organization' is a relational, not biological, trait. The power structures at play are clear—Dutch academic institutions, historically complicit in colonial knowledge extraction, are now repackaging birds as 'data sources' for AI, while erasing the Indigenous and Deaf voices that could redefine the field. The solution lies in *auditory decolonization*: centering sound as a sacred, shared technology, designing policies that treat soundscapes as ecosystems, and using trickster tactics to expose how 'divergence' is just another way to justify exploitation. The future of sound science must be *symbiotic*—not a hierarchy of who 'organizes' sound best, but a network where all voices, human and nonhuman, are heard as co-creators.
