In fruit flies, a specific version of the sodium-potassium pump in specialized ear cells is required to maintain the right potassium levels for hearing; without it, the flies become deaf.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review could determine whether Na+/K+-ATPase subunits are universally required for auditory function across invertebrate and vertebrate species.
A systematic review and meta-analysis of all studies using genetic, pharmacological, or physiological methods to assess auditory function in animals with Na+/K+-ATPase mutations or inhibition, including Drosophila, zebrafish, mice, and humans.
An RCT in flies could determine whether restoring ATPα expression rescues hearing loss in knockdown mutants.
A randomized, controlled experiment in 100 Drosophila with ATPα knockdown, randomized to receive transgenic rescue of ATPα expression in scolopale cells or control vector, measuring auditory response (electrophysiology) and scolopale cell potassium concentration (fluorescent sensors).
A cohort study could determine whether ATPα expression levels correlate with hearing sensitivity across fly strains.
A prospective cohort study measuring ATPα mRNA and protein levels in 50 genetically diverse Drosophila strains and correlating them with auditory response thresholds (laser Doppler vibrometry) across a range of sound frequencies.
A case-control study could determine whether flies with deafness phenotypes have mutations in ATPα compared to hearing controls.
A case-control study comparing whole-genome sequencing of 30 deaf Drosophila mutants and 30 hearing controls, identifying mutations in ATPα and other ion transport genes, with functional validation via RNAi.
A cross-sectional study could identify ATPα expression patterns in fly auditory organs at different developmental stages.
A cross-sectional analysis of ATPα expression (immunohistochemistry) in Johnston’s organ of 20 Drosophila at 1, 3, 5, and 7 days post-eclosion, correlating with auditory sensitivity measured by electrophysiology.
