Redshift ∼2.7 is not special

Galikyan et al. (2025, A&A, 696, L21) reported a statistically significant change in galaxy spectral properties at redshift z ≃ 2.7 based on a Kolmogorov Stochasticity Parameter analysis of JWST spectroscopic data of galaxies. In this comment, we demonstrate that this result is critically driven by a single outlier in the dataset that was employed. This outlier arises from the use of a questionable redshift estimate for one spectrum. When the outlier is removed or the redshift is corrected, the claimed transition at z ≃ 2.7 disappears entirely. By independently reproducing the previous analysis, we demonstrate that the claimed feature is not a robust statistical signal, but an artefact of this anomalous data point.
