Following publication of the original article, it came to the attention of the authors that there were errors in Supplementary File 1. Namely, some of the data concerning mean scleral brightness and HC entries for the genus Mustela were incorrect. The species-level value for mean scleral brightness in domesticated Mustela was found to be 128.3 (rather than 107.9) and was 146.93 (rather than 124.6) in the non-domesticated form (M. putorius / eversmanni). Regarding the species-level HC value, this needed to be adjusted to 133.34 (in place of 132.67) for non-domesticated Mustela but had been correctly reported for the domesticated form of Mustela. These errors affected the analyses presented in the article, which were all based on the erroneous dataset in question, as well as the figures, which, as a result of the errors, were inaccurate with respect to data points corresponding to Mustela.

The article original article has been updated to correct the errors in question. In this regard, the authors note that the errors were relatively minimal and that the correcting thereof does not affect the interpretation of the paper’s findings. The results of phylogenetic paired t-tests remain almost unchanged (comparison of domesticated vs. non-domesticated forms -  mean scleral brightness data: t = 0.96, p = 0.36; HC: t = 0.95, p = 0.36) and the effects of eye size on scleral brightness in the initial PGLS model that included the entire species sample remain non-significant (p > 0.325). The authors thank you for reading this erratum and apologize for any inconvenience caused.
