Holding a Steady Look at the Human Eye: Rebuttal to Critiques of the Gaze-Signalling and Cooperative Eye Hypotheses

2025-10-16

Abstract excerpt

The Cooperative Eye Hypothesis (CEH) and the Gaze-Signalling Hypothesis (GSH) propose that the human eye—distinguished by pronounced scleral exposure and a uniformly white sclera— evolved as a unique trait among primates to enhance eye-gaze visibility and facilitate cooperative communication. A recent review by Perea-Garcia and colleagues (2025) questioned four central premises of these hypotheses: (1) that human...
