Scleral pigmentation leads to conspicuous, not cryptic, eye morphology in chimpanzees
Researchers of the National University of Singapore and Leiden University have discovered that chimpanzees and bonobos share the contrasting colour pattern seen in human eyes, which makes it easy for them to detect the direction of someone’s gaze from a distance.
