Face facts: Even nonhuman animals discriminate human faces

Edward A Wasserman. Learn Behav. 2016 Dec.

Abstract

Humans are commonly believed to have evolved specially adapted neural systems for processing the rich and complex content of faces. However, nonhuman animals-including fish-have also shown a well-developed capacity for discriminating human faces, raising important questions concerning the uniqueness and mechanisms of human face perception.

Keywords: Comparative cognition; Evolution; Face perception; Neural systems.
