Chimpanzees and humans have many things in common when it comes to facial expressions and facial structure; however, they also have many significant differences! Below is a series of imagery focusing on an action affected by the prominent brow ridge seen in chimpanzees: brow raiser – a frontalis action. Observe the key differences and similarities.

Currently learning chimpanzee FACS, chimpanzee anatomy, and making custom chimpanzee landmark diagrams. (Chimpanzee landmarks determined by Animal FACS group. Original research work by Lisa A Parr, Bridget M Waller, and Jennifer Fugate. See: Emotional communication in primates: implications for neurobiology )
