Horses make facial expressions like humans
Just like us, horses too can pucker their lips or raise their chins to convey important messages, new research shows. They use muscles underlying various facial features - including their nostrils, lips and eyes - to alter their facial expressions.The researchers identified in horses 17 discrete facial expressions many of which are similar to humans. The findings suggest evolutionary parallels in different species in how the face is used for communication.

London: Just like us, horses too can pucker their lips or raise their chins to convey important messages, new research shows. They use muscles underlying various facial features - including their nostrils, lips and eyes - to alter their facial expressions.The researchers identified in horses 17 discrete facial expressions many of which are similar to humans. The findings suggest evolutionary parallels in different species in how the face is used for communication.
The researchers analysed video footage of a wide range of naturally occurring horse behaviour to identify all the different movements it is possible for horses to make with their face. They also carried out an anatomical investigation of the facial muscles that underpin these movements. Each individual facial movement that was identified was given a code. Horses share some surprisingly similar facial expressions to humans and chimps, showed the findings.
