‘Uniquely human’ muscles have been discovered in apes

Muscles believed to be unique to humans have been discovered in several ape species, challenging long-held anthropocentric theories on the origin and evolution of human soft tissues. This questions the view that certain muscles evolved to provide special adaptations for human traits, such as walking on two legs, tool use, and sophisticated vocal communication and facial expressions. The findings highlight that thorough knowledge of ape anatomy is necessary for a better understanding of human evolution.
