These cells might be important for understanding feelings and social interactions. There are special cells called von Economo neurons in certain parts of the brain, like the anterior cingulate and frontoinsular cortex, that are found in both chimpanzees (and other great apes) and humans.These areas are located in similar parts of the brain in chimpanzees as they are in humans. They have areas in their brains that are like Broca's and Wernicke's areas in humans, which help with language and understanding speech.There are a few other interesting things about chimpanzee brains that are similar to human brains: Chimpanzees take a long time to grow up, like humans do, during which they learn to socialize and their brain structure can be influenced significantly by what they experience and learn.Ĭhimpanzee brains have a very folded neocortex, which is related to their relatively large size. This happens because their brain structure and function are quite similar. The neocortex includes a set of regions, called the association cortex, that are active during advanced cognitive skills like using language, understanding social interactions, and solving problems.Įven though humans and chimpanzees have differences, they also share many ways of thinking, communicating, and feeling. This size difference mostly comes from the neocortex, a part of the brain that has expanded substantially in humans. Through studying their shared evolutionary and genetic heritage, we gain valuable insights into the complex web of relationships that connect humans to these remarkable primates.Ĭhimpanzee brains are about one-third the size of human brains. Habitat range in the wild: Equatorial Africa, from southern Senegal across the forested belt north of the Congo River to western Uganda and western Tanzaniaīody weight: 40 to 60 kg (M), 32 to 47 kg (F)Ĭhimpanzees, along with other great apes such as bonobos, gorillas, and orangutans, are among humans' closest living relatives. Life span: 40 to 45 years (wild), more than 60 (captive) verusĬonservation status: Endangered ( IUCN Red List)
