The apes beat us in leg strength, too, despite our reliance on our legs for locomotion. Tomonaga and his colleague Tomoko Imura at Niigata University of International and Information Studies in Japan detailed their findings online today (July 16) in the journal Scientific Reports.įollow us, Facebook & Google+. A chimpanzee had, pound for pound, as much as twice the strength of a human when it came to pulling weights. Despite being popular monkey pets, chimpanzees can be very aggressive as well. "How and when do chimpanzee babies acquire such abilities?" Tomonaga asked. Chimpanzees are one of the smartest animals on the planet, and one of the most popular types of apes to be kept as pets. When a black-and-white image of a banana was shown, the chimps took significantly longer to spot the fruit, while no such problem was seen with black-and-white versions of faces.įuture research could explore how well other primates detect faces and at what age chimps learn to quickly detect faces. To outsiders, they have very nasty behaviors. However, further examination showed that the quick ID of the fruit had to do with its distinctive yellow color. They go for the face they go for the hands and feet they go for the testicles. One of the most divergent anatomical regions between these groups is the craniofacial region compared to other apes, humans have a retracted face, high braincase, and small jaws 1. Both species may use facial information for their social lives in the same manner."Ĭhimpanzees also detected a photo of a banana as efficiently as that of a face. Humans and their closest extant relatives, chimpanzees and bonobos, differ in many key morphological aspects. How can we be so similar-and yet so different So Much Alike. These results are quite suggestive when considering the evolution of social intelligence. Humans and chimps share a surprising 98.8 percent of their DNA. "This implies that the face plays a very important social role in both species. Bili ape The Bili apes, or Bondo mystery apes, were names given in 2003 in sensational reports in the popular media to a purportedly new species of highly aggressive, giant ape supposedly inhabiting the wetlands and savannah around of the village of Bili in the Democratic Republic of the Congo. Chimpanzees, for example, have a heavy brow ridge, lack fatty. "Both humans and chimpanzees have developed a specialized ability for face processing," Tomonaga said. Furthermore, the chimpanzee face itself is quite dramatically different from that of humans. Faces seen from the front were more easily detected than faces seen from the side, suggesting that eye-to-eye contact is important for chimps, just as it is in humans. The researchers suggest this gap may result from long-lasting social experiences between chimps and humans. In subsequent experiments, the scientists also found that the chimpanzees efficiently detected the faces of human adults and babies, but were unable to identify monkey faces.

However, the humans recognized the buttocks quickly, whether the photos were upright or inverted. For instance, participants were shown an image of a pair of buttocks, and then they were shown some other photos and were tasked with tapping the original image on a touch screen to indicate recognition.įor humans, the “face inversion effect” was proven to only apply to faces, with inverted face images delaying humans’ recognition. Find high-quality stock photos that you wont find anywhere. Researchers showed both humans and chimpanzees stimuli such as the faces, buttocks - and, as a control, feet - of both humans and chimpanzees.

However, when people see an object such as a house, they recognize it just as rapidly (or slowly) whether or not it is inverted. In the study, the researchers tested chimpanzees’ recognition abilities by using the “face inversion effect” - a phenomenon in which the brain recognizes human faces faster than other objects, but not if those faces are inverted.
