![]() ![]() It is believed that each individual has his or her own distinctive pant-hoot, so that they can be easily identified. Almost all primates have five digits on the hand and foot. One well-known chimpanzee vocalisation is called the ‘pant-hoot’. They have a range of vocalisations including barks, hoots and grunts. CommunicationĪ chimpanzee will sometimes hug, pat or brush the face of another chimpanzee to try to reassure them or calm them down. ReflectionsĬhimpanzees are one of the few species that can recognise themselves in a mirror. Among hominins, the degree of curvature observed in the phalangeal shaft correlates with the frequency of arboreal behavior. Don't smile.Ĭhimpanzees use facial expressions to show emotions, but a human smile that shows all your teeth is seen as a threatening expression to chimpanzees. Chimpanzees are capable of eating much larger seeds than most animals in their ecosystem, so many plant species depend on large animals such as chimps to spread their seeds. The seeds then grow into trees in other locations, leading to a healthier tree population. The infants that know human touchhow human hands hold and human fingers tickleare often unfamiliar with chimp social boundaries. Since the thumb is not as long, it just meets up with the palm, while the chimps other four fingers extend upward. Orphaned chimpanzees that have been beaten by humans, isolated for long periods of time, or stuffed into boxes for transport and sale arrive at the sanctuary visibly terrified. When they eat fruit, they spread the seeds of that fruit through their poo. Conversely, chimp hands are much longer and narrower. Chimpanzees hands are very like our own - 4 fingers and an opposable thumb But chimpanzee hands are also perfectly adapted to moving in the trees, Can. Seed dispersalĬhimpanzees play an important role in their environment as seed dispersers. Because of the bitter taste of the plant the chimpanzees’ grimace when they are eating it, it is thought that it is eaten mostly for medicinal reasons rather than taste. An example of this with chimpanzees is when they eat the bitter Vernonia plant, a plant species known to have medicinal benefits. Zoopharmacognosy is the name given a type of ‘animal self-medication’, referring to the phenomenon of animal species knowing the things in their natural environment they can eat to prevent disease, kill viruses or aid digestion. They also use stones to open nuts, and leaves to scoop up drinking water. Different groups of chimpanzees use tools in different ways including using sticks to retrieve termites from their mounds and dig insects out of logs. ToolsĬhimpanzees are one of the few species we know to use tools. ![]() Humans and chimps are believed to share a common ancestor who lived 7 to 13 million years ago. Chimpanzees share over 98% of their genetic material with humans, and along with bonobos, are our closest living relatives. ![]()
