apes are considered knuckle walkers with evident brachiation. The most notable difference in physical features is the split hairlines found in bonobos in contrast to the flat hair Chimpanzee. Average lifespan of both apes are quite close with Bonobos having a slightly lower average lifespan of 40 years while Chimpanzee can live up to 40-50 years (Lang KA‚ 2010). Perhaps the most different trait of each primate is how much physical deviation is between the genders. Sexual dimorphism is more apparent

Introduction: The Arnhem chimp colony had about 25 individuals housed in an outdoor enclosure of almost two acres. Partially wooded‚ the enclosure has a mixture of live trees protected by electrical fencing and dead ones. Over a hundred recurring gestures and recurring signals have been observed in Arnhem‚ all of which have also been seen in the wild. One of the phenomena that makes aggression‚ social behavior

thought the best animal for this would be a chimpanzee. The Gardners bought a chimp and named her Washoe. After being with Washoe for a while‚ and doing many experiments to try to communicate with her‚ they decided that ASL would be the best way to communicate (Patent 116). In A little over four years‚ Washoe used one hundred thirty-two signs. She new different signs‚ such as flower‚ doll‚ mine‚ dirty‚ good‚ listen‚ and so much more (Patent 118). Washoe would use her signs to have conversations with

Birds‚ bees‚ bats‚ apes‚ worms‚ even humans have a communication system. We all share the art of language in one form or another. Some scientists say that language is what sets humans apart from every other species. Other researchers wonder if animals can learn the human language. What sets us apart from animals? What set us apart are the rules and grammars that we human have‚ which makes it not possible for animals to learn the human language. Another factor that contributes to why animals cannot

Are apes capable of using the language? During the recent time frame scientists have shown that such mammals as chimpanzees‚ gorillas‚ and orangutans are capable of learning and using ASL (American Sign Language) and several artificial languages like‚ for example‚ «Yerkish.» However‚ there is a controversy in how far that ability of great apes spans. There are two different groups of researchers‚ experimenting with language and apes‚ those who are in favor of a «traditional» approach‚ and those

Bever (1979) argued that the apes in language experiments were not using language spontaneously‚ but were merely imitating their trainers‚ responding to conscious or unconscious cues. Terrace and his colleagues at Columbia University had trained a chimpanzee‚ Nim‚ in American Sign Language‚ so their skepticism about the apes ’ abilities received much attention. In fact funding for ape language research was sharply reduced following publication of their 1979 article "Can an Ape Create a Sentence?" In

In 1965‚ a peculiar chimpanzee was the center of attention as scientists utilized American Sign Language in hopes of communicating efficiently with another species. The female chimpanzee was named Washoe. While this was by no means a quick study‚ scientists patiently taught Washoe for years and by the time she was an adult‚ Washoe had been about to spontaneously and appropriately use 350 different signs. It is still under much controversy that she could effectively use this language in complex sentences

David Greybeard took a stick‚ ripped the leaves off and used it to fish for termites. Another incident‚ when Goodall was trying to give a banana to Mike and he was too nervous to get it from her hand‚ he then grabbed a stick and knocked the banana off her hand (Goodall 2000:19).
