The chimpanzee, also known as simply the chimp, is a species of great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed one. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing 40–70 kg (88–154 lb) for males and 27–50 kg (60–110 lb) for females and standing 150 cm.
The bonobo, also historically called the pygmy chimpanzee and less often the dwarf chimpanzee or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus Pan, the other being the common chimpanzee. While bonobos are now recognized as a distinct species in their own right, they were initially thought to be a subspecies of chimpanzee due to the physical similarities between the two species. Taxonomically, the members of the chimpanzee/bonobo subtribe Panina are collectively termed panins.
The genus Pan consists of two extant species: the chimpanzee and the bonobo. Taxonomically, these two ape species are collectively termed panins. The two species were formerly collectively called "chimpanzees" or "chimps"; if bonobos were recognized as a separate group at all, they were referred to as "pygmy chimpanzees". Together with humans, gorillas, and orangutans they are part of the family Hominidae. Native to sub-Saharan Africa, chimpanzees and bonobos are currently both found in the Congo jungle, while only the chimpanzee is also found further north in West Africa. Both species are listed as endangered on the IUCN Red List of Threatened Species, and in 2017 the Convention on Migratory Species selected the chimpanzee for special protection.
Twycross Zoo is a medium to large zoo near Norton Juxta Twycross, Leicestershire. The zoo has the largest collection of monkeys and apes in the Western World, and in 2006 re-launched itself as "Twycross Zoo – The World Primate Centre".
Yerkish is an artificial language developed for use by non-human primates. It employs a keyboard whose keys contain lexigrams, symbols corresponding to objects or ideas.
Franciscus Bernardus Maria "Frans" de Waal is a Dutch primatologist and ethologist. He is the Charles Howard Candler Professor of Primate Behavior in the Department of Psychology at Emory University in Atlanta, Georgia, director of the Living Links Center at the Yerkes National Primate Research Center at Emory, and author of numerous books including Chimpanzee Politics (1982) and Our Inner Ape (2005). His research centers on primate social behavior, including conflict resolution, cooperation, inequity aversion, and food-sharing. He is a member of the United States National Academy of Sciences and the Royal Netherlands Academy of Arts and Sciences.
Animal languages are forms of non-human animal communication that show similarities to human language. Animals communicate through a variety of signs, such as sounds or movements. Signing among animals may be considered complex enough to be a form of language if the inventory of signs is large. The signs are relatively arbitrary, and the animals seem to produce them with a degree of volition. In experimental tests, animal communication may also be evidenced through the use of lexigrams by chimpanzees and bonobos.
Kanzi, also known by the lexigram , is a male bonobo who has been the subject of several studies on great ape language. According to Sue Savage-Rumbaugh, a primatologist who has studied the bonobo throughout her life, Kanzi has exhibited advanced linguistic aptitude.
Research into great ape language has involved teaching chimpanzees, bonobos, gorillas and orangutans to communicate with humans and with each other using sign language, physical tokens, lexigrams, and mimicking human speech. Some primatologists argue that these primates' use of the communication tools indicates their ability to use "language", although this is not consistent with some definitions of that term.
Von Economo neurons (VENs), also called spindle neurons, are a specific class of mammalian cortical neurons characterized by a large spindle-shaped soma gradually tapering into a single apical axon in one direction, with only a single dendrite facing opposite. Other cortical neurons tend to have many dendrites, and the bipolar-shaped morphology of von Economo neurons is unique here.
Lana was a female chimpanzee, the first to be used in language research using lexigrams. She was born at the Yerkes National Primate Research Center of Emory University, and the project she was allocated to when 1 year old, the LANguage Analogue project led by Duane Rumbaugh, was named after her with the acronym LANA because the project team felt that her identity was well worth preserving.
Emily Sue Savage-Rumbaugh is a psychologist and primatologist most known for her work with two bonobos, Kanzi and Panbanisha, investigating their linguistic and cognitive abilities using lexigrams and computer-based keyboards. Originally based at Georgia State University's Language Research Center in Atlanta, Georgia, she worked at the Iowa Primate Learning Sanctuary in Des Moines, Iowa from 2006 until her departure in November 2013. She currently sits on the Board of Directors of Bonobo Hope.
Azy, is a male hybrid orangutan. He was born on December 14, 1977 at the National Zoo in Washington, D.C. He was transferred to the Albuquerque Zoo in 1978, and returned to the National Zoo in 1980.
Ape Cognition and Conservation Initiative is a sanctuary and scientific research facility in Des Moines, Iowa. It is dedicated to understanding the origins and future of culture, language, tools and intelligence. The facility was announced in 2002 and received its first ape residents in 2004, and is currently home to a colony of seven bonobos involved in non-invasive interdisciplinary studies of their cognitive and communicative capabilities.
William M. Fields, also known by the lexigram , is an American qualitative investigator studying language, culture, and tools in non-human primates. He is best known for his collaboration with Sue Savage-Rumbaugh beginning in 1997 at the Language Research Center of Georgia State University. There he co-reared Nyota , a baby bonobo, with Panbanisha , Kanzi and Savage-Rumbaugh . Fields and Savage-Rumbaugh are the only scientists in the world carrying out language research with bonobos.
Nyota is a given name. It means star in the African languages Swahili and Lingala.
Panbanisha, also known by the lexigram , was a female bonobo that featured in studies on great ape language by Professor Sue Savage-Rumbaugh. Her name is Swahili for "to cleave together for the purpose of contrast."
Human Ape is a 2008 National Geographic documentary film on the genetic and evolutionary origins of human behavior, and covers the genetic and behavioural similarities and differences between humans and other great apes. The award-winning independent production company Pioneer Productions of London was commissioned by National Geographic Channels International to produce Human Ape.
Panpanzee the chimpanzee, was born at the Language Research Center at Georgia State University in Atlanta, Georgia. She lived the rest of her life at the Great Ape Trust in Iowa. Her half-brother is Kanzi, a famous bonobo. Kanzi learned 348 lexigram symbols and over 3,000 words from the English language over her lifespan.
, is a bonobo. Nyota was born at the Language Research Center at Georgia State University. His mother was Panbanisha and his father was P-suke. With Panbanisha's death on November 6, 2012, Nyota became the sole surviving member of his immediate family.
