The chimpanzee, also simply known as the chimp, is a species of great ape native to the forests and savannahs 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 thus 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, is an endangered great ape and one of the two species making up the genus Pan. While bonobos are, today, recognized as a distinct species in their own right, they were initially thought to be a subspecies of Pan troglodytes, due to the physical similarities between the two species. Taxonomically, members of the chimpanzee/bonobo subtribe Panina—composed entirely by the genus Pan—are collectively termed panins.
Neam "Nim" Chimpsky was a chimpanzee and the subject of an extended study of animal language acquisition at Columbia University. The project was led by Herbert S. Terrace with the linguistic analysis headed up by psycholinguist Thomas Bever. Within the context of a scientific study, Chimpsky was named as a pun on linguist Noam Chomsky, who posits that humans are "wired" to develop language.
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 de Waal was a Dutch-American primatologist and ethologist. He was 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 centered on primate social behavior, including conflict resolution, cooperation, inequity aversion, and food-sharing. He was a member of the United States National Academy of Sciences and the Royal Netherlands Academy of Arts and Sciences.
Animal languages are forms of communication between animals that show similarities to human language. Animals communicate through a variety of signs, such as sounds and movements. Signing among animals may be considered a form of language if the inventory of signs is large enough. The signs are relatively arbitrary, and the animals seem to produce them with a degree of volition.
The Great Ape Project (GAP), founded in 1993, is an international organization of primatologists, anthropologists, ethicists, and others who advocate a United Nations Declaration of the Rights of Great Apes that would confer basic legal rights on non-human great apes: bonobos, chimpanzees, gorillas and orangutans.
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 each other using sign language, physical tokens, lexigrams, and imitative human speech. Some primatologists argue that the use of these communication methods indicate primate "language" ability, though this depends on one's definition of language. The cognitive tradeoff hypothesis suggests that human language skills evolved at the expense of the short-term and working memory capabilities potentially observed in other hominids.
Von Economo neurons, 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 use lexigrams in language research. 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.
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. Pioneer Productions of London was commissioned by National Geographic Channels International to produce Human Ape. Human Ape was executive produced by Stuart Carter and directed by Martin Gorst. distributed by National Geographic Channel and Granada International.
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.
