Чантек: Орангутан, освоивший язык жестов и человеческие навыки.

Captive orangutan (1977–2017)

Chantek (December 17, 1977 – August 7, 2017), born at the Yerkes National Primate Research Center in Atlanta, Georgia, was a male hybrid Sumatran/Bornean orangutan who acquired the use of a number of intellectual skills, including American Sign Language (ASL), taught by American anthropologists Lyn Miles and Ann Southcombe. In Malay and Indonesian, cantik (pronounced chanteek) means "lovely" or "beautiful".

Born at the Yerkes National Primate Research Center, Chantek was transferred to the University of Tennessee at Chattanooga (UTC) when he was nine months old. Miles was the director of a research project to study apes, and she and a few student volunteers cared for him the first several months after his arrival. Miles taught him his first signs, "food eat" and "drink". Soon after this her teaching schedule made it necessary to hire an assistant, Ann Southcombe. Ann had experience raising seven baby gorillas at the Cincinnati Zoo and was the first "mother" and "teacher" for Michael, the young gorilla companion to Koko, the first signing gorilla. Under the direction of Miles, Chantek was raised much as a human child yet also had time to be an orangutan. Ann toilet trained Chantek, much as she did Michael. He was given chores, like pick up his toys or sit for a signing test for which he was given an allowance, using steel washers as money. After years of service, she hired a full time assistant to give Chantek all the benefits of early education. As Miles taught anthropology at UTC, she also gathered a group of dedicated student volunteers to help with the project, such as Warren Roberts, who now teaches anthropology classes at the college as of Spring 2017. Chantek spent almost nine years living under constant supervision in a specially adapted trailer on the UTC campus. Chantek made and used tools and even understood the concepts of money and work exchange. He possessed the spatial comprehension to direct a driving route from the University of Tennessee at Chattanooga (UTC) to the closest Dairy Queen, and the mental comprehension to refer to events that happened years ago. He was a huge fan of the country basket at Dairy Queen and enjoyed many Dilly bars. He enjoyed creative projects and made paintings, necklaces, and music. Like children, Chantek preferred to use names rather than pronouns – as the reference is fixed – even when talking to a person. He even invented signs of his own (e. g. 'eye drink' for contact lens solution, and 'Dave Missing Finger' for a special friend).

The term personhood is often ascribed by experts to animals who demonstrate conscious awareness, language, and acculturation. Miles and like minded advocates seek to expand personhood to great apes, to the extent that—eventually—legal rights of personhood would be conferred under the law. To accomplish this goal, Miles created Project Chantek, to further study the mind of the orangutan. She hopes her research will help ascertain how human symbolic systems evolved and developed. Uniquely, her project emphasizes development of cultural models and processes in Chantek's upbringing. Her work is supported by the Chantek Foundation, whose mission is to develop greater scientific understanding of orangutans, to support cultural and language research with orangutans, to promote orangutan conservation and establish culture based great ape sanctuaries, thereby building a bridge of understanding between humans and other great apes. The Chantek Foundation is a member of ApeNet, founded by musician Peter Gabriel to link great apes through the internet, creating the first interspecies internet communication. The project was cancelled.
