[2] The aim of the research was to produce an animal model of depression.
Homo sapiens × Pan troglodytes. The humanzee (sometimes chuman, manpanzee or chumanzee) is a hypothetical hybrid of chimpanzee and human, thus a form of human–animal hybrid.

Washoe (c. September 1965 – October 30, 2007) was a female common chimpanzee who was the first non-human to learn to communicate using some American Sign Language (ASL) as part of an animal research experiment on animal language acquisition. [1] Washoe learned approximately 350 signs of ASL, [2] also teaching her adopted son Loulis some signs.
Chimpanzees tend to be used repeatedly over decades, rather than used and killed as with most laboratory animals. Some individual chimpanzees currently in U.S. laboratories have been used in experiments for over 40 years. [63] The oldest known chimpanzee in a U.S. lab is Wenka, who was born in a laboratory in Florida on May 21, 1954.
Viki was the subject of one of the first experiments in ape language. Viki was raised by Keith and Catherine Hayes in the same manner as a human infant, to see if she could learn human words. She was given speech therapy, which involved the Hayeses (her adopters) manipulating her lower jaw. Eventually, she was able to voice four words: mama.
Gua was a chimpanzee raised as though she were a human child by scientists Luella and Winthrop Kellogg alongside their infant son Donald. Gua was the first chimpanzee to be used in a cross-rearing study in the US. Gua was born on November 15, 1930, in Havana, Cuba. She was given, along with her mother, Pati, and her father, Jack, to the old ...
