The disappearance of Ai, known internationally as a gifted chimpanzee, implies the closure of one of the most influential lines of research on animal cognition of the last half century. Since his arrival in Japan in the late 1970s, his life was linked to scientific studies that explored memory, perception and learning in non-human primates. The case of this animal was relevant not only for its experimental results, but also for the method applie…
Chimpanzee who could paint and count dies at 49
A chimpanzee who could understand the English alphabet and more than 100 Chinese characters died, aged 49. Ai arrived in Kyoto, Japan, as a baby, and became the center of hundreds of scholarly papers; as well as reading, she could count, identify colors, and draw and paint. The discovery of language skills in great apes — various gorillas and chimps learned substantial vocabularies in sign language or symbols — and that of tool use across the an…
Japanese researchers have announced the sad news that Ai, a chimpanzee who recognized more than a hundred Chinese characters and letters of the Latin alphabet, has died at the age of 49. Her extraordinary abilities earned her the label of a genius.
