Scientists have been communicating with apes via sign language since the 1960s; apes have never asked one question.
apes do not ask questions. Though many express themselves through sign language, they do not use it to question others, a significant cognitive difference between apes & humans (& certain politicians)
However, at least once, a parrot did. He asked what color he was.
Alex the African Grey Parrot: A Revolutionary Bird in Animal Psychology
• Alex the African grey parrot, studied by Dr. Irene Pepperberg, challenged the notion of bird intelligence.
• Through various cognitive exercises, Alex demonstrated abilities comparable to dolphins and primates.
• Alex could recognize colors, objects, materials, and actions, and had a vocabulary of over 100 words.
• He understood the concept of zero and could distinguish objects based on color and material.
• Alex’s groundbreaking achievement was asking an existential question about his own appearance, making him the first non-human to pose a question.
