In 1970, research on animals’ ability to recognize themselves in mirrors began. It was discovered that humans were not the only species capable of this ability. Scientists have tested various species, from ants to stingrays to African grey parrots, for signs of self-awareness when looking in the mirror.
Chimpanzees were the first species studied and showed signs of self-awareness. Other great apes like orangutans and bonobos have also passed the mirror test, as well as an Asian elephant and rats. Dolphins and magpies have also shown signs of recognizing themselves in mirrors.
However, some species, such as monkeys and African grey parrots, have failed the test. This raises questions about the true nature of self-awareness in animals and the reliability of the mirror test as a measure of it. Experiments on lower animals like ants and fish have also shown some signs of self-awareness in front of mirrors. The results of these experiments have sparked controversy and raised questions about the significance of the mirror test in understanding animals’ cognitive abilities.
