In 1970, scientists began researching animals’ ability to recognize themselves in mirrors. While humans are the most well-known for their self-awareness, they are not the only species capable of this skill.
Scientists have tested many different species, from ants to stingrays to African grey parrots, for signs of self-awareness when looking in the mirror. The results have been mixed, with some animals passing the test and others failing it.
Chimpanzees were the first species studied and showed signs of self-awareness. Other great apes like orangutans and bonobos also passed the mirror test, as did an Asian elephant and rats. However, dolphins and magpies have also shown signs of recognizing themselves in mirrors.
Despite these positive results, some species like monkeys and African grey parrots have failed the test. This has raised questions about the true nature of self-awareness in animals and the reliability of the mirror test as a measure of it.
Further experiments on lower animals like ants and fish have also shown some signs of self-awareness in front of mirrors. These results have sparked controversy and raised questions about the significance of the mirror test in understanding animals’ cognitive abilities.
