This behavior was first observed in primate studies, with gorillas showing varying levels of recognition. While great apes like chimpanzees and bonobos often pass the "mirror test" by touching marks on their bodies only visible in the reflection, gorillas have more inconsistent results. Some succeed, while others show less interest or confusion.
The ability to recognize oneself in a mirror suggests complex cognitive processes, including self-recognition and an understanding of individuality. It highlights the intelligence of gorillas, their capacity for self-reflection, and their similarity to humans in terms of social and emotional awareness. This behavior not only deepens our appreciation for these majestic animals but also opens windows into the broader concept of animal consciousness.
