In a recent study, it was revealed that apes, our closest living relatives, exhibit the remarkable ability to recognize both family members and long-lost friends even after enduring decades of separation. The investigation involved 26 captive chimpanzees and bonobos sourced from various zoos globally. These primates were presented with images depicting former groupmates alongside pictures of unfamiliar apes. The results not only validated but also provided concrete evidence for what primatologists have long conjectured regarding the cognitive capacities of these intelligent creatures.
