Mental time travel refers to the ability to recall a past event and imagine the future. Some researchers claim that this ability is unique to humans, while others argue that nonhuman animals also possess this ability. A study on apes by using eye-tracking revealed that chimpanzees and bonobos can remember a single event for 24 hours, suggesting that they possess at least some elements of mental time travel.
