Source: Scientific American

By studying the brain activity of a few animals, scientists see some evidence in them of the ability of “episodic memory” or “mental time travel.” This planning of future actions based on past experience is seen as a sign of intelligence. Psychologist Thomas Zentall states that a hint of this ability is apparent in non-human primates, dolphins, scrub-jays, rats, and pigeons.
