Mental Time Travel

Mental time travel (MTT) is  is the cognitive capability of remembering events that already occurred and predicting events that have not occurred yet. There is some indirect evidence of such abilities in nonhuman animals. For example, blue jays (Cyanocitta cristata) are important dispersers of Quercus, Fagus, and Castanea nuts in eastern North America and their caching behavior in the wild has been well documented. Chimpanzees make and use tools for foraging. In some cases they prepare the tools before they reach to the destination. This, however, is within relatively short temporal spans. How far can they imagine times that occurred and times that have not occurred is not known. This is a question open to further studies.
