Knowledge of and planning for the future is a complex skill that is considered by many to be uniquely human. We are not born with it; children develop a sense of the future at around the age of two and some planning ability by only the age of four to five. According to the Bischof-Köhler hypothesis, only humans can dissociate themselves from their current motivation and take action for future needs: other animals are incapable of anticipating future needs, and any future-oriented behaviours… 
Ravens parallel great apes in flexible planning for tool-use and bartering
TLDR
It is shown that ravens plan for events unrelated to caching—tool-use and bartering—with delays of up to 17 hours, exert self-control, and consider temporal distance to future events, which suggests that planning evolved independently in corvids, which opens new avenues for the study of cognitive evolution.
A raven's memories are for the future
TLDR
It is shown that ravens anticipate the nature, time, and location of a future event based on previous experiences, and this results suggest that planning for the future is not uniquely human and evolved independently in distantly related species to address common problems.
vidence for future cognition in animals illiam
Evidence concerning the possibility of mental time travel into the future by animals was reviewed. Both experimental laboratory studies and field observations were considered. Paradigms for the study
No evidence for future planning in Canada jays (Perisoreus canadensis)
TLDR
Canada jays showed no evidence of future planning and instead cached in the location where food was usually available, opposite to the behaviour described for California scrub-jays, adding to the recent debates about the role of complex cognition in corvid caching strategies.
Hint-seeking behaviour of western scrub-jays in a metacognition task
TLDR
The findings suggest that the scrub-jays can differentiate the states of knowing and not knowing about certain information and take appropriate action to complement their missing knowledge.
Children's capacity to remember a novel problem and to secure its future solution.
TLDR
Verbal reports substantiated the conclusion that by age 4 some children can remember a novel problem sufficiently enough to recognize a solution and select that solution in anticipation of applying it to the problem in the future.

Can animals recall the past and plan for the future?
TLDR
Experiments on memory in food-caching birds show that western scrub-jays form integrated, flexible, trial-unique memories of what they hid, where and when, and suggest that some animals have elements of both episodic-like memory and future planning.
Apes Save Tools for Future Use
TLDR
Bonobos and orangutans selected, transported, and saved appropriate tools above baseline levels to use them 1 hour later, and it was shown that seeing the apparatus during tool selection was not necessary to succeed.
Mental time travel and the evolution of the human mind.
TLDR
It is argued that the human ability to travel mentally in time constitutes a discontinuity between ourselves and other animals and allows a more rapid and flexible adaptation to complex, changing environments than is afforded by instincts or conventional learning.
Anticipation of future events in squirrel monkeys (Saimiri sciureus) and rats (Rattus norvegicus): tests of the Bischof-Kohler hypothesis.
TLDR
Although the rat findings support the Bischof-Kohler hypothesis, the monkey findings challenge it.
Flexible memory processing by rats: use of prospective and retrospective information in the radial maze.
TLDR
Four experiments investigated the content of the memory used by rats in mediating retention intervals interpolated during performance in a 12-arm radial maze and found that the rats used information about previously visited arms but information about anticipated choices following a delay interpolated late in the choice sequence.
Episodic-like memory during cache recovery by scrub jays
TLDR
It is shown that scrub jays remember ‘when’ food items are stored by allowing them to recover perishable ‘wax worms’ (wax-moth larvae) and non-perishable peanuts which they had previously cached in visuospatially distinct sites.
Are animals stuck in time?
TLDR
Research on animals' abilities to detect time of day, track short time intervals, remember the order of a sequence of events, and anticipate future events are considered and it is concluded that the stuck-in-time hypothesis is largely supported by the current evidence.
