Born Animal: Rats That Live in the Moment

Discovery News reports:

In other news, it appears that rats live mostly in the moment. A study on rodent memory, conducted by University of Western Ontario researchers, found that rats remember, but they do not seem to store memories with a "date stamp" the way that we humans do. This suggests they don't know when the remembered event happened, or how much time has passed since the episode. Perhaps such info wouldn't be helpful to them? Animals evolve what they need to survive, so recounting the exact time and date of a past event probably just wasn't very useful in the rat world. (Although I bet it would be now, such as if a rat could remember the exact time a person puts out yummy dog or cat food each morning.)
