Of course there are 100 reasons to disregard the meaning of a study that involves fruit flies, but this left me a tad disheartened:

After repeating the experiment for 30 generations, the offspring of the learned flies were compared with normal flies. The researchers report in a forthcoming edition of Evolution that although learning ability could be bred into a population of fruit flies, it shortened their lives by 15%. When the researchers compared their learned flies to colonies selectively bred to live long lives, they found even greater differences. Whereas learned flies had reduced life spans, the long-lived flies learned less well than even average flies.
