Studies on the possible adaptive value of anticipatory grief have produced results contrary to expectations: people that show more grief before the death of a loved one with a terminal disease also show more grief afterwards. What is a possible explanation for these findings? Grief is actually not adaptative – it’s just a side effect of our big brain Many other factors influence levels of grief and sadness (gender, past experiences, personality, age) which may obscure any underlying relationship The measurements of grief used in this study were too coarse, some quantitative measurement would be better than three qualitative categories All of the above Suppose you are interested in testing the “goldilocks principle” in the evolution of learning using artificial selection of learning in fruit flies. Specifically, the flies are given the opportunity to learn smells associated with habitat choice and foods. Which of the following predictions is NOT consistent with this hypothesis? Learning evolves in lines where smell-food associations change every generation, but not within generations In lines where smell-food associations change each hour, flies evolve to ignore smell in their food/habitat choice, and have corresponding low learning abilities for those smells In the control lines, where flies experience one odor-food combination consistently across generations, they evolve an innate preference for that odor, with no learning When smell cues are paired with temperature cues, flies evolve the ability to use both cues in the learning process
