Sample Question
As a consequence of size alone, organisms that are large tend to have larger brains than organisms that are small. However, some organisms have brains that are considerably larger than expected for an animal of their size. Data for 14 bird species are listed below. Graph the data and then, based on the data, determine which of the statements below is most reasonable. Deviation from expected brain size, that is the brain size based on body mass alone. (Negative values indicate grain sizes smaller than expected; positive values indicate brain sizes larger than expected.) -1.8 1.2 3.2 -2.4 0.0 -2.0 2.3 2.0 -1.0 -2.1 0.3 3.0 1.3 0.7 Mortality rate 0.9 0.8 0.6 0.9 0.7 0.5 0.6 0.6 0.4 0.7 0.8 0.3 0.3 0.4

Apparently because of the costs associated with increase brain size, there is an upper limit as to how large bird brains can evolve.

Larger than expected brain sizes are associated with lower mortality rates. (This could be the result of large-brained birds having an increased intelligence that gives them an advantage in finding food, or escaping predators, though the data do not address this.)

There is no correlation between brain size and mortality rate. (This could be because of conflicting selective pressures. For example, any advantage of having a relatively large brain, perhaps increased intelligence, may be counter balanced by a disadvantage of having a relatively large brain.

Birds with brain sized that are larger than expected have relatively high mortality rate. (This could result from the metabolic costs associated with maintaining that relatively large brain, though the data do not address this.)
