Refer to the figure showing brains of various sizes and complexities.Keep in mind that the species shown can have similar body masses as adults. Which statement is false?
A) Brain size is a better indicator of behavioral complexity than is brain size controlled for body size.
B) Pigs have a better sense of smell than humans.
C) Given that the cerebrum is responsible for learning, conscious motor activity, and memory, the behavior of pigs is more complex than that of alligators.
D) Physiological functions, such as heart rate and breathing, are regulated by the brainstem, which differs little between the species shown.
E) Given that the cerebellum integrates sensory and motor information, we would expect the cerebellum to be better developed in birds than in alligators (these two groups are closely related).

Quizplus · Accepted Answer

The statement that brain size is a better indicator of behavioral complexity than brain size controlled for body size is false. Brain size alone cannot determine behavioral complexity as it must be scaled according to body size.
