Because cerebral lateralization is present in all five vertebrate classes, it must have fundamental survival advantages. It has been suggested that this advantage is that in some instances
A) it may be more efficient for neurons performing the same function to be localized in the same hemisphere.
B) it may be easier for the brain to simultaneously perform two different analyses if they are housed in different hemispheres.
C) cerebral lateralization has accelerated the course of evolution.
D) all of the above
E) both A and B
Question 2
The assumption that cerebral lateralization is an exclusive feature of the hominin brain has been challenged by the discovery of
A) lateralization of function in early vertebrates.
B) right-sided feeding preferences in all five classes of vertebrates.
C) right handedness in nonhuman primates.
D) all of the above
E) none of the above
