Suppose That There Is Evidence That Ancestral Females Travelled Long

Suppose that there is evidence that ancestral females travelled long distances to acquire food,or that males required good memory for locations to find their way home.Why would this evidence be important for the critical evaluation of hypotheses about evolved sex differences in spatial ability

A)  This evidence runs counter to the hypothesized selective pressures that would have created existing sex differences. 
B)  This evidence supports the notion that these sex differences are learned. 
C)  This evidence is irrelevant because ancestral gender roles have no importance for understanding modern socialization processes. 
D)  This evidence is important for predicting what people in primitive societies will be able to do if they are tested for spatial abilities.
