Encephalization Quotient (EQ) values can be estimated for extinct species because
A) there is a linear relationship between the EQ and time, thus allowing extrapolation
B) extinct species always have the same EQ value
C) we can estimate their body masses from their fossilized remains and their brain masses from the sizes of their fossilized cranial cavities
D) we can always find similar species in existence today to make measurements of
C
