32. Our understanding of many of the evolutionary relationships among animals changed afterthose phylogenies were based on morphological and molecular data (as opposed to only usingmorphological data). What do these changes indicate?
(A)molecular and morphological studies rarely agree
(B) molecular studies add additional information to morphological studies and improve ourunderstanding of evolutionary history
(C) molecular studies are less reliable than morphological studies
(D) molecular studies are extremely time consuming and expensive and really don't add additionalinformation to our understanding of evolutionary history
