WHICH OF THE FOLLOWING FOSSIL DISCOVERIES WOULD PROVIDE THE MOST COMPELLING

EVIDENCE THAT PRIMATES AND RODENTS DESCENDED FROM A COMMON ANCESTOR?

A. In strata from 70 Ma (million years ago)you find a fossil almostidentical to living primates and another that is almost identical

to living rodents

B.  A fossil from 40 Ma has general primate features but also has

unique traits that do not occur in living primates

C. Fossil primates are found in Northern Europe where no

primates currently occur but where rodent do currently occur

D.  A series of fossils is found between 70 Ma and 80 Ma that have

triad shared by primates and rodents, with later ones tending to

have either specific rodent or specific primate traits

E.  A fossil from 10Ma has quills identical to porcupines (a kind of

rodent) and a prehensile tail that is identical to New World

monkeys.
