species b: ccagcctatagg

this dna sequence has a known mutation rate, which the scientists used to calculate that the species diverged from a common ancestor 80 million years ago. using this information, how much more time do you predict will pass before these species differ by a total of eight base pairs?

b.) 32 million years
c.) 48 million years
