Please follow up with an explanation, thanks!

The mitochondrial DNA sequence that is shared by two species has a steady mutation rate. Scientists determine the sequences of these two species to be as follows:

Species A: CAGGCCATTATG
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?

A.) 160 million years
B.) 32 million years
C.) 48 million years
D.) 240 million years

Answer:

well, i think the answer is C.) 48 million years

Step-by-step explanation:

I think its C because the number of G+C content is relative to species differentiation.

Hope this help

Have a nice day!!!!
