A team of scientists is studying a mitochondrial DNA sequence shared by two species, and they determine that the DNA has a constant mutation rate. The DNA sequences of the two species are shown below. Species A: GTAGGCATTCGAT Species B: GCACGCATACGTT The scientists use the idea of molecular clocks to determine that the two species diverged from a common ancestor 40 million years ago. Based on this information, how much more time would it take for the two species to differ by a total of 10 base pairs?
