Suppose a segment of mitochondrial DNA (mtDNA) is compared between two similar modern-day species. It is known that this segment of mtDNA changes at a steady rate of one base pair every 4 million years. Compare the sequences of the two mtDNA segments given below. Species A: GCACTAAGCATCGATTT Species B: GCACCAGGCACTGGTTC Use the basic principle of molecular clocks to calculate how long ago the two species diverged from a common ancestor. 12 million years ago 8 million years ago 48 million years ago 24 million years ago
