Answer:

132 million years ago

Explanation:

The two DNA mit have a difference of 4 bases. If the frequency of mutation is one every 33 million years. We can stipulate that the time that has passed since the two species diverged from a common ancestor is 132 million years. This can be calculated by multiplying the number of variations by the frequency.

4 (variations) x 33 million years = 132 million years.

Species A mt DNA :  TACAAGATAC

Species B mtDNA:    TACGCGTAAC
