Question

figure 18-15 molecular clock by comparing the dna sequence of two or more species, biologists estimate how long the species have been separated. analyze what evidence indicates that species c is more closely related to species b than to species a?

Explanation:

The closer the DNA sequences of species are, the more closely - related they are. If the DNA sequence of species C is more similar to that of species B than to species A, it indicates that species C is more closely related to species B.

Answer:

The similarity of DNA sequences. If the DNA sequence of species C is more similar to that of species B than to species A, it shows species C is more closely related to species B.
