Which of the following best explains a way that a molecular clock can be used?
- the number of dna mutations in an organism is measured over time to determine how long it will take for a new species to evolve.
- the number of dna mutations in a species is compared to the number of dna mutations in another species to determine the relative amount of time each species has been evolving.
- the number of differences in a specific dna sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.
- the number of differences in the dna sequences of two organisms of the same species is averaged to determine how many years of evolution have occurred.
