Question

Why is DNA a useful evolutionary clock?

Answer 1

Answer:

DNA can be used as the useful evolutionary clock because the mutation takes place due to change in the DNA of the organism.

The organism has been evolving since a very long because of the mutation in the DNA of the organism. The changes that has occurred over a period of time is determined by observing the mutation in the DNA.

As the mutation takes place in the DNA of the organism which is responsible for evolution over a period of time.

Hence, The DNA is useful evolutionary clock.

Answer 2

DNA is an evolutionary clock that's extremely useful in our lives because it mutates. The mutations that occur in our DNA causes the organisms to diverge evolutionarily from one another, providing us our natural clock in the timeline of evolution.
