Answer :
Answer:Molecular clocks are used to compare the number of mutations to determine how long ago a species separated and evolved.
Explanation: Yw.
Answer:
They compare the number of mutations to figure out when species split off and evolved.
Molecular clocks analyze the total amount of distinct nucleotides in two organisms' genomes to determine when they diverged from one another. The dates of evolutionary branch points are determined by the average pace at which a certain gene evolves. The molecular clocks compare the number of mutations to calculate how long ago species split and evolved in this way.
