A molecular clock allows differences among genomes to be correlated with the fossil record and dated.

Question

Quizplus · Accepted Answer

A molecular clock uses the rates of genetic mutations to estimate the time of divergence between two species. By comparing the differences in DNA sequences between species and using known mutation rates, scientists can estimate when the two species diverged from a common ancestor. This information can be correlated with fossil evidence to create a timeline of evolutionary history.
