Geologists have divided the earth history into time units that are largely based on the earth's biotic composition. The modern geological time scale includes both relative and absolute age dating and represents the most up-to-date assessment of the earth's history.

<span>"Genetic drift is more likely to have an impact on small populations."

If a change in the frequency of the alleles happens then it may cause the disappearance of certain alleles because there are only so many copies.</span>
