What is a genetic clock?
Genetic data are used for calculation of prehistoric life forms.
This method involves computing the rate of mutation, which allows us to infer the history of the divergence of life forms from a given point in time. Nucleotide, amino acid, and other sequences are calculated.

Based on the idea that mutations accumulate in the DNA of different species at a relatively constant rate over time, scientists can estimate the time since two species diverged from a common ancestor by comparing the differences in their DNA sequences. This technique is known as a "genetic clock," and it allows scientists to determine how long ago two species shared a common ancestor.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
