Why is mitochondrial DNA useful for tracking human evolutionary history?

Answer 1

Michael Adams

The mitochondrial DNA is a maternal that is used to construct evolutionary trees.

The maternal DNA of mitochondria is utilized to build evolutionary trees.
The rate of mutations in mitochondrial DNAs is higher than that of nuclear DNA.
The higher rate of mutations in mitochondrial DNAs makes it simple to determine differences between closely related individuals.
The mitochondrial DNAs exhibit similarities with the prokaryotic DNA.

Mitochondrial DNA is useful for tracking human evolutionary history because it is inherited exclusively from the mother, remains relatively unchanged over generations, and has a fast mutation rate, allowing researchers to trace maternal lineages and infer patterns of human migration and population divergence over time.

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.
