In phylogenetic analysis, what does a "phylogenetic tree" represent?

• A chronological timeline of species extinction.

Why is it important to use multiple genetic markers in phylogenetic analysis?

• To increase the cost of the study.

• To reduce the accuracy of the results.

• To provide a more comprehensive understanding of evolutionary relationships.

• To focus solely on mitochondrial DNA.
