Answer :
Final answer:
Comparing DNA sequences is the most precise method to determine species relatedness.
Explanation:
Comparing the DNA sequences of two species is the most precise way to determine how closely related they are. DNA carries genetic information, and similarities in DNA sequences indicate a closer evolutionary relationship.
By comparing DNA, scientists can identify specific genetic markers unique to each species, allowing for a more accurate assessment of relatedness. This method provides a molecular level of understanding in evolutionary relationships.
