Detailed explanation-1: -The appropriate indicator of relatedness is the age of two organisms’ most recent common ancestor. Organisms that share a more recent common ancestor are more closely related than organisms with a most recent common ancestor that is older.
Detailed explanation-2: -DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.
Detailed explanation-3: -What is the best way to determine if two species are closely related? The best way is to compare the DNA of the two species. The more nitrogenous bases and amino acids two species have in common, the more closely related they are.
