Explanation:
Detailed explanation-1: -Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness. Biogeographical patterns provide clues about how species, both alive and extinct, are related to each other.
Detailed explanation-2: -Evolutionists have been particularly excited with DNA advances because the basis of DNA is such that it can be utilized to document the history of evolution. By comparing DNA sequences of genes from one organism to another, we can learn an enormous amount about their relationships.
Detailed explanation-3: -Evolutionary relationship means different species are related to each other according to evolutionary or ancestral history.
