Answer:
The correct answer is - option B. DNA sequences from different species can be compared, giving us more information about their evolutionary relationships.
Explanation:
The study of the evolution of a species in a longer period of time and its evolutionary relation with other species is phylogeny. DNA is the basis of the molecular phylogeny of a species to find out the evolution of species.
Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.
