Answer: Knowing the characteristics of an individual or its entire population helps identify similarities and differences between individuals of the same kind or different types of organisms. We can learn about natives, places, mother tongues, food habits, cultures, religions, and traditions by identifying individuals and populations. It also helps us in determining relationships between individuals from various populations. This kind of identification and relationship helps easily classify organisms into various categories. Learning the characteristics of populations helps in the study of that population as well as how it might be related to other populations. This method allows us to determine evolutionary relationships between distinct populations.
