How are the areas of study – evolution and classification – interlinked?
Study of evolution and classification are interlinked. We can find the evolutionary relationships by identifying the hierarchy of the characteristics (these are the details of appearance and the behaviour) between the two species which shows the evolution. Classification shows the similarities among the two species which allows us to group them and then do the study of them, with the sharing of their common ancestor. The more similar characters are between two species, more closely they seem to be related with sharing of common ancestor. As shown in the given example in the book, A brother and sister are closely related, having the common ancestors before them, i.e, their parents. Their cousin and the girl are related but less if we compared them to the real brother and sister. This is due to cousins having common ancestors, their grandparents. That is how we can relate the classification of the species to the evolutionary relationship.
