Classification
The art of sorting into different groups is referred to as Classification. When sorting a lot of things are put into consideration. For instance one can decide to arrange books in a library in alphabetical order or according to the genre each belong to. Even when arranging alphabetically, it can either be by title or by author. These decision on how to arrange or sort is referred to as the bases or criteria for sorting. In living organisms however, classification is based on the characteristics of the organisms.
Classifying living organisms into groups enable scientist to study them easily as their are a lot of different kinds of organism, and in each group, members have common characteristics.
