Traditional classification is based on shared characteristics.
Further Explanation:
The traditional classification depends upon the difference and similarities of the characteristic. They depend upon the shared characteristics of the organisms. Shared derived characters ensure the common ancestry of the organisms that help in constructing phylogenies. All other derived traits can be a result of convergent evolution and hence can lead to a grouping of two non-related species. They show instant common ancestry between the organisms.
It suggests that lineages having some common traits are related to the evolutionary perspective. By studying the closely related group known as an out-group, the derived traits can be determined. If a character is derived independently in two organisms, there is a doubt regarding the same ancestry. Thus, there are few chances of grouping organisms with different ancestry together. Cladistics is referred to as a process of classifying organisms based on their shared traits. The traditional classification is different from cladistics.
